Hydrated
Hydrated provides a BehaviorSubject that automatically persists to Flutter’s local storage and hydrates on creation!
Easy to consume
All values are persisted with shared_preferences and restored with automatic hydration.
final count$ = HydratedSubject<int>("count", seedValue: 0);
/// count$ will automagically be hydrated with 42 next time it is created
count$.add(42);
Ready for BLoC
class HydratedBloc {
final _count$ = HydratedSubject<int>("count", seedValue: 0);
ValueObservable<int> get count$ => _count$.stream;
Sink<int> get setCount => _count$.sink;
dispose() {
_count$.close();
}
}
Supports simple types and serialized classes
We support all shared_preferences types.
int
double
bool
String
List<String>
final count$ = HydratedSubject<int>("count");
We also support serialized classes with hydrate and persist arguments.
final user$ = HydratedSubject<User>(
"user",
hydrate: (String s) => User.fromJSON(s),
persist: (User user) => user.toJSON(),
);
Reliable
Hydrated is mock tested with all supported types and is dogfooded by its creator.
