// depending on and injecting:
// - @react-native-community/cli-platform-android
// - @react-native-community/cli-platform-ios
// - @react-native/community-cli-plugin (via the @react-native/core-cli-utils package)
// - codegen command should be inhoused into @react-native-community/cli
//
// This is a temporary workaround.
