How do I supply an initial value to a text field?

Question

I\'d like to supply an initial value to a text field and redraw it with an empty value to clear the text. What\'s the best approach to do that with Flutter\'s APIs?

Answer 1

class _YourClassState extends State {
  TextEditingController _controller = TextEditingController();

  @override
  void initState() {
    super.initState();
    _controller.text = 'Your message';
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.white,
      child: TextFormField(
        controller: _controller,
        decoration: InputDecoration(labelText: 'Send message...'),
      ),
    );
  }
}
