Answer 1

You are do something like following:

TextEditingController _controller = new TextEditingController();

@override
Widget build(BuildContext context) {
...
    child: TextField(controller: _controller),
}

You can later use the _controller to set the value of Textfield like this:

_controller.text = "New Text Value";

Does this solve your problem?
