Hi @ipconfiger
I just commited a change that I confirmed working for the example app and some swift projects. Please try with the latest version of flutter by changing your pubspec to target the master branch, like so, and let me know the results.

dependencies:
  flutter_blue:
    git: git://github.com/pauldemarco/flutter_blue.git

On a new and clean Flutter/Swift project I added the dependency as

flutter_blue:
git: git://github.com/pauldemarco/flutter_blue.git

And I am getting the ''FlutterBluePlugin.h' file not found" error in xcode when building.

You can have a quick fix for this problem by recreating the ios side of the project with objective-c.

flutter create -i objc project_name

I am also getting the ''FlutterBluePlugin.h' file not found" error in XCode when building in Android Studio. The quick fix suggested by @dreampowder completes in the terminal, with instructions at the end to use 'flutter run', but that produces exactly the same missing file error.

@andrewknockin did you run the "flutter clean" command?
this error is based on the framework support came with cocoapods + swift. it is not possible to get this error from flutter_blue.framework because there is no framework generated with objective-c.

[andrewknockin]

@dreampowder yes I have just run flutter clean in the project directory. Still get the error with flutter run. It actually says 'build done' before the error.
Xcode build done. 24.1s

@dreampowder I seem to have got past that error now. I had a copy of the library as another adjacent project. That contained the only copy of FlutterBluePlugin.h I could find on my system. I have totally deleted that copy of the library and run flutter clean. Now flutter run gives an error output from CocoaPods which should be in a different thread. Thanks for your help.
Automatically assigning platform iOS with version 10.0 on target
Runner because no platform was specified. Please specify a platform for

[dreampowder]

@andrewknockin thats not an important error, but if you really want it to go away, you can remove the. # from the version line found in the podfile file found in your ios folder

I and my team have encountered this problem several times.
I can't say I understand it as I got the project to work one time but the problem had returned with no apparent change.
In the end, the solution that worked for us is to go to the library and set the headers as public and not project level.
If this action has side effects I'm not aware I would be happy to hear that.

Hope it helps.

the code insert where? thanks
