I've tried everything for 2 weeks to try to get a photo to post to a collection in Firebase. I can upload photos within the app and display them, but when I go to save my post, everything but the photos post. When I try to upload directly through the Firebase manager in Flutter flow, it has an option to upload a photo are enter a URL. When I select Upload photo, it allows me to select a jpeg and displays a preview, but won't let me save. I've viewed every tutorial on Youtube and still nothing works for me.
