How to convert String List to String in flutter?

Question

I need to convert List<String> into a String in the dart.

I want to extract the value of the list from preferences. I have tried this implementation but it is only giving me the last value.

Future<List<String>> services = SharedPrefSignUp.getSelectedServices();
services.then((onValue){
  List<String>servicesList=onValue;
  selectServicesText=servicesList.join(",");
});

You can iterate list and concatenate values with StringBuffer

  var list = ['one', 'two', 'three'];
  var concatenate = StringBuffer();

  list.forEach((item){
    concatenate.write(item);
  });

  print(concatenate); // displays 'onetwothree'

  }
