[REQUIRED] Step 2: Describe your environment

• Android Studio version: Arctic Fox 2020.3.1 patch 2
• Firebase Component: Dynamic Links KTX
• Component version: 20.1.1

[REQUIRED] Step 3: Describe the problem

When running the sample code for Dynamic Links in Kotlin, the result of the addOnSuccessListener is not correctly marked as a nullable type, despite it being possible to return as null.

Steps to reproduce:

• Follow the sample code setup in Kotlin
• Call the sample code with an intent that doesn't return pendingDynamicLinkData
• Observe that null is returned for the non-nullable type param of the success callback

Relevant Code:

Firebase.dynamicLinks
        .getDynamicLink(intent)
        .addOnSuccessListener(this) { pendingDynamicLinkData ->

            // **BUG** Android Studio reports this check to always be true
            //  as the typing of pendingDynamicLinkData is not nullable
            if (pendingDynamicLinkData != null) {
               // some code here ...
            }
        }
        .addOnFailureListener(this) { e -> Log.w(TAG, "getDynamicLink:onFailure", e) }
