Does Flet actually run python on device or is it that a server communicates with the Flutter frontend?

Hi guys, Flutter developer here. The project looks pretty promising, I am looking to develop an app for Android and iOS since I have an existing python codebase for my logic which I would like to keep. One thing I cannot figure out: Does Flet actually run python on the device? Or is it all the python running on server and just communicating with the Flutter frontend?

Thanks for your interest! Flet runs Python on the device with the help of https://pub.dev/packages/serious_python plug-in (also developed by us for Flet).

Thanks! I am trying to set it up now with serious_python and Flutter.
Many things already work!

However, I am trying to implement Dash, but as soon as I import the library and run the app, the python logic doesn't seem to run anymore. Any ideas why this is? Also how to debug in general? Where do I see the print statements?

Thank you.
