Firebase File Upload Progress Jumps From 0 To 100

I'm using the Firebase Storage to upload files. https://firebase.google.com/docs/storage/web/upload-files#monitor_upload_progress The upload works well, but the on('state_changed')

Solution 1:

The number of time the state_changed event is raised, depends on the size of the file you upload: if fires for each block of 256KB. So if the file is <256KB this is expected behavior.
