From [firebase/agent-skills], with corrections checked against Firebase documentation and current SDK source. Flutter Storage downloads also draw on ApparenceKit, corrected against the official download guide. Flutter messaging also draws on ApparenceKit and FlutterPro, with the existing Firebase message-type and handler corrections retained. This skill covers the supplied web, Node and Flutter material. Native-only Swift/Kotlin, Crashlytics and Xcode setup are outside this repository's stack.
