firebase_storage_watchos 0.0.1-beta.1

watchOS implementation of firebase_storage, bridging the Firebase Apple SDK (FirebaseStorage) over dart:ffi for uploads, downloads, and metadata.

firebase_storage_watchos

The watchOS implementation of firebase_storage.

Bridges the Firebase Apple SDK (FirebaseStorage) to Flutter on watchOS over dart:ffi. Method-channel plugins are not supported on watchOS, so this package exports C symbols from watchos/Classes/firebase_storage_watchos_ffi.m that wrap FIRStorage/FIRStorageReference; watchos/Package.swift declares a SwiftPM dependency on firebase-ios-sdk's FirebaseStorage product, and Dart resolves the symbols via DynamicLibrary.process(). One-shot operations use an async begin/poll bridge; uploads and downloads run as native SDK tasks whose progress snapshots the Dart side polls.

Experimental. Firebase support on watchOS is new. This package builds, links the Firebase Apple SDK, and passes its host tests and an on-simulator smoke test, but has not yet been proven on physical watch hardware; it is published as a pre-release.

Requires firebase_core_watchos (the initialization + app registry foundation) and a flutter-watchos CLI with external-SwiftPM-dependency linking.

Implemented surface

• References: ref, child/parent/root plumbing, delete, getDownloadURL, getMetadata, updateMetadata, list, listAll.
• Data: getData, putData, putString, putFile, writeToFile.
• Tasks: snapshotEvents, snapshot, onComplete, pause, resume, cancel, with upload/download progress.
• Configuration: useStorageEmulator, setMaxOperationRetryTime, setMaxUploadRetryTime, setMaxDownloadRetryTime.

putBlob is web-only and reports unsupported.

Usage

This is a federated plugin implementation. Apps that already depend on firebase_storage and target watchOS add this package (and the firebase_core_watchos foundation) alongside it:

dependencies:
  firebase_core: ^4.0.0
  firebase_core_watchos: ^0.0.1-beta.1
  firebase_storage: ^13.0.0
  firebase_storage_watchos: ^0.0.1-beta.1

Then use firebase_storage's API exactly as on iOS — the watchOS implementation registers automatically via Flutter's federated plugin runner.
