Flet Timer

The Flet Timer is a timer component for the Flet framework that is based on the last example from the Flet User Controls guide. It demonstrates how to create a countdown timer using threading for real-time display updates.

Installation

To use the Flet Timer, you can install it using pip:

pip install flet-timer

Usage

Here's an example that demonstrates how to use the Flet Timer.

First, let's define a callback function that will execute at a specified interval:

def refresh():
    txt_time.value = datetime.now().strftime("%H:%M:%S")
    page.update()

Next, create the Timer object with the desired interval in seconds, a name, and the callback:

timer = Timer(name="timer", interval_s=1, callback=refresh)

Finally, add the Timer component to the page:

page.add(timer)

The complete example code would look like this:

from datetime import datetime
import flet as ft
from flet_timer.flet_timer import Timer


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

    txt_time = ft.Text(value="None")

    def refresh():
        txt_time.value = datetime.now().strftime("%H:%M:%S")
        page.update()

    timer = Timer(name="timer", interval_s=1, callback=refresh)

    page.add(
        timer,
        txt_time
    )


ft.app(main)

In this example, we create a Flet application that displays the current time using the Text component. We define a refresh() function that updates the txt_time value with the current time and triggers a page update. We instantiate a Timer with a 1-second interval and the refresh() function as the callback. The timer continuously calls the callback, updating the UI with the current time.
