class MyViewModel(private val mRepository: MyRepository) : ViewModel() ...
Next, in our ViewModelFactory create ViewModel method (overriden) looks like this:
override fun create(modelClass: Class): T {
return try {
//MISSED RETURN VALUE HERE''
} catch (e: InstantiationException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: IllegalAccessException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)
} catch (e: NoSuchMethodException) {
throw RuntimeException("Cannot create an instance of $modelClass", e)

}
}
