Flutter how to convert String to List<String>

Question

I have this String.

  var String a = '["one", "two", "three", "four"]';
  var ab = (a.split(','));
  print(ab[0]); // return ["one"

I want to convert this to List<String>. The problem is it returns square bracket too. I want to List looks this ["one", "two", "three", "four"] not [["one", "two", "three", "four"]]. How can I convert this properly?

Answer 1

Your string looks like a valid JSON, so this should work for you:

import 'dart:convert';
...

var a = '["one", "two", "three", "four"]';
var ab = json.decode(a);
print(ab[0]); // returns "one"

Answer 2

void main(){
     String listA = '["one", "two", "three", "four"]';
     var a = jsonDecode(listA);
     print(a[0]); // print one

     String listB = 'one,two,three,four';
     var b = (listB.split(','));
     print(b[0]); // print one
}
