BlocSideEffectListenerBase<B extends SideEffectProvider<C>, C> class abstract

Base for widgets that listen to side effect emits in a specified bloc.

A BlocSideEffectListenerBase is stateful and maintains the side effect subscription. The type of the side effect and what happens with each side effect emit is defined by sub-classes.

Properties

bloc → B?
The bloc whose side effect will be listened to. Whenever the bloc's side effect emits, listener will be invoked.
final
child → Widget?
The widget which will be rendered as a descendant of the BlocSideEffectListenerBase.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
listener → BlocWidgetSideEffectListener<C>
The BlocWidgetListener which will be called on every side effect emit. This listener should be used for any code which needs to execute in response to a side effect emit.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
