DataCubitBuilder<TDataBloc extends DataCubit<DataState<TFailure, TSuccess>, TFailure, TSuccess>, TFailure, TSuccess> class
Properties
-
bloc
→ TDataBloc?
-
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<DataState<TFailure, TSuccess>>
-
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<DataState<TFailure, TSuccess>>?
-
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
.

-
hashCode
