In this hands-on Flet tutorial, we learn how to use use_state to make a Python UI truly interactive. We start with a dropdown menu that already exists but does not yet change anything on screen, then incrementally add state so the UI reacts to user input.

You will work step by step through:

Reviewing a dropdown that selects objects (not strings)

Storing application state with ft.use_state

Managing selected objects using a dictionary of character instances

Updating state inside a dropdown selection handler

Rendering dynamic UI elements based on state changes

Displaying images and character attributes (skill, luck, stamina)

Structuring layouts with Column and Row for clear visual hierarchy

This tutorial emphasizes practical Python concepts, including object-oriented design, keyword-only parameters, and clean state updates, all within a simple but engaging Flet application.

By the end, selecting a character from the dropdown updates the image and stats on screen in real time. In the next video, we’ll take a deeper dive into ft.use_state and show how to use component state to fully control your Flet UI behavior.
