builders library

Classes

BlocBuilder<C extends Cubit<S>, S>

{@endtemplate}

BlocBuilderBase<C extends Cubit<S>, S>

Base class for widgets that build themselves based on interaction with a specified cubit.

BlocConsumer<S extends Cubit<V>, V>

BlocConsumer exposes a builder and listener in order react to new states. BlocConsumer is analogous to a nested BlocListener and BlocBuilder but reduces the amount of boilerplate needed. BlocConsumer should only be used when it is necessary to both rebuild UI and execute other reactions to state changes in the cubit.

Builders

Consumer<T extends ChangeNotifier>

Selector<T extends ChangeNotifier, D>

Typedefs

BlocBuilderCondition<S> = bool Function(S previous, S current)

Signature for the buildWhen function which takes the previous state and the current state and is responsible for returning a bool which determines whether to rebuild BlocBuilder with the current state.

BlocWidgetBuilder<S> = Widget Function(BuildContext context, S state)

Signature for the builder function which takes the BuildContext and state and is responsible for returning a widget which is to be rendered. This is analogous to the builder function in StreamBuilder.

ProviderReturn<T> = T? Function<T extends Object>()
