wow that brings back memories. back then android was truly hideous compared to iOS, unless aided by 3rd party launchers.
Flutter doesn't even support pasting images at all (so things like messaging apps can't support pasting images). I get an impression that Google/Android want copy-paste to disappear. My favourite conspiracy theory on this is that it's so people will have to use the "share" sheet, which shares links with tracking/analytics (rather than pasting a raw image which cannot be tracked).
