j'ai trouvé la solution en changeant les données dans injection_container.dart

sl.registerSingletonAsync( () async => SharedPreferences.getInstance());

sl.registerSingletonWithDependencies( () => TriviaNumberLocalDataSourceImpl(sharedPreferences: sl()), dependsOn: [SharedPreferences]);

Et dans main.dart

return FutureBuilder( future: sl.allReady(), builder: (BuildContext context, AsyncSnapshot snapshot) { if (snapshot.hasData) { return MaterialApp( title: "Number Trivia", theme: ThemeData( primaryColor: Colors.green.shade800, accentColor: Colors.green.shade600), home: TriviaNumberPage(), ); } else { return Center( child: CircularProgressIndicator(), ); } });
