I didn't want to post in the main update thread because that is already drowning in comments. While FF devs are resolving issues, I am trying to debug myself wherever I can. My issue is related to apk download not being able to produce a working apk after the update, and my local run is not working either so these 2 issues are definitely related.
I have attached a picture and you can see after the update it seems all my font files and custom icon files (imported as ttf) are thrown into the root directory instead of the fonts folder.
This was easy to resolve and the build error message specifically mentioned unable to detect [specific_filename] mentioned in pubspec.yaml, but I also had to do some renaming because FF added _numbers behind the filename.
After resolving this I used bash to manually resolve pub dev dependencies using get and major versions commands etc.
After that I tried local run and export to virtual device again, and a whole batch of new errors came up, including other broken assets and links like loaders spinkit etc.
My serious question is: why wasn't all these tested and verified working before releasing the update? If assets are not migrating properly then definitely the FF team QC has failed tremendously as these are just basic file folder management, and not more serious cases like widget and component issues.
I hope this gets resolved soon because now my project is stuck in limbo. Feel free to add helpful info as im sure the above related minor debugging my help people in the right direction.
