Reading a file in dart and split the string has different results in console that in vscode

Question

I'm new in dart, I'm trying to read information from a txt file and use the data to create objects from a class (in this case about pokemon), but when I run my program in the terminal it doesn't prints the correct information, and when I run the program in vscode (whit the dart extension, the "run" button) it prints in the debug console the correct information. What is the problem?

When I run the program in vscode I get in my print method (printP) this (which is what I want)

vscode:

Print method:
1+: Bulbasaur GRASS | POISON

but when I run the program in the terminal I get this.

Terminal:

Print method:
 | POISONsaur

Here is the dart code.

main.dart

import 'dart:io';
import 'pokemon.dart';

void main() {
  var file = new File("/home/ariel/Documents/script/pokemon.txt");
  String str = file.readAsStringSync();
  var pokes = str.split("[");
  pokes = pokes.sublist(1, pokes.length);
  getPokemon(pokes[0]).printP();
}

Pokemon getPokemon(String str) {
  Pokemon p = new Pokemon();
  print("string: " + str);
  var aux = str.split("
");
  print(aux.length);
  for (var i in aux) {
    print("line: " + i);
  }
  p.number = int.parse(aux[0].split("]")[0]);
  p.name = aux[1].split("=")[1];
  p.type1 = aux[3].split("=")[1];
  p.type2 = aux[4].split("=")[1];
  return p;
}

pokemon.dart

class Pokemon {
  String _name, _type1, _type2;
  int _number;

  Pokemon() {
    this._name = "";
    this._number = 0;
    this._type1 = "";
    this._type2 = "";
  }

  void printP() {
    print("Print method:");
    print("${this._number}+: ${this._name} ${this._type1} | ${this._type2}");
  }

  void set number(int n) {
    this._number = n;
  }

  void set name(String nm) {
    this._name = nm;
  }

  void set type1(String t) {
    this._type1 = t;
  }

  void set type2(String t) {
    this._type2 = t;
  }
}

And here is the txt file

Your code are dependent on the newline format of your txt file. I will recommend you are using the LineSplitter class from dart:convert to split your lines.

The problem is that Windows newlines contains both ' ' and ' ' but you are only removing the ' ' part. ' ' are essential meaning the terminal should set the cursor back to the beginning of the line.

You can read this like a typewriter where you first move the head back and set move the paper to the next line. And can read a lot more about is topic here: https://en.wikipedia.org/wiki/Newline

The purpose of the LineSplitter class is to abstract all of this logic and get some behavior which will work on all platforms.

So import dart:convert and change this line:

var aux = str.split("
");

Into:

var aux = LineSplitter.split(str).toList();
