2. Additional Requirement: Notifications

Badge count updates should be triggered by local or push notifications.

Required Setup for iOS

Add notification permissions to your Info.plist and ensure plugin registration in AppDelegate.swift.

Usage

Update Badge Count

To update the badge count on supported devices:

import 'package:app_badger/app_badger.dart';

void _updateBadge() {
  AppBadger.updateBadgeCount(5); // Set badge count to 5
}

Remove Badge

To remove the badge count:

import 'package:app_badger/app_badger.dart';

void _removeBadge() {
  AppBadger.removeBadge(); // Remove badge
}

Check if Badge is Supported

To check if the badge functionality is supported on the device:

import 'package:app_badger/app_badger.dart';

void _checkBadgeSupport() async {
  bool isSupported = await AppBadger.isBadgeSupported();
  print("Badge supported: $isSupported");
}

Glassmorphism Badge (In-App UI)

For using the glassmorphism badge in your app's UI:

import 'package:app_badger/app_badger.dart';

Stack(
  alignment: Alignment.topRight,
  children: [
    Icon(Icons.notifications, size: 48),
    GlassMorphismBadge(count: 7),
  ],
)

Glassmorphism Container (UI Backgrounds)

For using the glassmorphism container in your app's UI:

import 'package:app_badger/app_badger.dart';

GlassMorphismContainer(
  child: Column(
    children: [
      // ...your widgets...
    ],
  ),
)

Troubleshooting

• MissingPluginException: Ensure the MethodChannel name is app_badger in both Dart and native code. Do a full restart after plugin changes.
• Badge Not Showing on Xiaomi Devices: Add Xiaomi receiver and permissions in AndroidManifest.xml.
• Badge Not Working: Badge counts may not be supported on all devices; check permissions and settings.
• Notification Badge Only Works After Notification: Badge updates should be triggered by notifications.
