missing packages/libraries

[Litsardos]

I am trying to use the serius_python in my project, so i can use my python algorithms in my flutter app on android and ios platforms. The issue is that i use functions in my algorithms that are included in the scipy library (and many more), that are not available in https://pypi.flet.dev/.
how could i use them?

scipy is on https://pypi.flet.dev now (1.18.0), along with scikit-learn 1.9.0, numpy, pandas and ~130 other prebuilt iOS/Android wheels — so listing it in your requirements is enough:

export SERIOUS_PYTHON_SITE_PACKAGES=$(pwd)/build/site-packages
export SERIOUS_PYTHON_APP=$(pwd)/build/app
dart run serious_python:main package app/src -p Android -r flet -r scipy

(Both env vars are required for native targets since 4.0.0; flet build sets them for you.) Wheel coverage varies per Python line, so if pip can't resolve a package for the default runtime, try pinning with export SERIOUS_PYTHON_VERSION=3.12 (or 3.13) before packaging.

For anything else: pure-Python packages work as-is on mobile, no index needed. Binary packages (C/Rust extensions) need a recipe in Mobile Forge — request them in Flet Discussions → Packages. The current list is at https://flet.dev/docs/reference/binary-packages-android-ios.

Closing — please open a new issue if a specific package you need still isn't there on 4.5.1+.
