      return filePath;
    } catch (e) {
      AppLogger.e(e);
    }
    return null;
  }
}

i try to define parameter but failed because still learning flutter

how i can solve this problem?

Answer 1

Since the version 10.0.0: onSelectNotification has been changed to onDidReceiveNotificationResponse as mentioned in the ChangeLog.md:

onDidReceiveNotificationResponse: invoked only when the app is running. This works for when a user has selected a notification or notification action. This replaces the onSelectNotification callback that existed before.

Answer 2

You have to use onDidReceiveNotificationResponse
