I am using dagger hilt 2.46 version I already tried following stackoverflow answer Given component holder class packagename.MainActivity does not implement interface dagger.hilt.internal.GeneratedComponent and other all answers it did not help I already add AndroidEntryPoint to MainActivity as well and all necessary hilt dependency as well I want to know where exactly I am making mistake
I fixed my problem by updating jetpack compose navigation version from 1.0.0 to 1.1.0-alpha01
implementation("androidx.hilt:hilt-navigation-compose:1.1.0-alpha01")
in app.gradle file
