IOS Build issue after upgrade plugin to latest

[bhanuka96]

I upgrade the plugin and run the CI. CI is failed on IOS. I checked manually and it's because of the latest version of this plugin.

    '_PlatformCallbacksHandler' is missing implementations for these members:

    Try to either
     - provide an implementation,
     - inherit an implementation from a superclass or mixin,
     - mark the class as abstract, or
     - provide a 'noSuchMethod' implementation.

Temp solution: downgrade plugin to 1.0.7

Thank you for reporting 🙇 I will take look tomorrow!

@bhanuka96 I tried to compile the example and a private project that uses the library. Both compiled without any issue on iOS. Also your error log doesn't mentioned the library with any word, I assume the error is hidden somewhere else on your side :(
