I just noticed android studio got a new feature that allows us to click a button and find the consumers for a particular @Provides functions, my question is, is there any way to to kind of go through all the @Module classes and find the ones that are not used anywhere in the project in 1 iteration using a script or a tool?

Full code:

@Module
@InstallIn(ApplicationComponent::class)
object RemoteDataSourceModule {

    @Singleton
    @Provides
    fun provideNetworkApi(): NetworkApi = NetworkApi.getInstance()

    @Singleton
    @Provides
    fun provideFcmApi(): FcmApi = FcmApi.getInstance()

}

Pictures of it in Android Studio

My version of Android Studio is 4.1

enter image description here

In the picture I attached of my RemoteDataSourceModule in Android Studio you can see the left sidebar. [The one between line numbers and the code itself]

On that sidebar, you can that icon. [Not sure what it looks like] This is the icon for dependencies.

enter image description here

If you hover over that icon you will where is the particular dependency is provided. [See example in my picture]

This way you can track all the places where said dependency is injected. Once no places are detected, that icon will disappear.

Edit: I just found a link to this part of Android Studio release notes: Refer here for more information: https://developer.android.com/studio/releases#dagger-navigation

    you gave me something useful with "no icon displayed if no uses" part (gave you an upvote for that one and the nice clear suggestion), but apart from that what I am actually looking for here is to get ALL the unused provides function names at once, manually going through each of them is very painful, there are 100s of provides functions in my project – Bhargav Nov 06 '20 at 04:07
