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.
inherited
changeModel<T>(Symbol key, T value) → void

Available on State<X>, provided by the StateExtension extension

Change the data of the model with the given key. Throws an assertion error if the model is read-only.
close([bool immediate = false]) → Future<void>
closeLater() → void
closeWithResult<X>([X? value]) → Future<void>
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 T oldWidget) → void
Called whenever the widget configuration changes.
inherited
dispose() → void
Called when this object is removed from the tree permanently.
inherited
find<T>() → T

Available on State<X>, provided by the StateExtension extension

Find the data of the given type from the context. Does not listen to the data changes.
findMessenger<T>() → T
