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 adelay
.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
-
resetBloc(
) → void -
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 everyduration
.inherited -
toString(
) → String -
A string representation of this object.
inherited
-
