🚀 Quick Start

Installation

dependencies:
  flutter_dev_panel: ^1.1.2
  
  # Add modules as needed
  flutter_dev_panel_console: ^1.1.2    # Logging
  flutter_dev_panel_network: ^1.1.2    # Network monitoring
  flutter_dev_panel_performance: ^1.1.2 # Performance tracking
  flutter_dev_panel_device: ^1.1.2      # Device info

Basic Setup

import 'package:flutter_dev_panel/flutter_dev_panel.dart';
import 'package:flutter_dev_panel_console/flutter_dev_panel_console.dart';
import 'package:flutter_dev_panel_network/flutter_dev_panel_network.dart';

void main() async {
  // Initialize with automatic Zone setup for full functionality
  await DevPanel.init(
    () => runApp(const MyApp()),
    modules: [
      const ConsoleModule(),     // Auto-captures print statements
      NetworkModule(),           // HTTP/GraphQL monitoring
      const PerformanceModule(), // Auto-tracks Timers
    ],
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      builder: (context, child) {
        // Wrap your app with DevPanelWrapper
        return DevPanelWrapper(
          child: child ?? const SizedBox.shrink(),
        );
      },
      home: MyHomePage(),
    );
  }
}

🔧 Integration Examples

Network Monitoring

// Dio
final dio = Dio();
NetworkModule.attachToDio(dio);

// GraphQL
final link = NetworkModule.createGraphQLLink(
  HttpLink('https://api.example.com/graphql'),
);
final client = GraphQLClient(link: link, cache: GraphQLCache());

// HTTP
final client = NetworkModule.createHttpClient();

Environment Management

// Get environment values
final apiUrl = DevPanel.environment.getString('api_url');
final isDebug = DevPanel.environment.getBool('debug');

// Listen to changes
DevPanel.environment.addListener(() {
  // Update your services when environment changes
});

Access Methods

// Programmatic access
DevPanel.open(context);

// Via floating action button (default)
// Via shake gesture on mobile
// Configure in DevPanelConfig

🛡️ Production Safety

Flutter Dev Panel is designed with production safety as a priority:

# Normal release build (panel disabled, zero overhead)
flutter build apk --release

# Internal testing build (panel enabled)
flutter build apk --release --dart-define=FORCE_DEV_PANEL=true

• Debug Mode: Automatically enabled
• Release Mode: Completely removed by tree-shaking
• Force Enable: Optional for internal testing builds
