I am using Anvil and I have a class with no arg constructor and which doesnt extend any interface and I'm tempted to add it with @ContributesBinding(...), but this requires that target class extends some interface.

Is it wrong to wish this? It just looks simpler than writing a boring provide with MyClass() in the Module.

You don't need to create a provide method. Just add an @Inject annotation to your empty constructor.

class MyClass @Inject constructor() {}

awesome. I faintly remembered something like this could work, but wasn't sure. It has been quite some time since I last used Dagger 🙂

That sample doesn’t work. You can only use @ContributesTo for Dagger modules and component interfaces, but not classes with an @Inject constructor.

[ralf]

If you don’t have any super types, then you don’t need Anvil at all. You can simply inject the type with the @Inject constructor. Nothing else is needed.

Thanks @ralf I removed the wrong annotation, that's what I get for writing sudo code on my phone after just waking up 😅
