    Is the .map() at Flutter is the same with Javascript, my API call is List, and it's can't work at .map(), very confusing

    • @FlutterExplained
      @FlutterExplained  2 года назад

      Hi there, yes the .map() function is quite similar the equivalent of a JavaScript Array is the List in Dart. Therefore you are able to work in there nearly the same way. I hope that clears things up :)

    1:20.. Who will provide num parameter to that function ? Can u plz tell me

    • @FlutterExplained
      @FlutterExplained  2 года назад

      Sure, the List is a List of numbers (List) if you use "map" now on that List you will need to pass in a method that gets called every time when the pointer goes from one number to another number.
      [>12 (12) => 12 * 2; // returns a array [24]
      [12, >15 (15) => 15 * 2; // returns a array [24, 30]
      [12, 15, >16 (16) => 16 * 2; // returns a array [24, 30, 32]
      >12< represents the pointer
      But because we do not want to write 3 times the function we can use the .map function. I hope that made it a bit clearer for you :)

      There are couple of methods that you can use to remove an element in a list. You can use .remove(), .removeAt() or removeWhere() etc. www.woolha.com/tutorials/dart-removing-elements-from-list-examples
