WidgetsBindingObserver is not working on my flutter web project. Is there something similar to detect when the user closes the browser like closing on the native device app with widgetbinding?
I want to rebuild the whole website after every time the browser was rebuilt regardless if the website was left open before.
Hook into the browser's visibility change API.
import 'dart:html';
// inside your State class
@override
void initState() {
super.initState();
document.addEventListener("visibilitychange", onVisibilityChange);
}
@override
void dispose() {
document.removeEventListener("visibilitychange", onVisibilityChange);
super.dispose();
}
void onVisibilityChange(Event e) {
// do something
}
