Best practices....
Could you also describe how to use provider in the best way (consumers)

[mauricevolaski]

One thing I think can be improved is a way to display the progress of data being fetched. Say I am importing 5, 000 items and that takes 30 seconds. It would be nice to let the user have some indication of how much progress has been made and roughly when to expect the data, so the user doesn’t think the app is hung. To do this, FutureBuilder should have options for max data size or count and the current iteration, so it can display a progress indicator with actual progress.
