Built-in binary Python packages for Android and iOS

Binary Python packages (as opposed to "pure" Python packages written entirely in Python) contain components written in C, Rust, or other languages that produce native code. Common examples include numpy, cryptography, and pydantic.

Flet provides an alternative package index, pypi.flet.dev, which hosts prebuilt Python binary wheels (.whl files used by pip) for iOS and Android platforms.

Need another package?

If a package is not available on pypi.flet.dev, you can request it in Flet discussions - Packages. Please do not request "pure" Python packages. Check out this guide for more details on the difference between pure and binary packages.
