I'm using gitlive's firebase multiplatform library. I'm trying to come up with an Instagram-like feature where users can upload many photos/videos into one post. There's some time between upload being finished and it displaying in firestore so I want to create a way to get upload updates. I see that firebase storage has something like this but it's for one single file, where I might want to upload multiple files. Does anyone know if something like this exists or any tips on implementing it?
