Build

• Build for each arch/mode/profile

Analyze

• Formatting & Linter → #90
• API checker (ensure no internal API is used by the wearable embedder) → #140

Release

• Automatic release (the GitHub Release task didn't work when I tested last time 🤔)
• File server for hosting releases (we need our own domain)
• Admin dashboard (to check the number of downloads for each release, etc.)

Test

• (meta) Add a self-hosted instance to the Pipelines (pricing: $15/month) to run tests on a local machine
• Run integration tests (run sample apps on a set of test devices and check if they behave correctly)
• Run regression tests (measure the performance of sample apps and compare with the previous results)
• Add unit tests for the Tizen embedder and run

flutter#26562 (comment)

The new API was not included in the Flutter 3.0 release but will land in the next stable engine release. We will have to prepare for migration until then.

when I implement presentation displays plugin, engine should provide interface for getting elm window.
I think other plugins may also need this interface in the future.

Issues(Get ecore_wl2_window from elm window)

• Rotation .
• Create egl window fail on RPI.
• Black screen when launch app.

How to reproduce:

1. Fetch flutter-tizen/flutter-tizen#287.
2. Run TIZEN_ENGINE_AZURE_BUILD_ID=699 flutter-tizen precache --tizen.
3. Run any Flutter app in release mode on any of your devices (arm or arm64).

Not sure how to debug because the crash occurs in the UI thread (Dart code), but maybe we can try reverting the Dart runtime version or running an asan build of the engine.

.NET type apps crash on my Tizen 5.5 watch device when run in candidate mode (launched from an existing loader process without creating a new process). The issue is probably related to the EFL preloading feature on watch devices. (Removing files in /usr/share/dotnet.tizen/preload temporarily fixes the problem - only for rooted devices.)

How to reproduce:

1. Create a project and run on a 5.5 watch device:

   flutter-tizen create --tizen-language csharp .
   flutter-tizen run
   

   The app is run in standalone mode when it's launched for the first time after install.
2. Stop the app.
3. Wait for 5 seconds (until a loader process starts) and launch the app again, by clicking an app icon or using app_launcher -s.

The issue doesn't occur on Tizen 6.0 devices because:

• The system freetype library version is newer.
• Apps launch in standalone mode only, because the http://tizen.org/metadata/direct-launch metadata value is by default enabled in tizen-manifest.xml. The metadata was first introduced in Tizen 6.0.

I'm currently writing an experimental embedder that purely depends on wayland so that it can work with other compositors (more specifically Weston) than Enlightenment. I'm not sure if the work will go very well. I'll make updates here when some progress is made.

If anybody is familiar with this topic or has ever considered about the approach, please share your thoughts.

Background?

There are requirements for multiple screens. There's nothing specific, everything can change, but multiple screens don't change. 😄 So I checked how multi-screen support is going on in Flutter. And I found the following:

https://docs.google.com/document/d/11_4wntz_9IJTQOo_Qhp7QF4RfpIMTfVygtOTxQ4OGHY/edit
https://github.com/flutter/flutter/issues/30701
https://github.com/google/flutter-desktop-embedding/issues/98

IMO, Supporting multiple windows didn't seem to happen soon at this moment. So I decided to look for Plan B.
That is EngineGroup feature.(https://flutter.dev/docs/development/add-to-app/multiple-flutters)
Technically, It’s a little different but I thought It would be able to produce similar looking with multi screen app.
So, I aimed the first step of this task to port sample app(https://github.com/flutter/samples/tree/master/add_to_app/multiple_flutters) at tizen.

EngineGroup

As you can see in the example, this is part of how to embed Flutter in a native app. The best way is to embed Flutter in tizen as one of the GUI widgets , but this is not easy In the current implementation. (Many of our rendering behavior are
based on window)
Here is my rough plan based on these.

1. Make windows externally and use them. This will allow us to create and place partial windows at single app. (#98)
2. Create spawn API in embedder.
3. Create FlutterEngineGroup API at native API
4. Port sample app to tizen

(Of course, I am not insisting that this feature should be done this way. Any ideas are welcome. 😄 )

Nice to meet you devs. I'm studying flutter and have a question, so I'm making a sample and writing my opinion here :)

Currently, AddtoApp of flutter-tizen can be implemented by using a window handle. (ecore_wl2, elm_win)

To add the rendered flutter output to the elementary widget, it was not appropriate to use elm_win.
(I tried using other types of windows, but it didn't work as intended. (ELM_WIN_INLINED_IMAGE type of elm_win))

I made a sample by modifying the evas_gl.cc code to use the evas image handle.
The user can get the image handle after set the parent window or parent widget appropriately. And they can add it somewhere.

