This needs a test that verifies that the correct label is used when the placeholder or regular image is shown.

I prefer this usage as well, I haven't included them because it was used this way in the Image class. I will add it.

@salihgueler in #33370 I propose that we remove the Based on a quick code search, I didn't see any usages of this property either. Do you have any objections to this removal? If so, please comment in #33370 Thanks! |
This updates FadeInImage to use the new Image.frameBuilder API (added in #33369), to greatly simplify the implementation of FadeInImage. This also removes the FadeInImage.placeholderSemanticLabel property. This property was added in #28799 for the sake of completeness (the bug it fixed was the lack of any semantic label support in FadeInImage), but a placeholder is a transient visual artifact, not something that affects the underlying semantic meaning of the image.

This PR is adding semantics label and Semantics to FadeInImage. It has two semantics label one for placeholder and another for the real image. It brings the semantics label according to the image shown on screen. I got the idea to add different semantics for placeholder and image from @jonahwilliams on the related issue.
This fixes #26040
