Changing focus from one text field to the next in Flutter

Question

I have two textFormField widgets. Once the user has completed the first text field I would like to focus on the next textField. Is there a way to do

Answer 1

This is how I did it:

  var _focusNodes = List.generate(6, (index) => FocusNode()));

And in the TextFormField:

  TextFormField(
    focusNode: _focusNodes[i],
    maxLines: 1,
    textInputAction: TextInputAction.next,
    onChanged: (text) {
      if (i < _controllers.length) {
        if (text.isEmpty)
          _focusNodes[i - 1].requestFocus();
        else
          _focusNodes[i + 1].requestFocus();
      }
    },
  ),