Below is a sample of this idea.
If a suitable interface and sample code to add parent are presented, users can expect to output FlutterView(?) in EFL-based apps.
(Of course, this is not a nice interface unless multi-instance (maybe FlutterGroup?) is applied.)

Apps cannot be started on a Tizen 4.0 device/emulator (regardless of the build mode or app type) after Flutter 2.0 update. Wanchao has initially reported this issue by testing on a Tizen 4.0 watch emulator (with a plugin sample) and the issue has been confirmed to be applicable for any Tizen 4.0 device and any app.

Typically, a Flutter app begins execution at the Dart method called main(), however this is not required. Developers can specify a different Dart entrypoint

Font not rendering issues were noticed in:

• #39
• flutter-tizen/flutter-tizen#72

Even with some patches, the problem is not fully fixed. I tried to solve the problem, but I'm kind of stuck. I hope someone could give me some advice. Or, you could try to fix it if you're interested.

Using fontconfig

Problem: Using fontconfig matches wrong font style for English language on wearable devices.

On wearable devices, English text is matched to some other language font that doesn't contain glyphs for Latin characters. Skia doesn't get the font information from running fontconfig executables, it uses fontconfig apis to parse the configuration file itself. The problem happens only when system font is set to "default"(SamsungOneUI).

Fontconfig configuration file is in read-only file system: /etc/fonts, so maybe I shouldn't be changing this file directly, but change the skia code that parses it?

Wearable device:

# English text should be matched to "SamsungOneUI", but it gets matched to some other font in this list:

Fonts selected by "SamsungOneUI", 15 styles selected.
I/ConsoleMessage( 2451): family name for font is...: BreezeSansMyanmar

If we don't use fontconfig(the current engine build), characters that use custom fonts can't use system fallback fonts if those characters don't have matching glyphs in the custom font files.

Similarly to flutter-tizen/flutter-tizen#60, here are some works to be done for the engine and our embedder. Please open a dedicated issue or PR if you are interested with any.

• Alternative logging method on TVs (avoid using __dlog_print) → #67
• Advanced continuous integration → Addressed by #89
• Non-fatal error "xkbcommon: ERROR: couldn't find a Compose file for locale" on app launch (unrelated to Flutter) → #91
• Endless thread creation on watch devices ("Thread added to display, Thread removed to display, ...") → Not reproducible
• Implement platform channel methods (setPreferredOrientations, vibrate, Clipboard.*, play) → #65, #75, #79, #84
• Analyze performance issues (gallery app is sluggish, frame janks)
• Investigate why SkSL shaders cannot be collected on Tizen devices → #55
• Symbol resolution fails for system libraries in DevTools stack traces → #95
• Cupertino widget animation flickering issue on TM1 devices → flutter-tizen/embedder#5
• Enable arm64 engine builds → #63
• Remove Tizen-specific texture APIs → #82
• Overall refactoring → WIP

https://github.com/rwalczyna/engine/blob/app_control/shell/platform/tizen/channels/app_control_channel.cc#L144

It has the same purpose as GetValueFromEncodeableMap in platform_view_channel.cc
I'd like to ask for a little refactoring so that all tizen channels can use this template in common.

Even without splash screen, when launching app newly on wearable, a blank screen is displayed once for a while.
If you set elm_win_alpha_set as a true, it may seem to be solved, but it is not right to always treat it as transparent(This may affect performance badly).

The keyboard input system is being reworked in the upstream (more processing should be done by the embedder side), so we'll need to make some changes to our embedder sooner or later.

external texture's format are fixed as GL_RGBA8, However, the TBM surface has a variety of formats.
We've started to worry about this while developing our plugin.
here is our discussion flutter-tizen/plugins#70 (comment)

I'm still surveying about the subject. This issue is to share and discuss what I'm currently looking into.

System UI is an application that runs when a device is powered on. It keeps track and provides control to system-wide setting, status, notification, etc. Examples: lockscreen UI, navigation bar, notification app, status bar, volume UI, ...

I'm posting a youtube link, What's new in System UI, so that you can get a sense on what a system ui might be in Android.

I'm looking into the following subjects in consideration of some performance metrics such as start-up time, response time, and memory consumption:

• component based application
• add-to-app
• lightweight flutter instances

Target host

• MacOS X

The problem is described in: #53 (comment)

run an app in profile mode and open the Performance view in Flutter DevTools, you will see this screen:

As you can see in the stack traces at the bottom of the view (CPU Flame Chart), symbols are resolved to their offsets within the shared objects (/proc/self/fd/35/lib/libflutter_engine.so+0x.....) but not their actual names. I'm not sure whether this is normal (because the symbols were stripped out).

