Error
Using hover run
to run my application. The text is garbled (looks like a corrupted texture). If I remove the texture, everything works fine. Gif Texture example is picked from examples.
I have a minimal repro in the example code:
import 'package:flutter/foundation.dart'
show debugDefaultTargetPlatformOverride;
import 'package:flutter/material.dart';
void main() {
debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia;
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'go-flutter Texture API',
theme: ThemeData(
// If the host is missing some fonts, it can cause the
// text to not be rendered or worse the app might crash.
fontFamily: 'Roboto',
primarySwatch: Colors.blue,
),
home: Scaffold(
appBar: AppBar(
title: Text('Texture Examples'),
),
body: Center(
child: Row(
crossAxisAlignment: CrossAxisAlignment.stretch,
children: <Widget>[
Expanded(
flex: 2,
child: Container(
decoration: BoxDecoration(
border: Border(right: BorderSide(width: 4))),
child: Text(
"Hello world",
style: TextStyle(fontSize: 50),
))),
Expanded(
flex: 2,
child: Container(
decoration: BoxDecoration(
border: Border(right: BorderSide(width: 4))),
child: Text(
"Hello world",
style: TextStyle(fontSize: 50),

Expanded(
flex: 8,
child: Column(
children: <Widget>[
ConstrainedBox(
constraints: BoxConstraints.tight(Size(640, 480)),
// hard-coded to 2
// (Not the best practice, let go-flutter generate this ID
// and send it back to the dart code using platform
// messages)
child: Texture(textureId: 2),
),
Text(
'Right Column: ',
style: TextStyle(fontSize: 40.0),
maxLines: 2,
),
],
),
),
],
),
),
),
);
}
}
I'd love to know if this issue is also reproducible on AOT: https://github.com/go-flutter-desktop/hover/pull/147
This issue might come from the non-main-call to https://github.com/go-flutter-desktop/go-flutter/blob/master/texture.go#L26
But could also be a flutter/engine issue.
