I am using ViewModel inside BottomSheetDialogFragmet() so I have to mark my BottomSheet with @AndroidEntryPoint.
@AndroidEntryPoint
class SearchAddressDialog : BottomSheetDialogFragment() {
private val viewModel: MyAddressesViewModel by viewModels()
......
}
But when I tried to build my project it is giving me this error:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing
org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
> java.lang.reflect.InvocationTargetException (no error message)
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option
to get more log output. Run with --scan to get full insights.
And here is my output for run with --stacktrace

If I delete the @AndroidEntryPoint above my BottomSheetFragmen() it is building and installing the app. But when I try to open the bottomSheet the app is crashing as I injected my repositories to the ViewModel:

@AndroidEntryPoint is working without errors on other ordinary Fragments.
UPDATE:
Here is my view model:
@HiltViewModel
class MyAddressesViewModel @Inject constructor(
private val repository: AddressRepository,
private val geocoderRepository: GeocoderRepository
) : ViewModel() {}
UPDATE 2: Right now I am annotating BottomSheetDialogFragment() and it is giving me errors while building.
And If I change this
@AndroidEntryPoint
class SearchAddressDialog : BottomSheetDialogFragment(){
to this
@AndroidEntryPoint
class SearchAddressDialog : Fragment() {
it is working perfectly fine.
Can I actually annotate BottomSheetDialogFragment() with @AndroidEntryPoint?
UPDATE 3:
After long research, I couldn't solve the @AndroidEntryPoint problem. And I have come up with this: I just pass my ViewModel to my BottomSheetDialogFragment on its constructor:
class SearchAddressDialog(
private val viewModel: MyAddressesViewModel
) : BottomSheetDialogFragment() {
........
}
And I opened my dialog like this:
val dialog = SearchAddressDialog(viewModel)
dialog.show(childFragmentManager, SearchAddressDialog.TAG)
I have used the ViewModel of the current fragment.
