You can check the URL then change the state:

navigationDelegate: (NavigationRequest request) {
    if (request.url == 'http://destination.com/') {
       setState(() {
           _dstReached = true;           
       });
       // do not navigate
       return NavigationDecision.prevent;
    }

    return NavigationDecision.navigate;
}

In the build function, you can check the state and build the next widget like this:

@override
  Widget build(BuildContext context) {
    return Scaffold(
        // display Text widget if destination was reached
        // otherwise use WebView
        body: _dstReached ? Text('next step') : Column(
            children: [
              Expanded(
                child: WebView(...
