Update on Flet: Python + Flutter UIs
talkpython.fm
As Python developers, we're incredibly lucky to have over half a million packages that we can use to build our applications with over at PyPI. However, when it comes to choosing a UI framework, the options get narrowed down very quickly. Intersect those choices with the ones that work on mobile, and you have a very short list. Flutter is a UI framework for building desktop and mobile applications, and is in fact the one that we used to build the Talk Python courses app, you'd find at talkpython.fm/apps. That's why I'm so excited about Flet. Flet is a Python UI framework that is distributed and executed on the Flutter framework, making it possible to build mobile apps and desktop apps with Python. We have Feodor Fitsner back on the show after he launched his project a couple years ago to give us an update on how close they are to a full featured mobile app framework in Python.

My personal experience writing a multi-platform desktop app (macOS, Windows, Linux) was rather painful. Tkinter was my first try, but deployment on macOS was a nightmare. I ended using PySide, which ticked all the boxes, but my biggest gripe is that you end with a lot of code that is not very “pythonic”. Flet looks like a nice alternative.
