Accessing state of Statefull Widget

Question

I have a situtation where i would like to access to text of a text controller, from the Widget part of a statefull widget.

So what i would like to do is is write a method getText() that returns the current text in my _textController.

I know how to do this from the other way around. If i need to get data from my widget from the State part of my widget is use "widget.", but i dont know how to do this the other way around.

class MyTextWidget extends StatefulWidget { String getText() { // how can i access the _textController.text from here? } @override _MyTextWidgetState createState() => _MyTextWidgetState(); } class _MyTextWidgetState extends State<MyTextWidget> { final TextEditingController _textController = TextEditingController(); _MyTextWidgetState(); @override void dispose() { _textController.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Container( padding: EdgeInsets.all(2.0), child: TextField( controller: _textController, key: ValueKey('MyTextWidgetinput_Key'), maxLines: null, autofocus: true, keyboardType: TextInputType.multiline, decoration: InputDecoration( border: OutlineInputBorder( borderRadius: const BorderRadius.all(Radius.circular(15.0))), ), )); } }

Simply move it up and access it in your state class using widget._textController:

class MyTextWidget extends StatefulWidget { final TextEditingController _textController = TextEditingController(); String getText() { _textController.text // do something with it // how can i access the _textController.text from here? } @override _MyTextWidgetState createState() => _MyTextWidgetState(); } class _MyTextWidgetState extends State<MyTextWidget> { _MyTextWidgetState(); @override void dispose() { widget._textController.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Container( padding: EdgeInsets.all(2.0), child: TextField( controller: widget._textController, key: ValueKey('MyTextWidgetinput_Key'), maxLines: null, autofocus: true, keyboardType: TextInputType.multiline, decoration: InputDecoration( border: OutlineInputBorder( borderRadius: const BorderRadius.all(Radius.circular(15.0))), ), )); } }
