Flutter version 3.7 is not reading asset variants #119462
Description
Steps to Reproduce
I am developing an app and am testing mostly in the mobile simulators. I have different config files for the different platforms that I have specified in the assets section of pubspec.yaml and am relying on variants to modify the config files per environment. So my assets section looks like this:
assets:
# ... other assets
- config/android.json
- config/ios.jsonwhile my directory structure looks something like
config/
local/ // <- directory per env
android.json
ios.json
dev/
android.json
ios.json
prod/
android.json
ios.json
// etc
This has been working for me while using flutter up to version 3.3.10. However, after upgrading to 3.7, starting the app in at least the iOS simulator leads to the error No file or variants found for asset: config/android.json. After flutter downgrade 3.3.10, my app works as before.
Expected results:
App runs as before, asset variants are found and accessible
Actual results:
Error finding non-variant asset
