Text selection issue

text_selection_test.dart

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  final _controller = TextEditingController(text: 'Please select me!');

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Bug',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: Scaffold(
        appBar: AppBar(
          title: Text("Flutter Bug"),
          actions: [
            IconButton(
              icon: Icon(Icons.select_all_rounded),
              onPressed: () {
                _controller.selection = TextSelection(baseOffset: 7, extentOffset: 13);
              },
            )
          ],
        ),
        body: Center(
          child: TextField(
            controller: _controller,
          ),
        ),
      ),
    );
  }
}

Hi @justin,
While working on this proposal for text selection, I found out that this piece of code does not show the selection handler, I fear it is a bug. If it is a bug let me know to fix it!
