60 Deploy a Flet App to GitHub Pages with GitHub Actions (Upgrade to Flet 1.0 Beta) PYTH 12.2

In this tutorial, we take a locally running Flet application and make it compatible with GitHub Pages by upgrading from Flet 0.70 to Flet 0.80 (Flet 1.0 beta) and configuring a proper GitHub Actions deployment workflow.
You’ll see why older Flet versions will not run on GitHub Pages, how to pin exact dependencies, and how to separate local development tools from production installs using optional and dev dependencies. We then build a complete GitHub Actions workflow that installs Python with UV, sets up dependencies, installs Flutter in the CI environment, builds the Flet web app, and deploys it to GitHub Pages automatically on every push.
This video focuses on the practical engineering details required to move from “works on my machine” to a reproducible, cloud-based deployment—without needing Flutter installed locally.

By the end of this video, you will have:
Upgraded a Flet project from 0.70 to 0.80 / 1.0 beta
Cleaned up dependencies for GitHub Pages compatibility
Set up a GitHub Actions workflow for automated builds and deployment
Successfully built and deployed a Flet web app to GitHub Pages

In the next video, we’ll create the GitHub repository, enable GitHub Pages, finalize the requirements file, and push the project live.
