Create the CI test script such as .travis.yml or .cirrus.yml in your
repository root.
    
      See fastlane CI documentation for CI specific setup.
      Shard your script to run on both Linux and macOS platforms.
      During the setup phase of the CI task, do the following:
        
          Ensure Bundler is available using gem install bundler.
          Run bundle install in [project]/android or [project]/ios.
          Make sure the Flutter SDK is available and set in PATH.
          For Android, ensure the Android SDK is available and the ANDROID_SDK_ROOT
path is set.
          For iOS, you may have to specify a dependency on Xcode (for example
osx_image: xcode9.2).
        
      
      In the script phase of the CI task:
        
          Run flutter build appbundle or
flutter build ios --release --no-codesign,
depending on the platform.
          
cd android or cd ios

          bundle exec fastlane [name of the lane]
