Pub

A package that makes shared_preferences easier to use, This package is built with bloc, shared_preferences

Usage #

  • Initialize bloc
var sharedPreferences = await SharedPreferences.getInstance();
// Build PreferenceBloc with manage preference in bloc
var preferenceBloc = PreferenceBloc(
  sharedPreferences: sharedPreferences,
  usagePreferences: [
    Preference<int>(
      key: 'counter',
      initValue: 0,
    ),
  ],
);
  • Provide PreferenceBloc with BlocProvider
void main() async {
  var sharedPreferences = await SharedPreferences.getInstance();
  runApp(MyApp(
    preferenceBloc: PreferenceBloc(
      sharedPreferences: sharedPreferences,
      usagePreferences: [
        Preference<int>(
          key: 'counter',
          initValue: 0,
        ),
      ],
    ),
  ));
}

class MyApp extends StatelessWidget {
  final PreferenceBloc preferenceBloc;

  MyApp({@required this.preferenceBloc});

  @override
  Widget build(BuildContext context) {
    return BlocProvider<PreferenceBloc>(
      bloc: preferenceBloc,
      child: MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          primarySwatch: Colors.blue,
        ),
        home: MyHomePage(title: 'Flutter Demo Home Page'),
      ),
    );
  }
}
  • Use preferences in widget with BlocBuilder
@override
Widget build(BuildContext context) {
  return BlocBuilder<PreferenceEvent, PreferenceState>(
    bloc: BlocProvider.of<PreferenceBloc>(context),
    builder: (BuildContext context, PreferenceState state) {
      var counter = state.preferences['counter'].value;
      return Text(count.toString());
    };
  );
}
  • Use preferences in widget without BlocBuilder
var prefCounter = preferenceBloc.getPreference(Preference<int>(
  key: "counter",
  initValue: 0,
));

print(prefCounter.value);

// or

var prefTypedCounter = preferenceBloc.getTypePreference<int>(
  key: "counter",
  initValue: 0,
);

print(prefTypedCounter.value);
