Methods

addOverlay(Widget overlay) → void

inherited
addPersistentFrameCallback(FrameCallback callback) → void

inherited
addPostFrameCallback(FrameCallback callback) → void
Registers a callback that is invoked once at the end of the next frame.
inherited
addShutdownCallback(ShutdownCallback callback) → void
Registers a callback to be invoked during shutdown.
inherited
attachRootWidget(Widget app) → void
Attaches the given app as the root widget without starting signal handlers.
inherited
disposeServices() → void
Disposes the keyboard and other platform services.
inherited
handleFrame() → void
Called once per frame to dispatch persistent and post-frame callbacks.
inherited
initializeServices() → void
Initializes the keyboard and other platform services.
inherited
initInstances() → void
Called during construction to initialize binding singletons.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paintElement(Element element) → void

inherited
scheduleFrameWithClear() → void

inherited
shutdown() → void
