[Help]: Error with Flutter Blue Plus Plugin when Using Method Channel in iOS Native App #818

What is your problem?

I'm encountering an error with the blue_plus library when trying to use my module in a native iOS app using method channel.

When I build directly from Flutter on the iPhone, it works perfectly. However, when using it via method channel, with the Flutter project being a module, it always throws an error. It seems like it never manages to access the Bluetooth, even though I've added the necessary permissions in the info.plist.

I've looked at the README 'Common Problems' section

did you lie about this?

No, I didn't lie about it, the issue is that despite trying cleaning, reinstalling, changing devices, restarting the system, the error still persists, and it only happens via method channel. In the native Flutter application, it runs perfectly, as mentioned in the first line of my comment.

Hmm. Okay it was not clear to me.

This sounds like you have a problem in your build setup. But I'm not sure the solution.
