Flutter Badge Controller

A simple Flutter plugin to manage app icon badges on iOS and Android.

• iOS: Uses UIApplication.shared.applicationIconBadgeNumber.
• Android: Sends a broadcast intent (android.intent.action.BADGE_COUNT_UPDATE) supported by many OEM launchers (Samsung, Huawei, Xiaomi, etc.).
  ⚠️ Not all Android launchers support app icon badges. Stock Android (Pixel) only shows badges via notifications.

Features

• Set app icon badge count
• Clear badge
• Get current badge count
• Easy-to-use static API (FlutterBadgeController)

Usage

import 'package:flutter_badge_controller/flutter_badge_controller.dart';

void main() async {
  // Set badge count to 5
  await FlutterBadgeController.setBadgeCount(5);

  // Get current badge count
  int? count = await FlutterBadgeController.getBadgeCount();
  print("Current badge count: $count");

  // Clear badge
  await FlutterBadgeController.clearBadge();
}

iOS Setup

1. Make sure to request notification permission with .badge option:

import UserNotifications

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
    if let error = error {
        print("Permission error: \(error)")
    }
}

2. Add usage description in Info.plist (optional but recommended):

<key>UIBackgroundModes</key>
<array>
  <string>remote-notification</string>
</array>

3. Badge will only show if the user allows notifications.
