"""
A material design circular progress indicator, which spins to indicate that the application is busy.
A control that shows progress along a circle.
Example:
```
from time import sleep
import flet as ft
def main(page: ft.Page):
pr = ft.ProgressRing(width=16, height=16, stroke_width = 2)
page.add(
ft.Text("Circular progress indicator", style="headlineSmall"),
ft.Row([pr, ft.Text("Wait for the completion...")]),
ft.Text("Indeterminate circular progress", style="headlineSmall"),
ft.Column(
[ft.ProgressRing(), ft.Text("I'm going to run for ages...")],
horizontal_alignment=ft.CrossAxisAlignment.CENTER,
),
)
for i in range(0, 101):
pr.value = i * 0.01
sleep(0.1)
page.update()
ft.app(target=main)
```
