Gradle obfuscation crashes the tinder-scarlet in startup

[MohammadFakhraee]

I know this might be an irrelevant issue. But as Tinder Scarlet library is not being updated and you are using this library, so you might face the issue which I couldn't solve.

With gradle version above 8, there is a weird issue with obfuscation. I am trying to run the scarlet demo app when enabling obfuscation with minifyEnabled true but it crashes with the following message:

java.lang.IllegalArgumentException: Receive method must return ParameterizedType: public abstract kotlinx.coroutines.flow.Flow com.tinder.app.echo.api.EchoService.observeBitmap()

The problem is when the demo is not minifying, the methods of scarlet service interfaces has a genericReturnType of ParameterizedTypeImpl type. But when switching minifyingEnabled on, the genericReturnType will become a type of java.lang.Class.
