"""
A material design linear progress indicator, also known as a progress bar.
A control that shows progress along a line.
Example:
```
from time import sleep
import flet as ft
def main(page: ft.Page):
pb = ft.ProgressBar(width=400)
page.add(
ft.Text("Linear progress indicator", style="headlineSmall"),
ft.Column([ ft.Text("Doing something..."), pb]),
ft.Text("Indeterminate progress bar", style="headlineSmall"),
ft.ProgressBar(width=400, color="amber", bgcolor="#eeeeee"),
)
for i in range(0, 101):
pb.value = i * 0.01
sleep(0.1)
page.update()
ft.app(target=main)
```
