MethodChannelFlutterBadgeController class

Implementation of FlutterBadgeControllerPlatform using MethodChannel.

This class communicates with the native platform (Android/iOS) through the flutter_badge_controller method channel.

  • On iOS, it uses:

    • UIApplication.shared.applicationIconBadgeNumber

  • On Android, it sends a broadcast intent (android.intent.action.BADGE_COUNT_UPDATE) which is supported by many OEM launchers (Samsung, Huawei, Xiaomi, etc.). Note: Not all Android launchers support app icon badges.

Example:

await FlutterBadgeController.setBadgeCount(5);   // show badge "5"
await FlutterBadgeController.getBadgeCount();    // returns 5
await FlutterBadgeController.clearBadge();       // reset badge to 0
