Snackbar Examples #

Basic Snackbars

final snackbarManager = AdaptiveSnackbarManager.instance;

// Success snackbar
await snackbarManager.showSnackbar(
  context,
  SnackbarConfig(
    snackbarType: SnackbarType.success,
    platformType: PlatformDetector.currentPlatform,
    message: 'Operation completed successfully!',
  ),
);

);

await snackbarManager.showSnackbar(context, config);

Loading Snackbar with Controller

// Loading snackbar with controlled dismissal
final loadingController = snackbarManager.showLoading(
  context: context,
  message: 'Processing data...',
  cancellable: true, // User can dismiss loading
  showProgress: true,
);

// Update progress and message
loadingController.updateProgress(0.5);
loadingController.updateMessage('Halfway done...');

// Complete or cancel
loadingController.complete('Processing completed!');
// or loadingController.cancel();

Multiple Snackbars with Stack Behavior

// Single stacked snackbar
await snackbarManager.showSnackbar(
  context,
  SnackbarConfig(
    snackbarType: SnackbarType.info,
    platformType: PlatformDetector.currentPlatform,
    message: 'Stacked snackbar',
    position: SnackbarPosition.bottom,
    behavior: SnackbarBehavior.stack, // Use stack behavior for multiple snackbars
    duration: const Duration(seconds: 5),
  ),
);

// Multiple snackbars stacked (max 5 visible at once)
final messages = ['Task 1 Complete', 'File Uploaded', 'Sync Finished'];
final types = [SnackbarType.success, SnackbarType.info, SnackbarType.success];

for (int i = 0; i < messages.length; i++) {
  await snackbarManager.showSnackbar(
    context,
    SnackbarConfig(
      snackbarType: types[i],
      platformType: PlatformDetector.currentPlatform,
      message: messages[i],
      position: SnackbarPosition.bottom,
      behavior: SnackbarBehavior.stack,
      duration: const Duration(seconds: 6),
      showIcon: true,
    ),
  );
}

// Customize behavior limits
snackbarManager.updateBehaviorSettings(
  maxSimultaneous: 5, // Allow up to 5 simultaneous snackbars
);

Toast Examples #

Basic Toast Notifications

final toastManager = AdaptiveToastManager.instance;

// Info toast
await toastManager.showInfo(
  context,
  message: 'This is an info message',
  title: 'Information',
);

// Success toast
await toastManager.showSuccess(
  context,
  message: 'Data saved successfully!',
  duration: const Duration(seconds: 3),
);

// Error toast
await toastManager.showError(
  context,
  message: 'Failed to load data',
  title: 'Error',
);

Custom Toast

await toastManager.showCustom(
  context,
  content: Container(
    padding: const EdgeInsets.all(16),
    decoration: BoxDecoration(
      color: Colors.blue,
      borderRadius: BorderRadius.circular(8),
    ),
    child: const Text(
      'Custom Toast Content',
      style: TextStyle(color: Colors.white),
    ),
  ),
  duration: const Duration(seconds: 4),
);

Column Layout Toast

// Show toast in column layout mode
await toastManager.showToast<String>(
  context,
  ToastConfig(
    toastType: ToastType.info,
    platformType: PlatformDetector.currentPlatform,
    message: 'Column layout toast',
    title: 'Information',
    position: ToastPosition.bottomCenter,
    layout: ToastLayout.column, // Use column layout
    duration: const Duration(seconds: 4),
  ),
);

// Multiple toasts in column - max 4 visible at once
for (int i = 1; i <= 6; i++) {
  await toastManager.showToast<String>(
    context,
    ToastConfig(
      toastType: ToastType.success,
      platformType: PlatformDetector.currentPlatform,
      message: 'Toast #$i',
      layout: ToastLayout.column,
      position: ToastPosition.topCenter,
    ),
  );
}
// Only 4 toasts will be visible at once in column mode

Advanced Toast Timing Behavior

// Independent timing (classic behavior) - each toast dismisses independently
await toastManager.showToast<String>(
  context,
  ToastConfig(
    toastType: ToastType.info,
    platformType: PlatformDetector.currentPlatform,
    message: 'Independent timing toast',
    timingBehavior: ToastTimingBehavior.independent,
    duration: const Duration(seconds: 3),
  ),
);

// Dependent timing (new feature) - older toasts pause when newer ones appear
await toastManager.showToast<String>(
  context,
  ToastConfig(
    toastType: ToastType.success,
    platformType: PlatformDetector.currentPlatform,
    message: 'Dependent timing toast',
    timingBehavior: ToastTimingBehavior.dependent, // Default
    duration: const Duration(seconds: 5),
  ),
);

// Multiple toasts with dependent timing
for (int i = 1; i <= 3; i++) {
  await toastManager.showToast<String>(
    context,
    ToastConfig(
      toastType: ToastType.warning,
      platformType: PlatformDetector.currentPlatform,
      message: 'Toast #$i - will pause when newer toast appears',
      timingBehavior: ToastTimingBehavior.dependent,
      duration: const Duration(seconds: 4),
    ),
  );
}
// Only the topmost toast will actively count down, others pause until visible

Advanced Usage #

Platform Detection & Responsive Design #

// Get current platform
final platformType = PlatformDetector.currentPlatform;

// Get responsive breakpoint
final breakpoint = ResponsiveBreakpoint.fromWidth(
  MediaQuery.of(context).size.width,
);

// Create responsive configuration
final responsiveConfig = ResponsiveConfig(
  breakpoint: breakpoint,
  maxWidth: breakpoint.isDesktop ? 600 : double.infinity,
  padding: breakpoint.isMobile
    ? const EdgeInsets.all(16)
    : const EdgeInsets.all(24),
);

Queue Management #

// Get queue status
final dialogQueue = DialogQueueManager.instance;
final snackbarQueue = SnackbarQueueManager.instance;
final toastQueue = ToastQueueManager.instance;

// Monitor queue changes
dialogQueue.stateStream.listen((dialogState) {
  print('Dialog state: ${dialogState.status}');
});

// Clear queues
await dialogQueue.clearQueue();
await snackbarQueue.clearQueue();
await toastQueue.clearQueue();

Debug Mode #

// Enable debug logging
AdaptiveDialogManager.instance.enableDebugMode();
AdaptiveSnackbarManager.instance.enableDebugMode();
AdaptiveToastManager.instance.enableDebugMode();

// View queue status
final dialogStatus = DialogQueueManager.instance.getQueueStatus();
print('Active dialogs: ${dialogStatus.activeCount}');
print('Pending dialogs: ${dialogStatus.pendingCount}');
