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.

Reasons:
Due to API changes, flutter_blue_plus_windows 1.25.2 does not support flutter_blue_plus 1.35.2(because the flutter_blue_plus update the flutter_blue_plus_platform_interface 2.0.0 )But because flutter_blue_plus_windows pubspec.yaml's dependencies default to flutter_blue_plus:">=1.32.4 <=1.40.0", After flutter_blue_plus has been updated to 1.35.0, flutter_blue_plus_windows will have these problems
The solution:
Method 1: clone project into the package directory to be imported, manually import flutter_blue_plus_windows dependency, control version 1.35.4
Method 2: Change... /.. AppData/Local/Pub/Cache/hosted/Pub. The dev/flutter_blue_plus_windows - pubspec 1.25.2 directory. Yaml, control its version less than or equal to 1.35.4
