(from offline review with@Piinks) these asserts (plus the delta assert) look valid. Are they related to this change specifically or just good to have generally? And can we add tests for them in either case?

I submitted the corresponding unit tests.
The assets are unrelated to this change. I just thought of an optimization that could be added when I saw the code, as I noticed that theFlutter documentation encourages us to use assertions.
| assert(maxScrolls>0); |
Use asserts liberally to detect contract violations and verify invariants
assert() allows us to be diligent about correctness without paying a performance penalty in release mode, because Dart only evaluates asserts in debug mode.
However, I didn't realize that adding asserts also requires corresponding unit tests. Maybe in the future, I should try to submit code that is only related to the issue at hand.

The assertions seem valid to add, but maybe in a subsequent PR so it's easier to track and review.
Unit tests for them shouldn't be too difficult to add as well. Consider thisPR that only added assertions for some test inspiration.

I have reverted the asserts and the corresponding tests, and I may submit a new PR later.

There are quite a lot of google testing failures. I wonder if there are things in thedrag method that this refactor doesn't replace?

I'm guessing the tests this affects in Google were written to expect the behavior written in the bug. This might be difficult to change since it breaks existing test logic.
goderbauer commentedDec 17, 2024
Maybe we need to introduce this as a new method or guard it behind a parameter to not break all the existing code? |
goderbauer commentedJan 14, 2025
(triage):@hgraceb Are you interested in updating this to make it opt-in (e.g. as a new method or via a parameter). |
hgraceb commentedJan 15, 2025
@goderbauer Sorry, I haven't had time to follow up on this issue recently because I've been job hunting. I might try to make some updates this week or next week. |
hgraceb commentedJan 18, 2025
@victorsanni@goderbauer Hi, I tried to keep all the original code logic and only reuse the gesture, but the Google tests are still failing. I might need some more specific error examples to make further changes. Can someone help provide a portion of the failing test code? |
victorsanni commentedJan 21, 2025
Most of the test failures are image diffs reflecting the previous behavior, as@Piinksmentioned. Can we make the behavior opt in as@goderbauerdescribed? |

Should this test also check for the correct behavior whencontinuous = false?

@victorsanni I believe that in this case, there is no such thing as the correct behavior whencontinuous = false. The fact that all tests that did not passcontinuous are currently passing is the correct behavior.
