TextField throws error in production environment because it wrongly uses ancestor render boxes (will PR; with cause analyzed) #126312
Description
Hi thanks for the Flutter framework! However I am seeing this annoying bug in production environment :( Below are my analysis of bug cause, and I will PR soon.
Analysis of cause
Remark: I will try to explain it as clear as possible, so the explanation order is quite different from how I actually find this annoying bug.
Firstly, the reproduction ensures that the following stack trace is triggered (marked by <-----):
void didUpdateWidget(MyEditableText oldWidget) {
...
else if (oldWidget.readOnly && _hasFocus) {
_openInputConnection(); // <------
... void _openInputConnection() {
...
_updateSizeAndTransform(); // <------
... void _updateSizeAndTransform() {
if (_hasInputConnection) {
final Size size = renderEditable.size;
final Matrix4 transform = renderEditable.getTransformTo(null); // <------
...or, a screenshot if you like:
Now comes the problem: Theoretically, we are calling getTransformTo inside a didUpdateWidget. In other words, we are fetching information that is available only in/after layout-phase at the build-phase.
In normal cases, this may not be a problem, since we are inside didUpdateWidget, so we should already have done one build and thus there should be some (though possibly outdated) layout information.
However, consider the GlobalKey-triggered reparenting scenario. In the minimal reproducible sample code, as you can see, I am using a GlobalKey, and the didUpdateWidget is triggered when the TextField subtree is moved into a brand new location, i.e. as a child of the brand new FractionalTranslation.
Now comes the problem. The FractionalTranslation is just created, and thus it has not gone through the layout phase at all. Thus, when we are calling getTransformTo(), we will go through ancestors, including the RenderFractionalTranslation, and asks it to provide a transformation (applyPaintTransform). How can it provide one if it has not been laid out? Then the error is thrown.
Generalization of the bug: After understanding the cause, we can see that, not only FractionalTranslation, but any RenderObject that requires layout-phase information at its applyPaintTransform will cause the trouble.
P.S. This is just a minimal reproducible sample, and in production environment surely my widget tree is not this weird and artificial.
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
- Run app
- tap the text field (it is readOnly=true, so you will see it is highlighted, but keyboard not opened)
- tap the "toggle" button
- see error
Expected results
no error
Actual results
see error
Code sample
Code sample
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
const MyApp({super.key});
@override
State<MyApp> createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
final textFieldKey = GlobalKey();
var enable = false;
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(),
body: Column(
children: [
TextButton(
onPressed: () {
print('tap toggle');
setState(() => enable = !enable);
},
child: Text('toggle'),
),
enable
? FractionalTranslation(
translation: Offset(0.1, 0.1),
child: TextField(key: textFieldKey),
)
: TextField(key: textFieldKey, readOnly: true),
],
),
),
);
}
