If you use url_launcher on Android to open either a https link or mailto link everything works find.
However, if you open an https link that will have a button opening a mailto link, it fails.

Steps to Reproduce

Only on Android

  1. Open the website using url_launcher, for example flutter.dev
  2. Scroll down to Press section in the footer and click it (it has mailto: hyperlink)

Expected results:
I expect a mailing app to be opened

Actual results:
An error page with error: ERR_UNKNOWN_URL_SCHEME

Code sample 
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher_string.dart';

void main() {
  runApp(_MyApp());
}

class _MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: ElevatedButton(
            onPressed: () => launchUrlString('https://flutter.dev'),
            child: const Text('Open flutter.dev'),
          ),
        ),
      ),
    );
  }
}

    It's not the same case. I don't want to launch mailto directly from urlLauncher. I want to launch a https link which will open a webview in which there will be clickable mailto link.

    One way to fix this issue would be for us to switch to opening URLs in a Chrome custom tab rather than our own webview screen:

    Specifically, I reproduced this issue, and then went and opened the same web page in a Chrome custom tab in a non-Flutter app. There, the same mailto: link successfully opened a mail client, ready to compose a message to the given recipient.

    Anyone affected by this issue can flutter pub upgrade to pick up url_launcher_android 6.1.0 or later, and in supported configurations in-app mode will use Custom Tabs instead of the previous webview, which won't have this issue.

    I was not able to reproduce the issue using the provided code sample on either the stable (3.29.3) or master (3.33.0-1.0.pre.83) channels.

    The "Press" hyperlink isn't available on the Flutter website, so I used a different site to reproduce the issue.

    url_launcher - 6.3.1
