Wrapping related to PackageManager does not work properly.

[JosephNK]

Questions to Ask Before Submission

1. Does you app launch successfully without wrapping? yes
2. Have you reviewed the prerequisites for App Wrapping? yes
3. Does your issue have a solution in the Troubleshooting Guide? yes
4. Have you checked the Microsoft Intune App SDK for Android repository for similar issues? yes
5. Are you using the latest version of the App Wrapper? yes

Describe the bug: We are using flutter_inappwebview library. What we've seen here is that before wrapping, in debug and release, function values usually return a non-null value, which works fine. However, after wrapping it returns Null, which doesn't work properly.

To Reproduce Steps to reproduce the behavior:

• Call the function
• Return value Null

Expected behavior: The function must return a non-Null value.

I added an library link, but the issue is not a library issue. After creating a new Android project and writing only the code above, the return value is equally incorrect when wrapping.
