Create a new Flet app

Create a new directory (or directory with pyproject.toml already exists if initialized with poetry or uv) and switch into it.

To create a new "minimal" Flet app run the following command:

venv

flet create

uv

uv run flet create

poetry

poetry run flet create

The command will create the following directory structure:

├── README.md
├── pyproject.toml
├── src
│   ├── assets
│   │   └── icon.png
│   └── main.py
└── storage
    ├── data
    └── temp

note

Original pyproject.toml created by uv init or poetry init will be replaced with the one from Flet app template.

src/main.py contains Flet program. It has main() function where you would add UI elements (controls) to a page or a window. The application ends with a blocking ft.app() function which initializes Flet app and runs main().

You can find more information about flet create command here.

Now let's see Flet in action by running the app!
