Fixes #161687 Enables scrollable content within the sheet to work together with the dragging animation. Flutter: https://github.com/user-attachments/assets/3a9994e3-078a-410e-8288-95592713ab39 Native: https://github.com/user-attachments/assets/c0bd46fb-26f5-41a6-bf42-6c78c23ddf34 Fling when scrolling to the top vs fling when the scrollable content is already at the top https://github.com/user-attachments/assets/e934facc-36d2-4e81-9ccd-a3e9dd7b6201 When scrolling is enabled, then the sheet will no longer have a drag gesture recognizer over the sheet content, and will instead rely on the scrollable content to trigger the drag. A non-scrolling area can be wrapped with `CupertinoSheetDragArea` to put a drag gesture recognizer only on that area, convenient for navbars. See [cupertino_sheet.3.dart](https://github.com/flutter/flutter/pull/177337/files#diff-3df71aa5e6ddb6184007a85e847a9a4883515697b7014764e1978d240d72e0e1) for a full example. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [ ] All existing and new tests are passing.

Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed. <!-- Links --> [Contributor Guide]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md#overview [Tree Hygiene]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md [test-exempt]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md#tests [Flutter Style Guide]: https://github.com/flutter/flutter/blob/main/docs/contributing/Style-guide-for-Flutter-repo.md [Features we expect every widget to implement]: https://github.com/flutter/flutter/blob/main/docs/contributing/Style-guide-for-Flutter-repo.md#features-we-expect-every-widget-to-implement [CLA]: https://cla.developers.google.com/ [flutter/tests]: https://github.com/flutter/tests [breaking change policy]: https://github.com/flutter/flutter/blob/main/docs/contributing/Tree-hygiene.md#handling-breaking-changes [Discord]: https://github.com/flutter/flutter/blob/main/docs/contributing/Chat.md [Data Driven Fixes]: https://github.com/flutter/flutter/blob/main/docs/contributing/Data-driven-Fixes.md
Directory contents
The Dart files and golden master .expect files in this directory are used to
test the dart fix framework refactorings
used by the Flutter framework.
See the flutter/packages/flutter/lib/fix_data directory for the current package:flutter data-driven fixes.
To run these tests locally, execute this command in the flutter/packages/flutter/test_fixes directory.
dart fix --compare-to-golden
For more documentation about Data Driven Fixes, see https://dart.dev/go/data-driven-fixes#test-folder.
To learn more about how fixes are authored in package:flutter, see Data driven fixes.
When making structural changes to this directory
The tests in this directory are also invoked from external repositories. Specifically, the CI system for the dart-lang/sdk repo runs these tests in order to ensure that changes to the dart fix file format do not break Flutter.
See tools/bots/flutter/analyze_flutter_flutter.sh for where the tests are invoked.
When possible, please coordinate changes to this directory that might affect the
analyze_flutter_flutter.sh script.
