Saving values with tinydb and retrieving values with datepicker

I have trouble saving input by date in one screen and then retrieving the input with the datepicker in another screen with tinydb.

Screen 1. Call tinydb to store value under tag datelist (text), value to store call clock instant clock.now with pattern dd/MM/yyyy.

Screen 2: After date set I want to show all the data that is saved on that date in a notifier with additional information.

How can I show the information on screen 2?
