CoreWidget class abstract

The base StatefulWidget for the Control framework.

It creates a CoreContext (its Element), which is the heart of the framework's state management and dependency injection system. All other control widgets (ControlWidget, SingleControlWidget, etc.) extend from this.

See also:

• CoreState, the state object for this widget.
• CoreContext, the element that manages the widget's lifecycle and dependencies.

Methods

createElement() → CoreContext

Creates a StatefulElement to manage this widget's location in the tree.

override

createState() → CoreState<CoreWidget>

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

init(CoreContext context) → void

A preliminary initialization method called by the CoreContext. This is a good place for mixins to hook into the initialization process.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onDependencyChanged(CoreContext context) → void

Called when a dependency of this widget changes. See State.didChangeDependencies for more information.

onDispose() → void

Called when the widget is being disposed.

onInit(Map args, CoreContext context) → void

Called once when the state is fully initialized and the context is available.

onUpdate(CoreContext context, CoreWidget oldWidget) → void

Called when the widget is updated with new configuration. See State.didUpdateWidget for more information.

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.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
