TextField: Bug with Dialog #37798
Description
Internal: b/147671610
I'm having a bug with the TextField not showing the selection menu (I want to paste text) if used with a modal, like for example a Dialog. This just happens when it is used with a TextEditingController, if you just comment the line 'controller: _controller,' it is working as expected.
Steps to Reproduce
Use the following minimal example to test the bug. Click OPEN and long-pressed the TextField, then the selection menu will appear. Dismiss the modal by pressing outside, then click again OPEN and repeat the operation: the selection menu doesn't appear.
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
const MyApp();
@override
Widget build(BuildContext context) {
return MaterialApp(
theme: ThemeData(),
title: 'Text Field Test',
home: Home(),
);
}
}
class Home extends StatefulWidget {
@override
_HomeState createState() => _HomeState();
}
class _HomeState extends State<Home> {
TextEditingController _controller;
@override
void initState() {
super.initState();
_controller = TextEditingController();
}
@override
void dispose() {
_controller.dispose();
super.dispose();
}
void _showDialog(BuildContext context) {
showDialog<void>(
context: context,
builder: (_) => Dialog(
child: Container(
padding: const EdgeInsets.all(20),
child: TextField(
controller: _controller,
),
),
),
);
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("TextField Test"),
),
body: Center(
child: FlatButton(
child: Text("OPEN"),
onPressed: () => _showDialog(context),
),
),
);
}
}
