We have fiddled with this a bunch, and there is definitively no way to reliably include this, so I am removing it.
Since CI does not cover all possible values, we can't consistently look up images for local testing. We thought removing it from the look up would work fine, and it did for most tests, but there were still some that could not find an image without it.
A brief history on the abi key
- added in https://github.com/flutter/flutter/pull/143621
- disabled in https://github.com/flutter/flutter/pull/148023
- added back in https://github.com/flutter/flutter/pull/148072
- we thought there was only an issue with alphabetizing keys
- removed from local image look up in https://github.com/flutter/flutter/pull/149696
I updated the docs page to also discuss what makes a good key and what does not based on what we learned here.
