Invalid notification (no valid small icon)

[hsnbsst]

Although we tried all the methods we found here and on the internet, we could not solve the problem. There was a problem with the plugin.

Future<void> initializeLocalNotification() async {
  tz.initializeTimeZones();

  tz.setLocalLocation(tz.getLocation('America/Detroit'));

  const AndroidInitializationSettings initializationSettingsAndroid =
      AndroidInitializationSettings('ic_stat_rcicon');

  const InitializationSettings initializationSettings = InitializationSettings(
    android: initializationSettingsAndroid,
  );

  await _flutterLocalNotificationsPlugin.initialize(
    initializationSettings,
    onSelectNotification: (_) {},
  );
}

Sample code to reproduce the problem

If you believe the issue with the plugin then please provide a link to a repository hosting a minimal app that can reproduce the issue. One question I do have though is do you experience the issue with the debug builds?

Closing due to lack of response to provide the information that has been requested. If you can do so then feel free to re-open the issue
