ERROR:flutter/runtime/dart_vm_initializer.cc(41) on url

I use HTTP launcher and found this error on my console log after I run debug on my android studio emulator:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method launch on channel plugins.flutter.io/url_launcher_android)

This is the code where it throw error:

Future<void> _launchMap() async {
    final url = widget.website;
    var uri = Uri.parse(url);
    if (!await launchUrl(uri)) {
      throw 'Could not launch';
    }
  }

this is my android manifest:

       <queries>
            <!-- If your app checks for call support -->
            <intent>
                <action android:name="android.intent.action.VIEW" />
                <data android:scheme="tel" />
            </intent>
            <intent>
                <action android:name="android.intent.action.VIEW" />
                <data android:scheme="https" />
            </intent>
        </queries>

I use the newest flutter version and I already follow the guide from https://pub.dev/packages/url_launcher, but it still can't direct the link that I want from my API

CodePudding user response：

If you are using hot restart or hot reload, it won't do the trick. Since Flutter has to inject plugin dependencies into the platform-specific parts of your app, hot restart/hot reload is not enough to trigger the injection. Check this issue for more.

Close the app and execute flutter run command.

Try below code

Future<void> _launchMap() async {
       final url = widget.website;
       var uri = Uri.parse(url);
    if (await canLaunchUrl(url)) {
       await launchUrl(url);
   } else {
       throw 'Could not launch $url';
}}
