[FIXED] Why Doesn't Work This Package On Flutter?

Issue

I want to use the url_launcher package. This package clearly runs on Android 11 virtual device but doesn't work on real Android 11 and Android 12 devices. However, it works on 9 and 7.

Here is my build.gradle configs

defaultConfig {
  // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
  applicationId "com.example.gelir_mii"
  // You can update the following values to match your application needs.
  // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
  minSdkVersion flutter.minSdkVersion
  targetSdkVersion flutter.targetSdkVersion
  versionCode flutterVersionCode.toInteger()
  versionName flutterVersionName
}

And here is the code block

void openWhatsapp() async {
  var whatsapp = '+9033823498234';
  var whatsappURL = Uri.parse(
    'whatsapp://send?phone=$whatsapp&text=Merhaba, danışmanlık hakkında bilgi almak istiyorum.');

  if (await canLaunchUrl(whatsappURL)) {
    await launchUrl(whatsappURL);
  } else {
    ScaffoldMessenger.of(context).showSnackBar(
      const SnackBar(
        content: Text("WhatsApp is not installed on the device"),
      ),
    );
  }
}

Thank you so much :)

Solution

Add any URL schemes passed to canLaunchUrl as entries in your AndroidManifest.xml, otherwise it will return false in most cases starting on Android 11 (API 30) or higher. A element must be added to your manifest as a child of the root element.

<!-- 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>

Please look at the pub config: https://pub.dev/packages/url_launcher
