It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). 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. 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. |

A nullable boolean should only be used when there are three conceptually different states. The code in this PR only actually recognizes two.

That's a Dart unit test, which does not run the code you changed; native unit tests are here, as described in our contributor docs. |

Oh, my God. I forgot. Thanks for the reminder. I’ve added the test. If you have time, you can continue review |

Is .failedToLoad the correct result here? Or we should add a new InAppLoadResult.dismissed result?
If this is the correct result, should we update this comment to indicate this case can happen if the user dismisses the Safari view before the initial load completes?

At first, I did consider adding a new InAppLoadResult to describe the close action, but it seems it could lead to confusion among developers. This is because, currently, after a successful load, clicking the close button does not trigger any callback.
Additionally, when the user clicks close before the loading is complete, triggering the failedToLoad callback seems reasonable in a broader sense, as the interruption of the loading process can be considered a loading failure.

Do you think it’s possible to modify the comment like this:
// The URL did not load successfully (or close the SFSafariViewController earlier)

When SFSafariViewController is loading a webpage, if the close button is clicked during the loading process, it can prevent the callback from being triggered correctly.
