How to correctly use Android View Binding in DialogFragment?

Question

What is correct way of using Android View Binding in DialogFragment()?

Official documentation mentions only Activity and Fragment: https://developer.android.com/topic/libraries/view-binding

Answer 1

Use inflate(LayoutInflater.from(context)) instead. And use binding.root to set the builder view.

Also, as Google suggests, it's best practice to set the binding instance to null at onDestroyView() when using fragments: https://developer.android.com/topic/libraries/view-binding#fragments

Example:

class ExampleDialog : DialogFragment() {

    private var _binding: DialogExampleBinding? = null
    // This property is only valid between onCreateDialog and
    // onDestroyView.
    private val binding get() = _binding!!

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        _binding = DialogExampleBinding.inflate(LayoutInflater.from(context))
        return AlertDialog.Builder(requireActivity())
            .setView(binding.root)
            .create()
    }
    
    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    } 
}
