Flet app hosted on Heroku

This is an example Flet app that can be deployed to Heroku as a web app.

Use this repository as a starting point for your own app.

In Heroku choose "GitHub" deployment method and select the repository.

A new deployment will automatically start on every push to the repository.

Key points to make Heroku work:

1. Procfile - nothing fancy, just running python {your_program.py} as a web process.
2. requirements.txt - the list of Python modules required by your program, including flet.
3. main.py - use TCP port binding provided by Heroku environment.

Heroku dynamically assigns your app a port and add its value to PORT environment variable. To make Flet app using that port you should add import os to your Flet program and modify flet.app() to use that port:

import os

# the rest of your program

flet.app(target=main, port=os.getenv("PORT"))
