Fixes future warning for `await`ing `Future` returns in `async` bodies inside `try` blocks by FMorschel · Pull Request #182301 · flutter/flutter

FMorschel · 2026-02-12T17:04:31Z

This is merely an analyzer change to avoid the bug explained at:

Linter rule to prevent returning futures from the try block dart-lang/sdk#62555.

This will allow the development of a warning about these situations so we can avoid this bug in the future.

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

test-exempt: unblocks future analyzer update

Code Review

This pull request adds await keywords to return statements within try blocks in async functions. Specifically, it modifies instantiateImageCodecWithSize in painting.dart and fetchImage in canvaskit/image.dart. These changes ensure that if a returned Future completes with an error, it is correctly handled by the surrounding try-catch or try-finally blocks, preventing potential resource leaks or unhandled exceptions.

It has been two weeks since this was opened. When will this be assigned to a reviewer, @stuartmorgan-g? Do I need to do anything else?

stuartmorgan-g · 2026-02-24T14:21:10Z

When will this be assigned to a reviewer, @stuartmorgan-g?

I don't run any of the flutter/flutter PR triages, so I'm not sure why that question is directed to me.

FMorschel · 2026-02-24T14:24:40Z

I'm not sure why that question is directed to me.

Sorry! I wasn't aware. I only asked you because you gave this PR the test exemption.

In that case, I'll wait a bit longer, and if nobody answers, I'll ask over on Discord.
