for people that use Kotlin i advice to stop using dagger and go for this light weight plugin
--> Koin
To Know how to use Koin i made a simple tutorial for every purpose in here :
--> Koin Tutos
I guess this is now deprecated and you should use Hilt Worker Injection
@cbeyls : you can still use this. Dagger is a Java library that has been used on Android. Now they made a much simpler way to do DI using Hilt.
But personally I like Koin much more!!
@rickmune :
can u show how u used class UploadWorker ? Ty.
