if you know you have List<String>
then you can use join()
function provided by a flutter.
var list = ['one', 'two', 'three'];
var stringList = list.join("");
print(stringList); //Prints "onetwothree"
Simple and short. 😉
And you can use it like this:
List<String> servicesList = ["one", "Two", "Thee"];
print(servicesList.join(""));