SystemSound.play method, handled by "flutter/platform" message channel is not implemented.

It makes managing our commit history easier (no need to rebase the entire commit tree when updating the engine).

What is shader compilation jank?

https://flutter.dev/docs/perf/rendering/shader

How to enable SkSL warm-up on Tizen?

1. Set the FlutterProjectArgs.persistent_cache_path value to either a system temp directory or the app cache directory before starting the engine. Alternatively, the cache directory can be set by implementing fml::paths::GetCachesDirectory() in fml/platform/linux/paths_linux.cc (not tested). Shaders will be stored to this directory on the first run of an app, and the cached shaders will be used on subsequent runs.

2. You can optionally bundle the shaders with a tpk (as a json file in res/flutter_assets) to accelerate the first run of the app on other devices: https://flutter.dev/docs/perf/rendering/shader#how-to-use-sksl-warmup

Pros and cons

• Reduced shader compilation janks (not confirmed on Tizen - how can we measure this accurately?)
• Increased app startup latency because cached/bundled shaders need to be precompiled
  • The last measurement result: #55 (comment)
• Slightly larger app size due to bundled shaders

안녕하세요.

키보드 및 리모컨 에서 발생하는 키값에 대해 아래 URL내에 있는 sample을 통해 발생되는 몇가지 키를 확인해 봤습니다.
https://api.flutter.dev/flutter/services/LogicalKeyboardKey-class.htm

리모컨의 상하좌우 키는 Arrow Up, Down, Left, Right로 logicalKey, pysicalKey에 매칭이 잘되어 있는 것을 확인했고
X86AudioPlay의 경우 키보드로 매칭되는 값이 없어서 "Media Play"로 신규로 정의 된 것도 확인했습니다.

이외에 채널 업/다운/Mute, Red, Blue,Green과 같은 키는 F1~12사이의 function키로 매칭이 되는 것으로 확인이 되는데요.
이것은 어떤 기준으로 이렇게 매칭이 됐는지 잘 모르겠네요.

지원되는 리모컨 키가 아래와 같이 다수 있는데요.
이 값들이 logicalKey, pysicalKey에서 어떤 값으로 전달 되는지 정리된 자료가 있으시면 공유 부탁 드립니다.

Default apps behave as if the back button was pressed when the esc key is pressed.
and there is no way to terminate the flutter app after launching it(except shell command) on IoT profile :(

Currently it's not possible to do source line-level debugging of the engine and embedder binaries (even with so.unstripped binaries) because the compiler strips out all debugging information (-g0) by default:

• https://github.com/flutter/buildroot/blob/4660f4a166979c64ff56f6b856b44ccc1dba5c63/build/config/BUILDCONFIG.gn#L401
• https://github.com/flutter/buildroot/blob/4660f4a166979c64ff56f6b856b44ccc1dba5c63/build/config/compiler/BUILD.gn#L919

Extracting debug info files from unstripped binaries (and publishing them along with engine releases) will make it convenient to debug the engine and embedder via gdb and gdbserver.

Sample Code
import 'package:flutter/material.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget
{
@OverRide
Widget build(BuildContext context) {
// TODO: implement build
return MaterialApp(
home: Scaffold(
backgroundColor: Colors.red,
body: Center(child: Column(
children: [
Image.asset("assets/flutter_icon.png"),
Text("sojaasadaddd")
],
)),
),
);

}
}

Problem

• If you use localeResolutioncallback, you get the wrong locale value
• Sample codes

  // ...
  import 'package:flutter_localizations/flutter_localizations.dart';
  // ...
        localizationsDelegates: [
          GlobalMaterialLocalizations.delegate,
          GlobalWidgetsLocalizations.delegate,
          GlobalCupertinoLocalizations.delegate,
        ],
        localeResolutionCallback:
            (Locale locale, Iterable<Locale> supportedLocales) {
          print("localeResolutionCallback!!");
          print("locale.countryCode : " + locale.countryCode.toString());
          print("locale.languageCode : " + locale.languageCode.toString());
          return locale;
       }

How to reproduce

1. Launch the app
2. Change device language to another language
3. Resume the app

as is

• The locale value is always wrong.
  

expected

• The locale value should reflect the language of the device.
  

The "Destory" occurs 27 times in the repo. This one is part of public API and should probably be fixed. But I guess current name should continue to work to maintain compatibility.

Problem

1. When the device is rotated, an animation of rotating the window should occur but it doesn't
2. After the device is rotated, the keyboard should also be positioned correctly but it doesn't.

