serious_python 0.8.0

A cross-platform plugin for adding embedded Python runtime to your Flutter apps.

0.8.0

• Not based on Kivy!
• Fast packaging uses pre-built Python binary packages hosted on https://pypi.flet.dev and https://pypi.org. If a binary package for specific platform/arch is not found the packaging process does not make an attempt to compile it, but just exits with a meaningful error.
• To package for iOS and Android developer should set SERIOUS_PYTHON_SITE_PACKAGES environment variable with a path to a temp directory for installed app packages. The contents of that directory is embedded into app bundle during app compilation. For macOS, Linux and Windows app packages are installed into __pypackages__ inside app package asset zip.
• Packaging command is not looking for requirements.txt or pyproject.toml anymore, but all requirements should be passed explicitly via --requirements option. The value of --requirements option is passed "as is" to pip command. For example, --requirements flet,numpy==2.1.1 install two requirements directly, or --requirements -r,requirements.txt installs deps from a file.
• MacOS packaging includes Python binaries for both arm64 and x86_64 architectures. Can limit to only one architecture with --arch option.
• New options to enable compilation and cleanup of app and packages .py files: --compile-app, --compile-packages and --cleanup.
• Packaging for web is no longer relied on a HTML document with links, but spawns its own PyPI-compatible server with links to Pyodide packages.
• Build python distributive is cached in Flutter's build directory, not temp, to avoid re-downloading on consequent re-packages.
• Web builds updated to Pyodide 0.26.2.
• Packages for iOS and Android are built with Mobile Forge.
• Python for all platforms is built with flet-dev/python-build and this CI job. Python distros for Dart and Mobile Forge uploaded to releases.
