The OrientationBuilder value and the MediaQuery's orientation value differ ? #177435
Description
Steps to reproduce
Hello! We deeply appreciate your ongoing development, contributions, and above all, maintenance of the excellent Flutter software.
We are using Flutter and find most aspects to be very comfortable and outstanding.
Recently, while implementing an application, we encountered the following case. We apologize for the inconvenience during your busy schedule, but we would be grateful if you could review this issue.
- Prepare a foldable Android device. (Here, we prepared an emulator for the Pixel 9 Pro Fold 36.1)
- When using OrientationBuilder with the foldable device unfolded, the results returned by MediaQuery will be inconsistent.
Expected results
We understand that OrientationBuilder depends on the orientation from the parent widget tree, but this creates inconsistencies with MediaQuery. We need to discuss either renaming the “OrientationBuilder” property in one of these mechanisms or building an entirely separate OrientationBuilder using MediaQuery values.
Actual results
Using OrientationBuilder with a folded device results in inconsistent MediaQuery outputs. While the results may be correct, I feel it would be better to either rename it or provide a dedicated widget like DeviceOrientationBuilder.
Code sample
OrientationBuilder
import 'package:flutter/material.dart';
class Orientation0 extends StatelessWidget {
const Orientation0({super.key});
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Flutter OrientationBuilder'),
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
),
body: OrientationBuilder(
builder: (context, orientation) {
return Center(
child: Text(
orientation == Orientation.portrait ? 'portrait' : 'landscape',
style: Theme.of(context).textTheme.headlineLarge,
),
);
},
),
);
}
}
MediaQuery.of(context).orientation
import 'package:flutter/material.dart';
class Orientation1 extends StatelessWidget {
const Orientation1({super.key});
@override
Widget build(BuildContext context) {
final orientation = MediaQuery.of(context).orientation;
return Scaffold(
appBar: AppBar(
title: const Text('Flutter MediaQuery orientation'),
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
),
body: Center(
child: Text(
orientation == Orientation.portrait ? 'portrait' : 'landscape',
style: Theme.of(context).textTheme.headlineLarge,
),
),
);
}
}
