Flutter 使用 url_launcher 从默认浏览器运行 url

Question

I'm using url_launcher (6.1.5) and I want open the urls in default browser instead of in-app webView.

It seems that the latest version does not support it, since launch function is deprecated, and launchUrl does not support the forceWebView=false flag.

How do I run my url on default browser using url_launcher ?

TL;DR

You can use the LaunchMode.externalApplication parameter.

await launchUrl(_url, mode: LaunchMode.externalApplication);

More info

By default the mode value is set to LaunchMode.platformDefault , which in most cases is an inAppWebView .

Changing the mode solved this issue:

Future<void> openUrl(String url) async {
  final _url = Uri.parse(url);
  if (!await launchUrl(_url, mode: LaunchMode.externalApplication)) { // <--
    throw Exception('Could not launch $_url');
  }
}

LaunchMode support several arguments:

enum LaunchMode {
  /// Leaves the decision of how to launch the URL to the platform
  /// implementation.
  platformDefault,

  /// Loads the URL in an in-app web view (e.g., Safari View Controller).
  inAppWebView,

  /// Passes the URL to the OS to be handled by another application.
  externalApplication,

  /// Passes the URL to the OS to be handled by another non-browser application.
  externalNonBrowserApplication,
}
