Flet is a framework that allows building web, desktop and mobile applications
in Python without prior experience in frontend development.

### ⚡️ From idea to app in minutes

An internal tool or a dashboard for your team, weekend project, data entry form, kiosk app,
or high-fidelity prototype - Flet is an ideal framework to quickly hack great-looking
interactive apps to serve a group of users.

### 📐 Simple architecture

No more complex architecture with JavaScript frontend, REST API backend, database, cache, etc.
With Flet you just write a monolith stateful app in Python only and get multi-user,
real-time Single-Page Application (SPA).

### 🔋 Batteries included

To start developing with Flet, you just need your favorite IDE or text editor.
No SDKs, no thousands of dependencies, no complex tooling - Flet has a built-in web server
with assets hosting and desktop clients.

Flet UI is built with [Flutter](https://flutter.dev/), so your app looks professional and could be delivered to any platform.
Flet simplifies the Flutter model by combining smaller "widgets" to ready-to-use "controls"
with an imperative programming model. 

### 📱 Deliver to any device or platform

Package your Flet app as a standalone desktop app (for Windows, macOS, and Linux), mobile
app (for iOS and Android), dynamic/static Web app or as a Progressive Web App ([PWA](https://web.dev/what-are-pwas/)).

## Flet app example

Below is a simple "Counter" app, with a text field and two buttons to increment and decrement the counter value:

```python title="counter.py"
import flet as ft

def main(page: ft.Page):
    page.title = "Flet counter example"
    page.vertical_alignment = ft.MainAxisAlignment.CENTER

    input = ft.TextField(value="0", text_align=ft.TextAlign.RIGHT, width=100)

    def minus_click(e):
        input.value = str(int(input.value) - 1)
        page.update()

    def plus_click(e):
        input.value = str(int(input.value) + 1)
        page.update()

    page.add(
        ft.Row(
            alignment=ft.alignment.center,
            controls=[
                ft.IconButton(ft.Icons.REMOVE, on_click=minus_click),
                input,
                ft.IconButton(ft.Icons.ADD, on_click=plus_click),
            ],
        )
    )

ft.run(main)
```

To run the app, install `flet`:

```bash
pip install 'flet[all]'
```

then launch the app:

```bash
flet run counter.py
```

This will open the app in a native OS window - what a nice alternative to Electron! 🙂

To run the same app as a web app, update the last line in your script to:

```python
ft.run(main, view=flet.AppView.WEB_BROWSER)
```

Alternatively, you can use the `--web` flag when running the `flet run` command:

```bash
flet run --web counter.py
```
