Rather than this test, can we just add a golden test for this?
Just pump a simple/hello world app, use the screenshot method, and use the Skia gold comparison logic to compare it.

Sure, I can do that. Wouldn't it be clearer that we're specifically asserting for the RepaintBoundary by doing it in code here though?

Sure, but I think the idea is that we care if the screen shot works, and we don't particularly care where a repaint boundary is :)

That makes sense. I couldn't quite figure out how to get matchesGoldenFile to work with Skia gold though (following https://github.com/flutter/flutter/wiki/Writing-a-golden-file-test-for-package%3Aflutter). cc @Piinks - is the Skia golden integration supported for non-package:flutter packages like this? If not I can just check in the png into the tests/ directory alongside this test, but not sure if that's the best practice for this repo.

The Skia Gold integration does not currently work outside of the flutter package, no. It is set up with the flutter_test_config.dart in flutter/test. Maybe we can expand it? Not sure if there will be more integration tests requiring Skia support.

(PR triage) Are there still plans for this PR? |

Let's land this as is for now and have a bug to track getting golden image support for it. |

Sorry, I wasn't able to find time to figure out the Skia Gold integration, filed #72045 for that, thanks! |
Description
Workaround for #66006, where screenshots have incorrect bounds. Let me know if otherwise, but adding it here instead of
LiveTestWidgetsFlutterBindingsince taking screenshots doesn't seem like a common use case for that.Tests
I added the following tests:
