Description

Getting the following errors when building the application, even if just the import statement is included:

Steps To Reproduce

1. Upgrade Flutter to latest version and Pub upgrade
2. Include flutter_blue_plus_windows to pubspec.yaml
3. Import flutter_blue_plus_windows to a dart file
4. Build on Windows

Expected Behavior

Should build without errors

Additional Context

Flutter_blue_plus alone works fine. The error occurs only in flutter_blue_plus_windows. I have tried using it in a new blank project as well.

[salarshad]

I have downgraded Flutter to version 3.27.1, and even specified older flutter_blue_plus_windows version upto 1.23.6.

But still getting the same build error.

I have tried "flutter clean" in the project, cleaning Pub cache, cleaning MS Visual Studio cache, also tried using the package in a new blank project. Tried in both VS Code and Android Studio. Also restarted the system.
