Unhandled Exception: MissingPluginException when running Flutter app with sqflite

Question

I'm trying to use SQLite database using the sqflite plugin. Running the app below results in Unhandled Exception: MissingPluginException error. Here's my code:

main.dart :

...
late final Database database;

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  database = await openDatabase(
    join(await getDatabasesPath(), 'mydb.db'),
    version: 1,
    onCreate: (db, version) {
      return db.execute('CREATE TABLE config(key TEXT PRIMARY KEY, value TEXT)');
    },
  );

  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      title: 'MyApp',
      initialRoute: '/',
      onGenerateRoute: (settings) => onGenerateRoute(settings),
      onUnknownRoute: pageNotImplementedRoute,
    );
  }
}

Route? onGenerateRoute(RouteSettings settings) {
  ...
}

Route pageNotImplementedRoute(RouteSettings settings) {
  return MaterialPageRoute<void>(...);
}

Here's the output from the run:

Anyone has any idea what's wrong?

Answer 1

This error is just because the SQFLite dependency not get it's package. you should follow this steps. It's Work for me...

1. flutter clean
2. File > Invalide caches & Restart
3. flutter pub get

And you will get your desired outcome.!
