flutter_screen's Introduction

Screen

A Flutter plugin to manage the device's screen on Android and iOS.

Usage

To use this plugin, add screen as a dependency in your pubspec.yaml file.

Make sure you add the following permissions to your Android Manifest

<uses-permission android:name="android.permission.WAKE_LOCK" />

Example

// Import package
import 'package:screen/screen.dart';

// Get the current brightness:
double brightness = await Screen.brightness;

// Set the brightness:
Screen.setBrightness(0.5);

// Check if the screen is kept on:
bool isKeptOn = await Screen.isKeptOn;

// Prevent screen from going into sleep mode:
Screen.keepOn(true);

flutter_screen's Issues

Unhandled Exception: MissingPluginException(No implementation found for method brightness on channel github.com/clovisnicolas/flutter_screen)

i added screen: 0.0.5 in pubspec.yaml and run flutter pub get .
but run main.dart cause the result

When I setState, MissingPluginException

I was ,

in pubspec.yaml
dependencies:
flutter:
sdk: flutter
screen: ^0.0.5
in androidManifest
copy to Paste in my code.
https://pub.dev/packages/screen/example

code

import 'package:flutter/material.dart';
import 'package:screen/screen.dart';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
@OverRide
_MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State {
bool _isKeptOn = false;
double _brightness = 1.0;

@OverRide
initState() {
super.initState();
initPlatformState();
}

initPlatformState() async {
bool keptOn = await Screen.isKeptOn;
double brightness = await Screen.brightness;
setState(() {
_isKeptOn = keptOn;
_brightness = brightness;
});
}

@OverRide
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
appBar: new AppBar(title: new Text('Screen plugin example')),
body: new Center(
child: new Column(children: [
new Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
new Text("Screen is kept on ? "),
new Checkbox(
value: _isKeptOn,
onChanged: (bool b) {
Screen.keepOn(b);
setState(() {
_isKeptOn = b;
});
})
]),
new Text("Brightness :"),
new Slider(
value: _brightness,
onChanged: (double b) {
setState(() {
_brightness = b;
});
Screen.setBrightness(b);
})
])),
),
);
}
}

Successful hot load.... but,
When I setState, I met the "MissingPluginException"

I used flutter 2.0.1 (stable),
I tried to "flutter clean".

Brightness not changing on Android 9.0 Pie

I implemented your example for setting the brightness (on Android) but it doesn't change anything.
Also getting the brightness with Screen.brightness always returns 0, regardless of what i have defined in my settings.

Only screen brightening works, not dimming.

I have an issue where the lowest the screen brightness can go is the brightness the user has set on their phone.
I'm doing this :

Screen.setBrightness(0.0);

Setting the brightness to max does work, however.

Screen.setBrightness(1.0);

Running Android 10
Works on iOS

Null safety support

Null safety is stable now in flutter. Any plan to migrate flutter_screen to null safety?

not support sound null safety

Your plugin is very convenient to use, but the current flutter SDK has introduced null safety to optimize the code of project, and I hope that your plugin can make use of null safety to perfect plugin as soon as possible! Greatfully!

hardcoded MethodChannel name - potential bugs?

I noticed a hardcoded channel name here:

https://github.com/clovisnicolas/flutter_screen/blob/master/lib/screen.dart#L6

Reading the docs https://api.flutter.dev/flutter/services/MethodChannel-class.html

The logical identity of the channel is given by its name. Identically named channels will interfere with each other's communication.

would there be a problem if multiple flutter apps would use this pub?

It is probably because Dart 2.0 introduces strong types, which do not allow implicit casting.

I am going to create a pull request that fixes this problem (at least for me).

On IOS, Screen.setBrightness only works the first time

I have it set on a particular screen to set it to 75%, but if the user navigates away from that screen and sets the brightness to lower, then goes back to that screen, it will not reset the brightness.

I am on IOS 13.2, XCode 11.2.1 (11B500), and Flutter (Channel master, v1.12.4-pre.4, on Mac OS X 10.14.6 18G95, locale en-US)

Deprecated version of the Android embedding

The plugins `screen` use a deprecated version of the Android embedding.

To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Reset user brightness / Turn off plugin

It might be related to this comment: #8 (comment)

It would be great to have a way to reset the user brightness, but more like turning off the plugin.

This is because (as the related comment says) it becomes impossible to manually change the brightness.

// on initState, get original brightness.
_userBrightnessRatio = await Screen.brightness;
...
// This correctly sets the original brightness back, but
// there is no way to change it using the user preferences.
// You need to close the app to be able to change it.
Screen.setBrightness(_userBrightnessRatio);

Do you believe there is a way to do this? I thought of adding the proper method to the https://github.com/clovisnicolas/flutter_screen/blob/master/android/src/main/java/flutter/plugins/screen/screen/ScreenPlugin.java file. I would be willing to create a PR if we could find a solution 😁.

Doesn't work with new flutter

I'm trying to use the plugin with flutter 1.7 but I'm always getting this error

E/flutter (22188): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: MissingPluginException(No implementation found for method keepOn on channel github.com/clovisnicolas/flutter_screen)

E/flutter (22188):
E/flutter (22188): #1 Screen.keepOn (package:screen/screen.dart:11:45)

Seems like some dependencies are missing. I tried rebuilding the app completely. It didn't help

Package transfer

Hey @clovisnicolas,

I'm wondering if you're open to transfer the package on pub.dev, since you haven't done any maintenance in four years. Please let me know.

Support for Flutter Web and Nullsafety

Please add support for flutter web and null safety

Transfer to Flutter Community GH Repo

Please follow instructions on this page:
https://github.com/fluttercommunity/transfer-guide

and the Flutter Community will help to look after unmaintained packages

This will help benefit You as the original developer and the many developers who rely on this package.

Thank you for your attention

screen 0.0.3 requires Dart SDK version <2.0.0

Hej can you remove the SDK restriction version?
I received The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.

Because screen 0.0.3 requires SDK version <2.0.0 and no versions of screen match >0.0.3 <0.1.0, screen ^0.0.3 is forbidden.
So, because depends on screen ^0.0.3, version solving failed.
pub get failed (1)

Thanks in advance!

The brightness value got by Screen.brightness is different from the value of device brightness

Hi,

The version of my testing device is android7.1.1, I found if the adaptive brightness feature is enable, the brightness got by Screen.brightness is different from the actual value of the device brightness.

If I disable the adaptive brightness, the brightness value will be the same as the device brightness, so what can i do to get the actual brightness value when the device enable the adaptive brightness feature??

Thanks!!!!
