How to split string and put each line in element array in Dart?

Question

I want to split some string and to contain each line in separate element in array. I use this code for reaching my goal:

List _masForUsing;
_masForUsing = new List(numberOfLines);

    void gpsHelper(String text, int count){
        for(int i =0; i<count;i++){
          _masForUsing[i] = text.split("\\r?\\n");
        }
        print(_masForUsing[2]);
      }

But when I am truying to evoke the third element of array, it just show full my string. Please help, me :)

This is example of String:

real time: 23-09-2019, 23:08:55, Mon 
system time: 5362 
gps coordinates: 55.376538; 037.431973; 
gps satellites: 3; 
gps time: 20:09:02; 
gps date: 23.09.19;
temperature: 19 *C 
humidity: 35 %  
dust: 1 
zivert: 21

Your split argument is a string, but you are expecting it to be a regular expression. It doesn't match because your string does not contain the five-letter substring "BACKSLASH r QUESTIONMARK BACKSLASH n". To use it as a RegExp, you have to write text.split(RegExp("\\r?\\n")) (or, more readable: text.split(RegExp(r"\r?\n")) using a raw string). Or use the available StringSplitter as recommended below. — lrn

Use Dart's built in LineSplitter, It is system independent.

void gpsHelper(String text) {
   LineSplitter ls = new LineSplitter();
   List<String> _masForUsing = ls.convert(text);

    //print(_masForUsing[2]); // gps coordinates: 55.376538; 037.431973;
}

If anyone wonders, you need to import 'dart:convert';

Is this what you want?

void gpsHelper(String text) {
  List _masForUsing = text.split("\n");//this one here

  print('third string is ${_masForUsing[2]}');
}
