how to trigger onUrlChange ？

I can’t monitor it when switching the h5 page in webview, how can I do it?

this is my code:

void initState() {
super.initState();
_urlChangeListener = flutterWebviewPlugin.onUrlChanged.listen((String url) {
print('123456789876543, $url');
if(mounted) {

}
});
}

Start with the initState snippet and its onUrlChanged subscription, then reproduce switching the H5 page in the webview while observing the printed URL output. The issue names no repository file or test; done means establishing whether the listener can observe this navigation and documenting the supported trigger or limitation.
