class abstract

A base page for widgets that use either a Bloc or a Cubit and hold no state of their own beyond the injected state manager.

Type Parameters:

B: The type of state manager (Bloc or Cubit) this page will use.

The delegate handles:

Dependency injection setup
Common bloc integration
Navigation setup
Loading overlay management

This is a StatefulWidget

It was previously a StatelessWidget carrying late final fields for its resolved dependencies. That is unsound: Flutter may reconstruct a widget on any parent rebuild, and the new instance resolves its own stateManager while the element tree keeps providing the one built for the element — so bloc.add(...) sent events to an instance nothing rendered. Resolution now lives in the State, which is what actually persists across rebuilds.

buildPage receives the state manager as an argument rather than reading a field, so what a page renders and what it sends events to cannot diverge. Subclasses may also declare const constructors again.

Methods

buildLoadingOverlay({required Widget child, String? loadingKey = LoadingKey.global, Widget? loadingWidget}) → Widget
buildPage(BuildContext context, B stateManager) → Widget: Builds the main content of the page.
buildPageListeners({required Widget child}) → Widget: Builds any additional bloc listeners.
buildPageLoading() → Widget: Builds the loading indicator widget.
createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<BasePageStatelessDelegate<B>>: Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.
