public class FirebaseDownloadExample : MonoBehaviour
{
    private FirebaseStorage storage;
    private StorageReference storageRef;

        storage = FirebaseStorage.DefaultInstance;
        storageRef = storage.GetReferenceFromUrl("YOUR_STORAGE_URL");

        // 开始下载文件
        downloadTask = storageRef.Child("path/to/file").GetFileAsync("local/path/to/save")
            .ContinueWith((Task<StorageTask> task) =>
            {
                if (task.IsFaulted || task.IsCanceled)
