Build fails on Android (possible on iOS too)

[ripetrescu]

Trying to build the flutter project for Android using the nativeapi: ^0.1.0 fails with:

Execution failed for task ':cnativeapi:buildCMakeDebug[arm64-v8a]'.

  C++ build system [build] failed while executing:

        cnativeapi
    from /home/<user>/.pub-cache/hosted/pub.dev/cnativeapi-0.1.0/android

It should simply ignore the missing implementation for mobile, this could be also be happening on iOS build.

Thanks!
