email link auth emailLink parameter question

[matthewchung74]

Following this tutorial Firebase Email Link Authentication example guide at FlutterFire

https://firebase.flutter.dev/docs/auth/usage/#email-link-authentication

I am not sure what is the right way to read the emailLink parameter. I'm doing this, right in my main.dart import 'dart:html' as html; final String launch_url = html.window.location.href; but that feels hacky and I'm assuming will not work on mobile. suggestions?
