Fix https://github.com/flutter/flutter/issues/160886 From the context of the issue, user wants to observe open/close events for search view with SearchController.isOpen. However, I think that is not a friendly approach/solution due to it relies on a TextEditingController, it is a ValueNotifier which we implicitly understand is dedicated to text input. During the investigation, I found that `viewOnClose` works perfectly because it is a callback from `_SearchViewRoute` (which is a PopupRoute so it has didPush and didPop callbacks that we can leverage). `onClose` was called on `didPop`, so we can solve this by creating a similar `onOpen` then call it on `didPush`. Users then can implement both callbacks for their needs. In this PR: - Propose adding SearchAnchor.viewOnOpen and `SearchAnchor.bar`.onOpen - Improve documentation of SearchController, so that users will not be confused with `SearchController.isOpen` #### Demo (after the fix) https://github.com/user-attachments/assets/7f30b831-e2d7-4a72-bc0f-35c858e3427b ## 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. - [x] All existing and new tests are passing.
