Flutter: How to check local file list and extract files into app?

Question

As we know, our mobile phone has a function that we can check files from a file list. Just like the following picture. It seems that this function's name is filemanager. I wondered that is it possible in Flutter to achieve a similar function, which can check my own mobile phone's files and extract one of the files into my app? What packages or ways do I need?

Thanks for your help. This question may be quite puerile, but it is my first Flutter app.enter image description here

Solution

Yes! It's very much possible to create a file manager with flutter.

Here's a repo to a flutter file manager Github

Basically the most important package is included in dart(dart:io), any other package will vary on your use case.
