A Cubit that enables state emission from one method call at a time.
If multiple state-emitting method calls are running at the same time, then this can prevent old method calls from emitting states in favor of the new method call states.
Constructors
- DistinctCubit(S initialState)
- A Cubit that enables state emission from one method call at a time.

- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
addError(
Object error, [StackTrace? stackTrace]) → void -
Reports an
error
which triggers onError with an optional StackTrace.inherited -
close(
) → Future< void> -
Closes the instance.
This method should be called when the instance is no longer needed.
Once close is called, the instance can no longer be used.
inherited
-
distinctEmit(
int actionToken, S stateCallback()) → S? -
Updates the Cubit's state based on the
stateCallback
. -
emit(
S state) → void -
Do not use directly. Instead, use distinctEmit.
override
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onChange(
Change< S> change) → void -
Called whenever a
change
occurs with the givenchange
. Achange
occurs when a newstate
is emitted. onChange is called before thestate
of thecubit
is updated. onChange is a great spot to add logging/analytics for a specificcubit
.inherited -
onError(
Object error, StackTrace stackTrace) → void -
Called whenever an
error
occurs and notifies BlocObserver.onError.inherited -
requestNewActionToken(
) → int - Generates a new action token.
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
Constants
- initialActionToken → const int
- The initial action token.
