Properties

cachedValue → T?
Useful for using as initialValue in StreamBuilder.
no setterinherited
defaultCreator → (T Function()?)
finalinherited
fromJson ↔ FromJson<T>
getter/setter pairinherited
hashCode → int
The hash code for this object.
no setterinherited
name → String
Name of the store (used as file name for the .json file)
finalinherited
onValueChanged → Stream<T>
Stream which will receive a new notification on every save call.
no setteroverride
onValueChangedAndLoad → Stream<T>
Stream with the current value as first event, concatenated with onValueChanged.

Methods

delete() → Future<void>
inherited
dispose() → Future<void>
Removes this store from memory. Probably not really useful in a real world app and should not be used outside of testing.
inherited
load() → Future<T>
Loads and deserializes data from storage. It is safe to be called multiple times. Subsequent calls will return the same future. If loaded, the cached value will be returned. (cachedValue). If file does not exist the default value (defaultCreator) will be returned.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onValueChangedOrDefault(Future<T> defaultValue) → Stream<T?>
inherited
save(T value) → Future<void>
inherited
toString() → String
A string representation of this object.
inherited
update(T updater(T data)) → Future<T>
Convenience method which allows simple updating of data. The updater gets the current value as parameter and is expected to return a copy with the new values which will be persisted afterwards.
override

Operators

operator ==(Object other) → bool
The equality operator.
