🛠️ Setup #

1. Wrap your app with ProviderScope and EasyLocalization

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await EasyLocalization.ensureInitialized();

  runApp(
    ProviderScope(
      child: EasyLocalization(
        supportedLocales: const [Locale('en')],
        path: 'assets/translations',
        fallbackLocale: const Locale('en'),
        child: const MyApp(),
      ),
    ),
  );
}

2. Register context after StyledToast is mounted

class MyApp extends ConsumerWidget {
  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return StyledToast(
      locale: context.locale,
      child: MaterialApp(
        home: ToastContextRegistrar(
          child: const HomePage(),
        ),
      ),
    );
  }
}

class ToastContextRegistrar extends ConsumerStatefulWidget {
  final Widget child;
  const ToastContextRegistrar({required this.child});

  @override
  ConsumerState<ToastContextRegistrar> createState() => _ToastContextRegistrarState();
}

class _ToastContextRegistrarState extends ConsumerState<ToastContextRegistrar> {
  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((_) {
      ref.read(toastControllerProvider.notifier).registerContext(context);
    });
  }

  @override
  Widget build(BuildContext context) => widget.child;
}

✅ Usage #

In any widget or service:

showSuccess(ref, 'Operation successful');
showError(ref, 'Something went wrong!');
showWarning(ref, 'Be careful!');
showInfo(ref, 'This is an info message');

You don’t need to pass context — it’s already registered via Riverpod.

🌓 Dark Mode & Styling #

Toasts adapt automatically based on the theme. You can customize animations, padding, colors, border radius, etc., by editing ToastController._buildToastWidget(...).

🌐 Localization #

If you're using EasyLocalization, toast messages can be translated automatically:

showSuccess(ref, 'msg_operation_successful'.tr());

You can also configure whether a message should be treated as localized using the localized flag in show().

🧪 Testing & Debugging #

You can inspect the internal queue using:

final queue = ref.watch(toastControllerProvider);

Logs are printed during registration, deduplication, and toast display.

📦 Folder Structure #

• lib/riverpod_toast.dart: main export
• src/toast_controller.dart: Riverpod notifier with queue/dedupe logic
• src/toast_type.dart: enum for toast types
• src/toast_helpers.dart: exposed functions like showSuccess()

🔮 Coming Soon #

✅ ToastScope widget — auto-registers context with no boilerplate ✅ Actionable toasts — support for actions like UNDO, RETRY, etc. ✅ Global fallback to ScaffoldMessenger if overlay not available ✅ Adaptive styling hooks for Material 3 & platform UI ✅ Configuration builder for themes, durations, animation styles ✅ Optional ToastTheme override per toast ✅ Support for persistent toasts with dismiss buttons
