How to build a task manager using Python 3, Flet, SQLite

Build Listloom, a desktop task manager with lists, due dates, filters, and packaging notes with Python 3, Flet, SQLite.

What you are building

Listloom is a task manager you assemble in twelve short stages. The teaching stack is Flet (Python 3, Flet, SQLite). By the end you should understand the shell, the data you persist, and the everyday workflows people expect from this kind of app.

Flet brings Flutter-style controls to Python. A task manager is a crisp CRUD UI with checkboxes and filters.

ListView plus form fields teach reactive page updates. Keep SQLite access in helper functions beside the page.

Work in order. Early folders are intentionally small so you can see the window (or server) boot before features pile on. From the data-layer part onward, each snapshot should still run after you install dependencies.

How to use these lessons

Read the goal, clone the matching GitHub folder, run it, then skim the code against the notes below. If something fails, fix the run path first—most “bugs” on day one are the wrong directory or a skipped install.

Each chapter below is one checkpoint. Open a part when you are ready for that feature—not all at once.
