flowder's Introduction

Flowder

Handle your file downloads status in a more simple and easy way 💓

pubspec.yaml

dependencies:

flowder: ^0.2.0

Examples

Basic

To start using flowder, is required to do the following setup.

fina downloaderUtils = DownloaderUtils(

progressCallback: (current, total) {

final progress = (current / total) * 100;

print('Downloading: $progress');

},

file: File('$path_to_store_file/200MB.zip'),

progress: ProgressImplementation(),

onDone: () => print('Download done'),

deleteOnCancel: true,

);

final core = await Flowder.download(

'http://ipv4.download.thinkbroadband.com/200MB.zip',

downloaderUtils);

To start a new download.

core.download(url, downloaderUtils);

To resume a download.

core.resume();

To cancel a download.

core.cancel();

To pause a download.

core.pause();

Advanced

If you require an example using internet connection checker, please go to the folder advanced example. The stack used is:

get_it
injectable
riverpod
path_provider
connectivity_plus (this is the best plugin to check internet connection, the others were buggy 😢

Delete downloaded file

From the documentation there is download and cancel, but is there a way to delete a previously downloaded file rather than having to use File().delete() ?

[Suggestion] Notifications.

Hello @Crdzbird
Thanks for the package.
I would like to suggest few features related to notification that make sense. and I would be happy to work on PR.

Show downloaded progress via notification [using flutter_local_notification].
Once the download is completed show the completed download notification
After download clicking on the notification will open that file.

Let me know what you think.
Feedback is welcome.
Thanks

I am building an AAR and Framework that is logic only and has no UI. Instead of the module starting a flutter view, I just call WidgetsFlutterBinding.ensureInitialized(); and then setup a channel. On the native Android side, I warm up the FlutterEngine in the app object as documented by Flutter. When I try to download a file, I get the following error.

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Null check operator used on a null value
    #0      Flowder.initDownload (package:flowder/src/flowder.dart:54:70)
    <asynchronous suspension>
    #1      Flowder.download (package:flowder/src/flowder.dart:29:28)
    <asynchronous suspension>

Here is my code snippet:

final downloaderUtils = DownloaderUtils(
  progressCallback: (current, total) {
    final progress = (current / total) * 100;
    print('Downloading: $progress');
  },
  file: File('$appDocPath/puppy.jpg'),
  progress: ProgressImplementation(),
  onDone: () => print('Download done'),
  deleteOnCancel: true,
);

final DownloaderCore core = await Flowder.download(
    _FILE_URL,
    downloaderUtils);

Support for multiple simultaneous downloads

Hi there,
Thank you for making making Flowder publicly available. I was just wondering if there is any possibility of supporting multiple simultaneous downloads. I am going to use this for a real project.

'VoidCallback' isn't a type

i get this error on build
.
Error: Type 'VoidCallback' not found.
../…/utils/downloader_utils.dart:23
final VoidCallback onDone;

Re-downloading a file appends to itself instead of overwriting

Hi, when I re-download a file, the file appends to itself instead of overwriting it. For example, if I have an already downloaded file that is 10MB in size and I redownload the file, its size will be 20 MB instead of the same 10 MB. I could use a check to see if the file exists, but the file should still be overwritten instead of appended to itself. Also, if the internet connection fails, the incomplete download does not get deleted.

Here's my code:

if (await InternetConnectionChecker().hasConnection) {
      final downloaderUtils = DownloaderUtils(
        progressCallback: (current, total) async {
          final int progress = ((current / total) * 100).toInt();
          if (progress == 100) {
            await flutterLocalNotificationsPlugin.cancel(123);
          }
        },
        file: File(filePath),
        progress: ProgressImplementation(),
        // ignore: avoid_print
        onDone: () {
          SnackBar downloadFinished = SnackBar(
            content: Text("Finished downloading $itemName"),
            behavior: SnackBarBehavior.floating,
            duration: Duration(seconds: 3),
          );
          ScaffoldMessenger.of(context).showSnackBar(downloadFinished);
        },
        deleteOnCancel: true,
      );
      final core = await Flowder.download(fileUrl, downloaderUtils);

      await flutterLocalNotificationsPlugin.show(123, "Downloading file $itemName, \nplease wait.", "", notificationDetails);
    } else {
      await flutterLocalNotificationsPlugin.cancel(123);
      SnackBar downloadFailed = SnackBar(
        content: Text("Download of $itemName failed. Please try again"),
        behavior: SnackBarBehavior.floating,
        duration: Duration(seconds: 3),
      );
      ScaffoldMessenger.of(context).showSnackBar(downloadFailed);
    }

Set-up authentication for download

Hi,

I need to use flowder to download videos for a mobile application that I am currently developing. Now, the download API requires me to send a Bearer token and "Content-Type": "application/x-www-form-urlencoded" for downloading the video.

I am unable to understand how to set this up in Flowder. Can you please advice me ?

Regards,
Ameya

Firebase Storage download error

When downloading an mp3 from Firebase Storage I get an error code [403] when the download has progressed to about 3-5%. I have to click continue in the debugger for it to continue downloading, which it does and finishes perfectly fine. What's the error code referring to? My internet connection is not an issue when downloading (1gbps download/upload).

when i run example code it raised exception "Null check operator used on a null value"
