    You can define a global app name list. And push items into this list. After that, you can easily send it to the server. It will look like this:

    
  List<String> appNameList = List<String>();

  Future<void> getinstalledAppList() async {
    List<Application> apps = await DeviceApps.getInstalledApplications();

    apps.forEach((app) {
      var jsonList = app.appName;

      appNameList.add(app.appName); // Here we add them to a string list.
      print(jsonList);
    });
  }


  Future<void> callThisFunction(List<String> appNameList) async {
    // Here we can send the list to server
    await saveAppNameListToServer(appNameList);
  }

    You can use the following code which will extract appName from the application and make a list of it. You can directly write that list If you want JSON array in string format then you can make use of jsonEncode()

    var appNamesList = apps.map((app)=>app.appName).toList();
