This PR doesn't include implementation of InheritedModel for Theme.

packages/flutter/test/material/theme_test.dart

    await tester.pump(const Duration(seconds: 1));

-    expect(Theme.of(tester.element(find.text('menuItem'))).brightness, equals(Brightness.dark));
+    expect(Theme.brightnessOf(tester.element(find.text('menuItem'))), equals(Brightness.dark));


I would propose to not do this change in this PR, we can probably do all the ThemeData.brightness changes in a follow up PR, after this one lands. (which probably makes it a bit easier to review)

Instead, I would test the behavior of brightnessOf / maybeBrightnessOf in separate tests:

brightnessOf returns the correct brightness if only a MediaQuery is provided

brightnessOf returns the correct brightness if both a MediaQuery & ThemeData are provided

brightnessOf throws if neither a MediaQuery or ThemeData is provided

maybeBrightnessOf returns the correct brightness if only a MediaQuery is provided

maybeBrightnessOf returns the correct brightness if both a MediaQuery & ThemeData are provided

maybeBrightnessOf returns null if neither a MediaQuery or ThemeData is provided

I will file a follow up issue to do the former sparately.

Sure, let me create another test which just verify that Theme.brightnessOf works in all scenario

@navaronbracke I don't think scenario 3 and 6 can be produced, because in testing media query always return platform brightness.

For these tests I would just pump a widget with the WidgetTester:

Only pumps a MediaQuery widget with a Builder as child (to get the context for the brightness test)

Pumps both a MediaQuery & a Theme widget, with a Builder as child

Pumps only a Builder widget and never pumps a MediaQuery or Theme widget

Cases 4-6 are variations, but use the other method.

You should be able to give the MediaQuery a custom MediaQueryData, to force the brightness?

Yes, MediaQuery takes data as input.

I would use a SizedBox, instead of a Container to make the tests a little lighter.

Should the MediaQuery be above the Theme, for consistency with the real widget tree in MaterialApp?

Minor docs correction and a suggestion for some missing tests.

Suggested change

I had a look at the implementation of https://api.flutter.dev/flutter/widgets/MediaQuery/platformBrightnessOf.html

and it returns Brightness.light instead of throwing if there is no MediaQuery.
So you can remove the phrase that says it throws.

packages/flutter/test/material/theme_test.dart

navaronbracke

Some minor docs adjustments, to match the actual behavior of the method that is used, along with a clarification for one test.

+  /// See also:

Since platformBrightnessOf does not throw, but returns a default, I think we can tweak the wording here.

Suggested change

/// [MediaQuery] exists, instead of throwing.

/// [MediaQuery] exists.

Can we remove this phrase? Currently it says returns null twice

Same tweak here, since that method does not throw.

Suggested change

/// * [brightnessOf], which throws if no valid [InheritedTheme] or

/// * [brightnessOf], which returns a default value if no valid [InheritedTheme] or

We need to prevent the View from adding the MediaQuery here, otherwise there is an implicit MediaQuery

Suggested change

await tester.pumpWidget(const SizedBox());

// Prevent the implicitly added View from adding a MediaQuery

await tester.pumpWidget(

RawView(view: FakeFlutterView(tester.view, viewId: 77), child: const SizedBox()),

wrapWithView: false,

@rkishan516 While to me this PR looks good now, I will have to defer to people on the framework team for a review / explicit approval. So you will have to be patient a little :)

See https://github.com/flutter/flutter/blob/master/docs/contributing/Tree-hygiene.md#when for more info on the review process.

Sure and Thanks for helping @navaronbracke.

QuncCccccc

Can we use Theme.of(context).brightness to detect the brightness?

navaronbracke · 2025-03-14T19:46:35Z

That is how you would do this today. However, this PR aims to make it explicit, using a named method, and is a step towards eventually making Theme an InheritedModel. The latter is the main reasoning behind this change.

dkwingsmt · 2025-03-14T20:05:26Z

@navaronbracke I'm not familiar with this work, but is there an issue tracking our progress (and discussions, if any) towards making Theme an InheritedModel?

navaronbracke · 2025-03-14T20:10:32Z

@nate-thegrate made a design doc that talks about this a little in https://docs.google.com/document/d/1MfU6gkgIgXCxa5E25sPYuAP5Bmgehyl3Hk7yDH24zl0/edit?tab=t.0

dkwingsmt · 2025-03-14T20:25:54Z

I've asked @MitchellGoodwin and it seems the conversation didn't reached a point were a decision was made. Although I agree with the motivation of the work, I think it'd be better not to move forward until we have agreed on the exact design and plan.

If you would like to drive this project, you can start by writing a more detailed design doc with thorough planning and introduction, and we can seek comments or even host a Dash forum for discussion.
