initialize static method Null safety

Future initialize(
  1. PayooVnSettings settings

Need to call this method before starting using Payoo's features. This method could be called at initialize state of application or a screen that uses Payoo's features. It's ok to be called multiple times.


static Future<dynamic> initialize(PayooVnSettings settings) async {
  var settingsMap = settings.toMap();
  debugPrint('PayooVnPlugin.initialize: $settingsMap');
  return await _channel.invokeMethod('initialize', settingsMap);
