Methods

$configureLifeCycle() → void
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
override
onEndScroll() Future<void>
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
override
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
onTopScroll() Future<void>
toString() String
A string representation of this object.
