Please use next line for showing a Toast message in a Fragment:

 Toast.makeText(context, it, Toast.LENGTH_LONG).show()

You use viewLifecycleOwner as the first argument but it should be a Context.

I am trying to show a Toast message in a Fragment using MutableLiveData Event, but I cannot show the toast message, error is

None of the following functions can be called with the arguments supplied. makeText(Context!, CharSequence!, Int) defined in android.widget.Toast makeText(Context!, Int, Int) defined in android.widget.Toast

ViewModel

class AddProductViewModel (
    private val repository: ProductRepository,
    private val context: Context
): ViewModel(), Observable {

    private  val statusMessage = MutableLiveData<Event<String>>()

    val message : LiveData<Event<String>>
        get() = statusMessage

}

Fragment

class AddProductFragment: Fragment() {
    private lateinit var binding: AddProductBinding
    private lateinit var addProductViewModel: AddProductViewModel
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        binding =  DataBindingUtil.inflate(inflater, R.layout.add_product, container, false)
        val dao = SubscriberDatabase.getInstance(requireActivity().applicationContext).productDAO
        val repository = ProductRepository(dao)
        val factory = AddProductViewModelFactory(repository, requireActivity().applicationContext)
        addProductViewModel = ViewModelProvider(this, factory).get(AddProductViewModel::class.java)
        binding.addProductViewModel = addProductViewModel
        binding.lifecycleOwner = this
        val view = binding.root

        addProductViewModel.message.observe(viewLifecycleOwner, Observer {
            it.getContentIfNotHandled()?.let {
                ***Error is on this line***
                Toast.makeText(viewLifecycleOwner,it, Toast.LENGTH_LONG).show
            }
        })

        return view
    }
}

How can I correct this please thanks in advance
