Questions to Ask Before Submission
- Does you app launch successfully without wrapping? yes
- Have you reviewed the prerequisites for App Wrapping? yes
- Does your issue have a solution in the Troubleshooting Guide? yes
- Have you checked the Microsoft Intune App SDK for Android repository for similar issues? yes
- 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 am looking into this
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.
