TextInputBinding class
Inheritance
Mixed in types
Methods
addObserver (WidgetsBindingObserver observer → void
Registers the given object as a binding observer. Binding
observers are notified when various application events occur,
for example when the system locale changes. Generally, one
widget in the widget tree registers itself as a binding
observer, and converts the system state into inherited widgets.
inherited

Adds a persistent frame callback.
inherited

Schedule a callback for the end of this frame.
inherited
addSemanticsEnabledListener (VoidCallback listener → void
Adds a listener to be called when semanticsEnabled changes.
inherited
addTimingsCallback (TimingsCallback callback → void
Add a TimingsCallback that receives FrameTiming sent from
the engine.
inherited

Called after deferFirstFrame to tell the framework that it is ok to
send the first frame to the engine now.
inherited

SemanticsNode .
inherited
postEvent (String eventKind , Map <String dynamic > eventData → void
