Unable to load asset in master #14220
Description
Steps to Reproduce
I have an image asset that works fine in dev. However, if I flutter channel master and flutter clean it no longer loads:
I/flutter (29513): ══╡ EXCEPTION CAUGHT BY SERVICES ╞══════════════════════════════════════════════════════════════════
I/flutter (29513): The following assertion was thrown resolving an image codec:

My pubspec looks like:
flutter:
uses-material-design: true
assets:
- assets/logo.png
I have tried a release build via flutter build apk and the problem persists there. I unzipped the APK and verified that the images are in fact present and do appear to be in the correct location.

Repro
Running this on the alpha channel works as expected (a black rectangular image displays centered on screen). However, if I switch to master I get the above error.
I'm running this on a Pixel 5" using Windows 10 as my development machine.
Aside: flutter channel dev is not currently working for me - it just does nothing, leaving you on the existing channel, which was hell confusing. Using git checkout dev in the flutter repo did exactly the same thing (nothing). git branch -a shows remotes/origin/dev, so not sure what's going on :/
