Gildásio Filho 492b6f7ddf Add findChildIndexCallback examples (#133469) ... The documentation for using `findChildIndexCallback` recommends using `indexOf`, but that causes [this line](05259ca938/packages/flutter/lib/src/rendering/sliver_multi_box_adaptor.dart (L259)) to throw in debug mode, and when using `SliverList`, it breaks the render. This PR changes the usage to check if the index is not negative before using it, and changes to return `null` instead if the child wasn't able to be found. There's the related issue #107123, but this doesn't actually fix it. ----- This PR has been updated to add the snippets that were used in the `findChildIndexCallback` comment as examples with proper tests, as well as updating the comment to reference the new examples.		2023-10-18 00:26:17 +00:00