As-is

• When the device is rotated, No rotating animation occurs.
• screenshot
  

Expected(android)

• When the device is rotated, you can see the animation of rotating the window
• screenshot
  

Details

To solve these problems, I tried setting available rotation degrees on the window.

ecore_wl2_window_available_rotations_set

If you use the above API and you rotate the actual device, you can see that the window is also rotated according to the device orientation with an appropriate rotating animation. the keyboard is positioned also correctly.
But after that, the screen looks frozen.
*If you are using the scrollable sample app, you can easily see that the screen is frozen after rotating the device with the above API.

I tried the following to analyze and to solve the problem, but it didn't work.

• Remove gl surface transformation
  • The screen may appear partially frozen. when pause-resume occurs, nothing will be shown(black screen).
• After the device is rotated, re-create egl window surface after device rotated on the render thread
  • If you create a surface and clear the surface with any color, you can see that color momentarily. // It's natural.
  • However, once a rotation occurs, you can not see that color anymore. // this is very weird.
• After the device is rotated, re-create wl2 window and egl window surface on the render thread
• Create wl_egl_window* from Ecore_Wl2_Window and use it to create egl window surface

Please let me know if you know anything about this.

Previous discussion: #75 (comment)

• The embedder should properly control its logging level based on the verbose_logging switch (which is enabled by flutter-tizen run --verbose-system-logs).
  • Example:
    

    engine/shell/common/shell.cc

    Lines 228 to 231 in 9f08d18

    	fml::LogSettings log_settings;
    	log_settings.min_log_level =
    	settings.verbose_logging ? fml::LOG_INFO : fml::LOG_ERROR;
    	fml::SetLogSettings(log_settings);

• Remove unnecessary logs in the embedder or make them more informative. We should remove all occurrences of FT_LOGD and use only FT_LOGI/W/E.

I am researching for rendering flutter-tizen in NUI (Tizen Natural User Interface (C#))
For this, I must use DALi(Tizen C++ UIFW) in engine(tizen renderer).
Among the DALi APIs, there is an API that returns std::string and when I want to use this API, the link error occurred in engine build.
( ex: const std::string& Dali::Toolkit::ImageUrl::GetUrl() const)

tizen_renderer_ecore_wl2.cc:(.text._ZN7flutter21TizenRendererEcoreWl28SetupEGLEv+0x2d3): undefined reference to `Dali::Toolkit::ImageUrl::GetUrl() const

I found symbol for this API with the nm command. there is a [abi:cxx11] tag.

~/dev/os/engine/src ((HEAD detached at 4660f4a)) 16:08:11 $ nm -gDC tizen_tools/sysroot/x86/usr/lib/libdali2-toolkit.so | grep ImageUrl::GetUrl
0020fade T Dali::Toolkit::ImageUrl::GetUrl[abi:cxx11]() const

I was studying this and found that the engine compile script need __GLIBCXX_USE_CXX11_ABI = 1 //or 0 define.
(https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html)
I added it to build script and tried to build, but the problem was not resolved.

If you guys has any ideas for script modifications to use [abi:cxx11] api, please let me know.

I am trying to build engine from flutter-tizen/engine repo, to use it with flutter. I am following the manual from https://github.com/flutter-tizen/engine/wiki/Building-the-engine and I have been stuck on point 5. from this part of the manual https://github.com/flutter/flutter/wiki/Setting-up-the-Engine-development-environment:

5. gclient sync in that [flutter/engine] directory. This will fetch all the source code that Flutter depends on. Avoid interrupting this script, as doing so can leave your repository in an inconsistent state that is tedious to clean up. (This step automatically runs git clone, among other things.)

When I use "https://github.com/flutter-tizen/engine.git" as the "url" in .gclient file, the gclient sync command fails with the following output:

(flutter) [~/prog/github/flutter/engine]$ gclient sync                                                                                            *[master]

The contents of .gclient file in flutter/engine:

solutions = [
  {
    "managed": False,
    "name": "src/flutter",
    "url": "https://github.com/flutter-tizen/engine.git",
    "custom_deps": {},
    "deps_file": "DEPS",
    "safesync_url": "",
  },
]

As a workaround I have changed the version of package_config in flutter/engine/src/flutter/tools/generate_package_config/pubspec.yaml from any to 1.9.3 - after that change gclient sync succeeds. Nevertheless, this is only a workaround.

Could you please help me fixing the problem?

On TV, a focus cannot move to specific widgets in an app through arrow buttons (D-pad) on remote controls if the app has one or more text field widgets.

