TextFieldState class

Maintains a TextEditingController and a FocusNode for a State and its Widgets.

Just pass controller and/or focusNode to your TextField or TextFormField and be notified via the *Changed callbacks.

Call update() during State.didUpdateWidget() if your state's widget has a controller or focusNode. Also call it during State.initState() if the TextFieldState instance was constructed before initState().

Don't forget to call dispose() from State.dispose()!

Constructors

TextFieldState({_TextChanged? textChanged, _FocusChanged? focusChanged, _FocusChanged? primaryFocusChanged, String? text, TextEditingController? controller, FocusNode? focusNode})
controller, focusNode, and text are from the state's widget, if applicable. They are provided here for convenience instead of having to call update() after construction.
