ScopeProvider<SF extends StatefulWidget, BS extends BlocState, BL extends Bloc<BlocEvent, BS> , SC extends ScopeController<BL> > class
abstract
ScopeProvider is an abstract class that acts as a base for any StatefulWidget that wants to provide a ScopeController, Bloc, and listen to state changes.
It takes four generic parameters:
- SF: The type of StatefulWidget.
- BS: The type of BlocState (the state managed by the Bloc).
- BL: The type of Bloc that handles BlocEvent and emits BlocState.
- SC: The type of ScopeController that creates or manages the Bloc.

Methods
-
activate(
) → void -
Called when this object is reinserted into the tree after having been
removed via deactivate.
inherited
-
build(
BuildContext context) → Widget -
Describes the part of the user interface represented by this widget.
override
-
createController(
) → SC - Method that subclasses must implement to create their specific ScopeController.
-
deactivate(
) → void -
Called when this object is removed from the tree.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
didChangeDependencies(
) → void -
Called when a dependency of this State object changes.
inherited
-
didUpdateWidget(
covariant SF oldWidget) → void -
Called whenever the widget configuration changes.
inherited
-
dispose(
) → void -
Called when this object is removed from the tree permanently.
inherited
-
initState(
) → void -
Called when this object is inserted into the tree.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onBuild(
BuildContext context) → Widget - Abstract method for building the widget's UI. It will be wrapped inside a BlocListener and BlocBuilder to react to state changes and rebuild the UI.
-
onListen(
BuildContext context, BS state, SC controller) → void - Callback method that subclasses can override to respond to Bloc state changes. This is called when the BlocListener detects a new state.
-
reassemble(
) → void -
Called whenever the application is reassembled during debugging, for
example during hot reload.
inherited
-
setState(
VoidCallback fn) → void -
Notify the framework that the internal state of this object has changed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringShort(
) → String -
A brief description of this object, usually just the runtimeType and the
hashCode.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
Static Methods
-
of<
T extends ScopeController< (Bloc< >BlocEvent, BlocState> >BuildContext context, {bool listen = true}) → T - Static helper method that retrieves the ScopeController of type T from the widget tree. It uses the InheritedWidget pattern to locate the nearest _ScopeInherited widget, which contains the controller.