For example, in the "share_plus" plugin demo, the "Share subject" text field and the "Share" button can never get a focus because the text field on the top ("Share text") swallows all arrow button clicks. (I cannot upload a screenshot due to the company firewall.)

This is a TV-specific issue because the only input device for TV is a remote control by default. Other profiles and platforms (such as Android) do not have this problem because they all support touch/pointer-based navigation.

This issue has been reported in #53:

Non-fatal error "xkbcommon: ERROR: couldn't find a Compose file for locale" on app launch (unrelated to Flutter)

Reproduction by @bbrto21:

Launch Settings
Go - Language and input
Go - Display language
Choose a language other than English
Launch flutter-app

dlog output:

E/ConsoleMessage(24758): xkbcommon: ERROR: couldn't find a Compose file for locale "pl_PL.UTF-8"

Dart messages should be logged through the new logging callback recently added to the embedder APIs as suggested by #105.

The current plan:

• When running in release mode, only Dart messages are logged to dlog.
• When running in debug mode, Dart messages and all stdout/stderr messages are logged to dlog.

Problem

• If you run the Gallery app after setting the device language to Korean, Korean will not be displayed properly.
  

Problem

Unmanaged APIs should not be used for app store registration.
(This issue is also related to flutter-tizen/flutter-tizen#10. because wayland related functions are also unmanaged APIs)

I know coverty scan is a good tool, and if you're lucky you can find a place to fix it. (Unfortunately not in most cases. 😄 )

For fun, I ran it based on the current latest and got the following results.

Here is tizen only
whole result

I'm going to try and see if there's anything I can do. Those who are interested may want to take a look.

안녕하세요.

TV에 Sample App을 올려놓고 테스트를 하다보면,
일부 배경이 흰색을 가진 element에서는 Focus가 잘 눈에 띄지 않아
개선이 가능할지 문의하고자 이슈를 남깁니다.

혹은 앱 개발자가 Focus를 받은 widget에 대해 테두리를 추가하도록
구현 가이드를 해야할 부분인지 답변 주시면 감사하겠습니다.

There is a use case where the app needs to disable quickpanel pull-down gesture to prevent users from exiting the app. I know that flutter-tizen/flutter-tizen#246 is fixed by #197. We need a way to control this behavior.

• Clang 12 build flag (-Wno-psabi) issue
  • Fuschia/Linux build now uses clang 12 by default but the Tizen toolchain is still based on clang 10.
  • Building the Tizen engine with the Fuschia toolchain has failed because required libraries are not available for armv7-linux-gnueabi target (see buildtools/linux-x64/clang/lib).
  • Thus, similarly to the -Wno-non-c-typedef-for-linkage flag, we have to remove the new flag from build/config/compiler/BUILD.gn manually.
• TextInputModel API changes (flutter#21612, flutter#21854)
  • Done!
• SDK artifacts cross-compilation issue
  • The same build error as flutter/flutter#74322 which was caused by flutter#20254.
  • We don't need to cross-build SDK artifacts for Tizen armv7l and x86. So we need to patch the build rule temporarily. (I'm not going to PR it in the upstream right now.)
• flutter_texture_registrar.h API conflicts
  • The following APIs have been added (flutter#19405):
    • FlutterDesktopRegistrarGetTextureRegistrar
    • FlutterDesktopTextureRegistrarRegisterExternalTexture
    • FlutterDesktopTextureRegistrarUnregisterExternalTexture
    • FlutterDesktopTextureRegistrarMarkExternalTextureFrameAvailable
  • but we already have:
    • FlutterPluginRegistrarGetTexture
    • FlutterRegisterExternalTexture
    • FlutterUnregisterExternalTexture
    • FlutterMarkExternalTextureFrameAvailable
  • I tried to remove our header and use theirs by renaming the functions in flutter_tizen.cc file, but the parameter tbm_surface was not available for FlutterDesktopTextureRegistrarMarkExternalTextureFrameAvailable. How should we deal with this? @xiaowei-guan @bbrto21
  • My attempt: swift-kim@1d72ddb (see the commented out section in flutter_tizen.cc)
• Embedder API changes?
  • I haven't checked yet. Done

https://medium.com/dartlang/dart-2-15-7e7a598e508a#0c15

The feature is currently only enabled for Android 64-bit by default.

We need to check if it can be enabled for Tizen arm64 targets.

Tested on emulator mobile-6.0-x86
TextInputType.numberWithOptions with decimal and signed option doesn't work.

Numpad, backward and enter buttons are enabled,
but other buttons are disabled.

Decimal and minus signs are not added to the field.

TextField(
              controller: controller,
              keyboardType:
