app terminate on disconnect for WEB_BROWSER mode

[minh-wp]

Hi All,

I'm using flet with view = WEB_BROWSER, I can't find an example to shutdown the background flet, when user close all browser session.
I can get the event for when user disconnect, but doesn't seem to have a method to terminate the app.
I'm using sys.exit() to end it, but it doesn't seem a proper way to do it.

Any help would be much appreciated.
Thanks!!!
