Installation

Add this to your pubspec.yaml:

  alpha_clipboard: ^0.1.0

Then run:

flutter pub get

Getting Started

Initialize the clipboard at the start of your app:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  // Initialize with auto-save enabled and history capacity
  await AlphaClipboard.initialize(
    autoSave: true,
    maxHistoryItems: 50,
  );
  
  runApp(MyApp());
}

Basic Usage

Copy and Paste

// Copy text to clipboard
await AlphaClipboard.copyText("Hello World!");

// Paste text from clipboard
String? text = await AlphaClipboard.pasteText();

Using the Clipboard Widget

AlphaClipboard.clipboardWidget(
  onCopy: (text) {
    print('Copied: $text');
  },
  onPaste: (text) {
    if (text != null) {
      print('Pasted: $text');
    }
  },
  showHistory: true,
  onHistoryItemSelected: (text) {
    print('Selected from history: $text');
  },
)

Clipboard History Management

// Get all history items
List<String> history = AlphaClipboard.getHistory();

// Clear history
await AlphaClipboard.clearHistory();

// Manually save current history
await AlphaClipboard.saveHistory();

// Restore saved history
await AlphaClipboard.restoreHistory();

Advanced Customization

Custom Theme

final myTheme = ClipboardThemeData(
  backgroundColor: Colors.blue[50],
  buttonColor: Colors.indigo,
  textStyle: TextStyle(color: Colors.black87),
  borderRadius: BorderRadius.circular(12.0),
  elevation: 4.0,
  padding: EdgeInsets.all(20.0),
);

AlphaClipboard.clipboardWidget(
  onCopy: (text) {},
  onPaste: (text) {},
  theme: myTheme,
)

Using Preset Themes

// Light theme
final lightTheme = ClipboardThemeData.light();

// Dark theme
final darkTheme = ClipboardThemeData.dark();

// Modify preset theme
final customDarkTheme = ClipboardThemeData.dark().copyWith(
  buttonColor: Colors.purple,
  elevation: 8.0,
);

Demo App

The package includes a complete example app demonstrating all features:

cd example
flutter run

Implementation Details

AlphaClipboard uses a combination of:

• Flutter's Clipboard API for system clipboard access
• SharedPreferences for persistent storage of clipboard history
• Custom widgets and themes for UI representation

Testing

The package properly handles clipboard operations in test environments by maintaining a local reference to the last copied text, making it testable without mocking the system clipboard.
