Just use:

textInputAction: TextInputAction.next: To move the cursor to the next field.

textInputAction: TextInputAction.done: To close the keyboard.

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Column(
      children: <Widget>[
        TextField(
          decoration: InputDecoration(hintText: 'TextField A'),
          textInputAction: TextInputAction.next, // Moves focus to next.
        ),
        TextField(
          decoration: InputDecoration(hintText: 'TextField B'),
          textInputAction: TextInputAction.next, // Moves focus to next.
        ),
        TextField(
          decoration: InputDecoration(hintText: 'TextField C'),
          textInputAction: TextInputAction.done, // Hides the keyboard.
        ),
      ],
    ),
  );
}
