TextField causing assertion errors on hot reload

[mdebbar]

Steps to Reproduce

import 'package:flutter/material.dart';

void main() => runApp(HelloWorld());

Widget field(String placeholder) {
  return Theme(
    data: ThemeData(textSelectionColor: Colors.orange.shade200),
    child: TextField(
      textAlign: TextAlign.center,
      controller: TextEditingController(text: placeholder),
    ),
  );
}

class HelloWorld extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: DefaultTextStyle.merge(
          style: const TextStyle(fontSize: 10),
          child: ListView(
            children: <Widget>[
              field('Cyan'),
              field('Orange'),
              field('Thick Rounded Cursor'),
            ],
          ),
        ),
      ),
    );
  }
}

1. Run the above app.
2. Change textAlign to TextAlign.start.
3. Hot reload will throw assertions.

Info

• This is from flutter master (currently at 7e22b5f).
• I'm running the app using VS Code (which does hot reload on save).
