Methods

canClose() → bool
Whether the BloC can be closed. Override this method to prevent the BloC from closing.
inherited
close() → void
Closes the BloC. This method should be called when the BloC is no longer needed.
inherited
debounce(BlocDebounceCallback<BlocEvent> function, {Duration delay = const Duration(milliseconds: 300)}) → BlocDebounceCallback<BlocEvent>
Creates a debounced function that only invokes function after a delay.
inherited
getInitialState() → S
Tries to retreive the initial BloC's state.
inherited
initState() → S
Optional callback method to initialize the BloC's state.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setState(S nextState) → void
Set the BloC state.
inherited
throttle(BlocThrottleCallback<BlocEvent> function, {Duration duration = const Duration(milliseconds: 300)}) → BlocThrottleCallback<BlocEvent>
Creates a throttled function that only invokes function at most once per every duration.
inherited
toString() → String
A string representation of this object.
inherited
transformError(dynamic error, StackTrace stackTrace) → BlocError?
Transforms the error before it is emitted.

Operators

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