This Flutter plugin you can use to change the badge on the icon of your app
- iOS
- Android - some Android devices (the official API does not support the feature, even on Oreo)
- MacOs
- Windows - work in progress (need help)
- Linux - work in progress (need help)
On iOS, the notification permission is required to update the badge. It is automatically asked when the badge is added or removed.
Please also add the following to your Info.plist:
<key>UIBackgroundModes</key>
<array>
<string>remote-notification</string>
</array>
On Android, no official API exists to show a badge in the launcher. But some devices (Samsung, HTC...) support the feature. Thanks to the Shortcut Badger library, ~ 16 launchers are supported.
First, you just have to import the package in your dart files with:
import 'package:flutter_app_icon_badge/flutter_app_icon_badge.dart';
Then you can add a badge:
FlutterAppIconBadge.updateBadge(1);
Remove a badge:
FlutterAppIconBadge.removeBadge();
Or just check if the device supports this feature with:
FlutterAppIconBadge.isAppBadgeSupported();
Another useful method in this plugin - detect if flutter desktop window in focus or not:
FlutterAppIconBadge.isAppBadgeSupported();
