Answer 1

A widget that calls a callback whenever the user presses or releases a key on a keyboard.

A RawKeyboardListener is useful for listening to raw key events and hardware buttons that are represented as keys. Typically used by games and other apps that use keyboards for purposes other than text entry.

For text entry, consider using a EditableText, which integrates with on-screen keyboards and input method editors (IMEs).

 const RawKeyboardListener({
Key key,
@required FocusNode focusNode,
@required ValueChanged onKey,
@required Widget child
})

Creates a widget that receives raw keyboard events.

Implementation

const RawKeyboardListener({
  Key key,
  @required this.focusNode,
  @required this.onKey,
  @required this.child,
}) : assert(focusNode != null),
     assert(child != null),
     super(key: key);
