**flutter_blue_plus** This version of %1 is not compatible with the version of >Windows you're running. What should I do?

So this project of mine had flutter_blue plugin in it. And I just switched to flutter_blue_plus. And now I can't run it on my system. And this is the error it shows. And when I checked, it feels like no one else is facing this issue. There's no mention on the flutter_blue_plus package issue list either. And i found some of the similar kind of problems on stackOverflow from years ago. And it seems like they're just android problems. And I'm not an android developer. Another known flutter developer faced the same issue with the original flutter_blue package on M1 pro. And on his device, flutter_blue_plus runs properly. I'm using Windows 11 for my development.

FAILURE: Build failed with an exception.

  • What went wrong: Execution failed for task ':flutter_blue_plus:generateDebugProto'.

I've tried the basic steps, like cleaning and rebuilding project. And here is the device speceficaiton im using. flutter doctor -v.

Solution

  • If someone is facing this problem. Or anything that looks familiar to it. You can try checking your gradle.properties file inside your projects android folder. And if there's any line that looks like this

    protoc_platform=osx-x86_64

    Try removing it. To my little bit of understanding it's just saying the gradle system to look for the macOs operating system while creating the protoc buffer. And it's not finding it bcz the platform is windows. At least in my case, it was. It can be vice versa.
