ActionBlocBuilder<B extends BlocBase<AsyncActionResult>> class

Inheritance

Constructors

ActionBlocBuilder({Key? key, B? bloc, WidgetBuilder? pendingBuilder, WidgetBuilder? waitingBuilder, FailedResultBuilder? failedBuilder, required WidgetBuilder builder, BlocBuilderCondition<AsyncActionResult>? buildWhen})

Properties

bloc → B?
The bloc that the BlocBuilderBase will interact with. If omitted, BlocBuilderBase will automatically perform a lookup using BlocProvider and the current BuildContext.
finalinherited
builder → BlocWidgetBuilder<AsyncActionResult>
The builder function which will be invoked on each widget build. The builder takes the BuildContext and current state and must return a widget. This is analogous to the builder function in StreamBuilder.
finalinherited
buildWhen → BlocBuilderCondition<AsyncActionResult>?
An optional buildWhen can be implemented for more granular control over how often BlocBuilder rebuilds. buildWhen should only be used for performance optimizations as it provides no security about the state passed to the builder function. buildWhen will be invoked on each bloc state change. buildWhen takes the previous state and current state and must return a bool which determines whether or not the builder function will be invoked. The previous state will be initialized to the state of the bloc when the BlocBuilder is initialized. buildWhen is optional and if omitted, it will default to true.
