Installation

Add this to your package's pubspec.yaml file:

dependencies:
  screenshot_share_telegram: ^0.1.0

Then run:

$ flutter pub get

Usage

Configuration

First, configure the package with your Telegram credentials and preferences:

// In your main.dart file
void main() {
  // Configure the package (do this before runApp)
  ScreenshotConfig.configure(
    // Required for Telegram sharing mode
    telegramToken: 'YOUR_TELEGRAM_BOT_TOKEN',
    telegramChatId: 'YOUR_TELEGRAM_CHAT_ID',
    
    // Optional configuration
    shareMode: ShareMode.telegram, // Options: telegram, localSave, shareWithApps, multiple
    imageQuality: 90, // JPEG quality (0-100)
    fileNamePrefix: 'myapp', // Prefix for filenames
    showButtonsInDebugOnly: true, // Only show buttons in debug mode
  );
  
  runApp(const MyApp());
}

Single-Button Mode

Capture and share screenshots immediately with a single button:

// Wrap your app with the ScreenshotService
return ScreenshotService.wrapScreen(
  child: YourApp(),
  showButton: true, // Show the capture button
  buttonPosition: Alignment.bottomRight, // Position of the button
  buttonColor: Colors.red.withOpacity(0.7), // Button color
);

Dual-Button Mode

Capture multiple screenshots and share them later:

// Wrap your app with the ScreenshotManagerService
return ScreenshotManagerService.wrapScreen(
  child: YourApp(),
  showButtons: true, // Show both buttons
  buttonPosition: Alignment.bottomRight, // Position of buttons
  captureButtonColor: Colors.red.withOpacity(0.7), // Capture button color
  shareButtonColor: Colors.blue.withOpacity(0.7), // Share button color
);

Change Share Mode at Runtime

You can change the share mode at runtime:

// Capture and share with a specific mode
await ScreenshotService().captureAndShare(
  repaintKey,
  overrideMode: ShareMode.shareWithApps,
);

// Or when using the manager service
await ScreenshotManagerService().processScreenshots(
  overrideMode: ShareMode.localSave,
);

Custom Screen Sizes

Customize the screenshot sizes:

ScreenshotConfig.configure(
  screenSizes: [
    {'width': 1080, 'height': 1920, 'suffix': 'phone'},
    {'width': 2048, 'height': 2732, 'suffix': 'tablet'},
  ],
);

Examples

Toggle Between Single and Dual Button Modes

bool _useDualButtons = true;

@override
Widget build(BuildContext context) {
  Widget app = YourAppContent();
  
  if (_useDualButtons) {
    return ScreenshotManagerService.wrapScreen(child: app);
  } else {
    return ScreenshotService.wrapScreen(child: app);
  }
}

Use Inside MaterialApp Builder

MaterialApp(
  // Use builder to wrap your entire app
  builder: (context, child) {
    return ScreenshotManagerService.wrapScreen(
      child: child ?? Container(),
    );
  },
  home: HomeScreen(),
);
