Flutter apps hangs up in simulator after launching a url (e.g. URL Launcher)

I am developing a Flutter app and using the url_launcher package to open URLs. The app works fine on Android and older versions of iOS, but when I test it on iOS 18 using the simulator, the app hangs after launching the URL.

Here’s the code I’m using to launch the URL:

Future<void> _launchURL(Uri url) async {
  if (await canLaunchUrl(url)) {
    await launchUrl(url);
  } else {
    throw 'Could not launch $url';
  }
}

The URL launches correctly, but immediately afterward, the app becomes unresponsive, and I have to stop the simulator to continue. This issue only occurs on iOS 18; it works fine on older versions.

Steps to Reproduce:

1.  Install the url_launcher package in the Flutter app.
2.  Use the code above to launch a URL.
3.  Run the app on an iOS 18 simulator.
4.  Attempt to launch a URL.

Expected Behavior: The URL should open, and the app should remain responsive.

Actual Behavior: The URL launches, but the app hangs afterward and becomes unresponsive.

Environment:

•   Flutter: 3.24.3 (Stable branch)
•   iOS Simulator: iOS 18
•   url_launcher: ^6.3.0

Has anyone else encountered this issue? Any suggestions for resolving it would be greatly appreciated!

PS: The app also hangs when I use the sign with Google functionality (also launching an in App browser) and Stripe checkout with PayPal functionality.

import 'package:flutter_custom_tabs/flutter_custom_tabs.dart';

Future<void> _launchURL(String url) async {
  try {
    await launch(
      url,
      option: CustomTabsOption(
        toolbarColor: Theme.of(context).primaryColor,
        enableDefaultShare: true,
        enableUrlBarHiding: true,
        showPageTitle: true,
        animation: CustomTabsAnimation.slideIn(),
      ),
    );
  } catch (e) {
    // Handle error
  }
}

Try this for google and paypal checkout

Update the url_launcher package,

Future<void> _launchURL(Uri url) async {
  if (await canLaunchUrl(url)) {
    await launchUrl(
      url,
      mode: LaunchMode.externalApplication,
    );
  } else {
    throw 'Could not launch $url';
  }
}

Try this,
