googleads-mobile-flutter: NullPointerException for `intValue()`

Plugin Version

2.1.0

Steps to Reproduce

It cannot be reproduced very easily and just occurs for some users of my app. Hoping that the error message itself could lead to a solution. Some implicit cast into int must be incorrect for an argument.

Expected results: No crashes

Actual results: The app crashes regularly for many users with

java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference

Logs

Fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError :  PlatformException(error, Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference, null, java.lang.NullPointerException: Attempt to invoke virtual method 'int java.lang.Integer.intValue()' on a null object reference

Closing this issue as the fix has been addressed in https://github.com/googleads/googleads-mobile-flutter/pull/967. In the short term you can use

google_mobile_ads:
  git:
    url: https://github.com/googleads/googleads-mobile-flutter
    path: packages/google_mobile_ads

to see the recent changes. This will also be included in the next release (coming this month).

Alternatively, you could modify the create() method to handle the case where the Integer object is null:

public static void create(@Nullable Integer intValue) {
  if (intValue == null) {
    // handle the case where intValue is null
  } else {
    // use intValue here
  }
}
