Is there a way for user to create file?

I wanted to create a page in my app where users could create file and store them, being able to view them on the same page after they are saved (like a database).
How would I go about doing this? I see there's a Write and Read function for the File1 component, but there's nothing to allow the user to add a file. What would I do for this?

SaveFile creates a new text tile
