How Do I Code Checkboxes and How Do I Save It?

I'm planning on making a check-list with checkboxes but I don't know how to code it so that you can uncheck and check them I also don't know how to save it. Like when you go to another screen and go back to it you can still see it checked or unchecked. I barely know anything about coding yet so help is greatly appreciated!

What the app would look like:

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps

How to do a lot of basic things with App Inventor are described here: How do you...? .

If you expect the number of check boxes to grow, you will need to switch to a list based approach, where you keep lists of the text values of the checked checkboxes and the non-checked checkboxes.

A single ListView or List Picker can act as a bunch of checkboxes.
