Got it to work after manually solving the signalled issues in the de/mintware/barcode_scan/ActivityHelper.kt, de/mintware/barcode_scan/ChannelHandler.kt, and de/mintware/barcode_scan/RequestCameraPermissionHandler.kt files. Fixing means removing the ? operator.

Can you elaborate on how you fixed it?

The causing errors are really here for you:

e: C:\Users\Harish\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\barcode_scan2-4.2.0\android\src\main\kotlin\de\mintware\barcode_scan\ActivityHelper.kt: (81, 58): Type mismatch: inferred type is Array<CapturedType(out String)>? but Array<(out) String!> was expected
e: C:\Users\Harish\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\barcode_scan2-4.2.0\android\src\main\kotlin\de\mintware\barcode_scan\ActivityHelper.kt: (81, 71): Type mismatch: inferred type is IntArray? but IntArray was expected
e: C:\Users\Harish\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\barcode_scan2-4.2.0\android\src\main\kotlin\de\mintware\barcode_scan\ChannelHandler.kt: (64, 39): Type mismatch: inferred type is BinaryMessenger? but BinaryMessenger was expected

The error tells you what was provided and what is expected. So you remove the trailing ? operator on these and provide what it expects. Then the other errors will go away because they complain about function signatures.

The long term fix will probably come from the package maintainer. This is just a fix to get your project building.
