[Bug]: IllegalStateException: Reply already submitted

[joelsuite]

Description

Currently in our ios and android app we are calling the FlutterWebAuth2.authenticate method. For the majority of users on both ios and android this works with no problem. However, for a number of Samsung models we encounter the following:

IllegalStateException: Reply already submitted

Our logging package informs us that this error is being thrown when the following is called:

flutter_web_auth_2.dart in FlutterWebAuth2._cleanUpDanglingCalls at line 93 within flutter_web_auth_2

We believe this is originating from the native code backing the flutter_web_auth_2 package rather than being a problem with how we have called authenticate.

Minimal Reproduction

Steps to reproduce the behaviour:

We have been unable to reproduce this problem ourselves as it appears to occur in specific models of phone, that we do not currently use for testing.

Our call to authenticate is as follows:

     String result = await FlutterWebAuth2.authenticate(
      url: authorizeUrl.toString(),
      callbackUrlScheme: Platform.isIOS ? "churchsuite" : "https",
    ).onError((error, stackTrace) {
      // throw anything that needs throwing!
      logError(error.toString(), stackTrace: stackTrace);
      if (error is Exception) throw error;
      return '';
    });

I realise this is less than ideal, so please ask any clarifying questions if that would be helpful.

Expected Behaviour

After clicking login on this app we expect the user to proceed to our oAuth login screen and then return to our app having successfully completed our login flow.
