Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
beforeFirstRender() → void

inherited
forceRebuild() → void
Force a rebuild of the current page.
handleAction(Future<void> function(), {dynamic onError(dynamic error)?, String message = '', bool skipBusyState = false}) → Future<void>
Perform a future action, catching any exceptions which may occur. This also sets a isBusy flag while the action is being performed.
handleCancelBackGesture() → void
inherited
handleCommitBackGesture() → void
inherited
handleStartBackGesture(PredictiveBackEvent backEvent) → bool
