Flutter error: when using url_launcher plugin

Question

Future<void> launchInBrowser(String url) async {
  Uri dir = Uri.parse(url);
  if (!await launchUrl(
    dir,
    mode: LaunchMode.externalApplication,
  )) {
    throw 'Could not launch $url';
  }
}

I am using url_launcher version 6.1.6 flutter plugin and when I build the app I get this error flutter build is getting error with this : Could not load compiled classes for build file 'C:\src\flutter\flutter.pubcache\hosted\pub.dartlang.org\url_launcher_android_6.0.21\android\build.gradle' from cache '''

What went wrong: A problem occurred configuring project ':flutter_plugin_android_lifecycle'.

Could not load compiled classes for build file 'C:\src\flutter\flutter.pub-cache\hosted\pub.dartlang.org\url_launcher_android_6.0.21\android\build.gradle' from cache. Failed to notify project evaluation listener. Could not get unknown property 'android' for project ':url_launcher_android_6.0.21' of type org.gradle.api.Project. Could not get unknown property 'android' for project ':url_launcher_android_6.0.21' of type org.gradle.api.Project. '''

I tried deleting .gradle folder I'm my app , and also deleted the plugin from host folder , nothing works.

flutter doctor -v output

Did you add the following in your AndroidManifest.xml file?

<!-- Provide required visibility configuration for API level 30 and above -->
<queries>
  <!-- If your app checks for SMS support -->
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="sms" />
  </intent>
  <!-- If your app checks for call support -->
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="tel" />
  </intent>
</queries>

I received a lint error to use foreach instead. So I played around with it, and this is the final for loop:

prayerRequestList.forEach(prayerReturnList.add);
