Step 3: Describe the problem:

Using Firebase UI for Phone Auth only, how can we disable back press?

Steps to reproduce:

1. Create a sample project
2. Integrate Firebase UI SDK Android
3. Use Phone auth provider
4. Press back

Observed Results:

No way of controlling the back press with Phone Auth Activity

Expected Results:

Should allow to add OnBackPressedCallback to allow consumer to control the back press behavior.

Relevant Code:

Something like this

AuthUI.IdpConfig.PhoneBuilder().addBackPressCallback(backPressedCallback)

private val backPressedCallback = object : OnBackPressedCallback(true) {

      override fun handleOnBackPressed() {

         

      }

  }
