🎯 firebase_fcm_token

A lightweight Flutter package for app status control with server integration and admin panel. Control your app remotely, crash the app when disabled by server, and manage everything through admin panel.

🚨 Critical Feature: App Crash on Disable

When your app is disabled by the server, the application will immediately crash with an Exception instead of showing a white screen. This ensures complete app control and prevents unauthorized usage.

⭐ Features

• 🚫 App Crash Control - Crashes app immediately when disabled by server
• 🔥 Exception Throwing - Throws clear exception: "UYGULAMA YÖNETİCİ TARAFINDAN KAPATILMIŞTIR!"
• 🛑 Mandatory Stop - No bypass possible, app terminates completely
• 🌐 Server Integration - Connect to your PHP server or custom backend
• 👨‍💼 Admin Panel - Web-based control panel for managing apps
• 📱 Lightweight - No Firebase dependencies, HTTP-only communication
• ⚡ Fast Setup - Easy integration in 5 minutes

🚀 Quick Start

1. Add to pubspec.yaml

dependencies:
  firebase_fcm_token: ^1.1.3

2. Initialize in main.dart

import 'package:flutter/material.dart';
import 'package:firebase_fcm_token/firebase_fcm_token.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Initialize app control
  await FirebaseFcmToken().initialize(
    appName: 'my_awesome_app',
  );

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return FirebaseFcmToken().buildAppStatusWidget(
      child: MaterialApp(
        title: 'My App',
        home: const HomePage(),
      ),
    );
  }
}

⚠️ Behavior When App Disabled

When the server disables your app:

1. Immediate Exception: App throws Exception('UYGULAMA YÖNETİCİ TARAFINDAN KAPATILMIŞTIR! Program sonlandırılıyor...')
2. App Crash: Application terminates immediately
3. No Bypass: Users cannot continue using the app
4. Clear Message: Error message explains why app crashed

  final FirebaseFcmToken _controller = FirebaseFcmToken();

  Future<void> _checkStatus() async {
    try {
      // This will crash the app if disabled by server
      await _controller.refreshAppStatus();
      
      // This code only runs if app is enabled
      print('App is enabled: ${_controller.isAppEnabled}');
    } catch (e) {
      // App crashed due to being disabled
      print('App disabled and crashed: $e');
