How to add a File Picker plugin in Flutter?

Question

I am creating a Flutter project in which, I have a piece of data (JSON) that I want to Import from and Export to a location the user wants to. In order to achieve this, I require a File Picker plugin in Flutter. Now, I searched the Dart Packages repository for "file picker" but didn't find one.

Is there a way to get a File Picker that looks like this:

or even this...

The first screenshot is preferable for me as it allows file selection from different sources (like Drive).

Also, since I want to Export the data, I might want a Folder Picker too. ;)
But, if there is any other alternative to Folder Picker. I'd be happy to know...

I've created a file_picker plugin some time ago in order to make it possible to pick (both on iOS and Android) absolute paths and then loaded it with Flutter.
