在Go中等效于Firebase存储的`getDownloadUrl`

How can I upload to firebase cloud storage and retrieve the download url like this api function:

https://pub.dev/documentation/firebase_storage/1.0.0/firebase_storage/StorageReference/getDownloadURL.html

https://firebase.google.com/docs/reference/android/com/google/firebase/storage/StorageReference.html#getDownloadUrl()

but in Go?

I can't seem to find anything relevant in the storage library https://godoc.org/cloud.google.com/go/storage

or the firebase storage library https://godoc.org/firebase.google.com/go/storage
