[firebase_storage] add support for sessionUri

[yosef-abraham]

Is your feature request related to a problem? Please describe.
When the app is closed, there's no way to resume an upload task using the sessionUri same as in the native implementations, so I have to restart the upload

Describe the solution you'd like
Adding sessionUri as a param to putFile

Additional context
The events snapshot already contain the sessionUri

Is this something you guys will be willing to accept a PR for?

Hey, any updates?

#724 is closed saying it is already implemented but it is not implemented.
Looking at the native documentation I can see that resume() and Continuing Uploads Across Process Restarts using uploadSessionUri as two different things.

https://firebase.google.com/docs/storage/android/upload-files#manage_uploads

https://firebase.google.com/docs/storage/android/upload-files#continuing_uploads_across_process_restarts

resume() only resumes a pause()ed uploads not the one after application restarts.

I've taken a look into this as part of the rework, it wont be landing in the initial rework but there's a potential for it to be implemented further down the line. Some observations:

• It's an Android only API.
• Restoring tasks is easy enough, however integrating this in Dart side is trickier.. If the app resumes from a state the Dart code is restarted and we'd need to recreate the tasks on the back of the resumed ones.
• "The events snapshot already contain the sessionUri", this is true, however they are currently unused.

Also really interested in this feature, as currently a developer needs to maintain a lot of extra logic to support the case where the app is closed while uploading.

Curious if there has been any progress on this?

No progress - right now we need it to be a feature across Android, iOS & Web for it to be considered.
