Automatically scroll multiline TextFormField when it extends the maxLines attribute


Asked by Rainer W on April 11, 2017 (source).

I'm implementing a TextFormField with the maxLines attribute set to 3. How can I make the TextFormField scroll down once the user starts with his fourth line? At the moment the cursor is just not visible anymore until the user scrolls down by hand. Is there a way to do this automatically?

This behaviour is actually featured in the flutter_gallery app in the 'Text fields' example. Just type a long text to the 'Live story' input until it reaches the fourth line.
The important parts of my code actually look like this:

import 'package:flutter/material.dart';

class TextFormFieldDemo extends StatelessWidget {
  Widget build(BuildContext context) {
    return new Scaffold(
      body: new Form(
        child: new TextFormField(
          maxLines: 3,

So far I have found no workaround for this issue.
This issue affects both iOS and android.

This appears to be a missing feature in the Flutter Framework, I've filed a bug to get it resolved:
