Could not find option 'appicon_devices' in the list of available options

[karltaylor]

When I run the following command from the example

android_appicon(
    appicon_image_file: "../appIconAssets/savvy/appIcon/app-icon.png",
    appicon_devices: [:phone, :tablet], # - does not exist on android
    appicon_path: '../../android/app/src/main/res/mipmap'
  )

Could not find option 'appicon_devices' in the list of available options:
appicon_image_file, appicon_icon_types, appicon_path, appicon_filename, appicon_custom_sizes

This is because inside the android app icon actions appicon_devices is not specified as an option.

I am not sure if this is a example error or a android action error.
