Get content from txt file and put it in a list Flutter/Dart

Issue

this is my first question here on stackoverflow. Before i get into the question itself, i want to point out that i'm a beginner on Flutter and Dart and have no previous experience in mobile development.

Now, as the title says i'm having some issues while trying to extract the content of a text file and store the individual names inside the indexes of a list. The end goal of my application is to print a never ending list of these names, each separated to another by a comma. For example:

top model,
torcitóre,
torcolière,
tornitóre,
tosacàni,
tossicòlogo,
tour operator,
tracciatóre,
tranvière,
trattorìsta,
trattóre²,
trebbiatóre,
trecciaiòlo,
trevière,
tributarìsta,
trinciatóre,
trivellatóre,
truccatóre,
tubìsta,
turnìsta,

The text file, named jobs.txt contains more than a 1000+ italian job names. After several hours searching, all i have here is this (got from another user):

import 'dart:async';
import 'dart:convert';
import 'dart:io';

void main(List<String> arguments) {
  try {
    final _jobs = File('jobs.txt');

    List<String> lines = _jobs.readAsLinesSync(encoding: ascii);
    for (var l in lines) print(l);
  } catch (Exception) {
    print(Exception.toString());
    
  }
}

jobs.txt is inside the same directory as the dart file, which is bin.

While trying to give the _jobs variable the relative path:

FileSystemException: Cannot open file, path = 'binjobs.txt' (OS Error: Impossibile trovare il file specificato.
, errno = 2)

With absolute path:

FileSystemException: Cannot open file, path = 'C:UsersUserDesktopdartdart_application_injobs.txt' (OS Error: La sintassi del nome del file, della directory o del volume non è corretta.
, errno = 123)

For reasons i don't know, if that even matters, in the path specified in the error message, the \ look like they don't even exist.

By the way, this is my project structure: project structure

If your solution includes the usage of the Future class or async-await keywords, i'll be thankful if you could explain me how they work.

UPDATE: Look in the comments for the full solution to this issue. The verified answer isn't the full solution.

Solution

Create an assets folder in your project, in your pubspec.yaml specify the asset (make sure it's in your assets folder, that the file exists and is readable)

flutter:
  assets:
    - assets/jobs.txt

Now you can access your text file like so -

import 'dart:async' show Future;
import 'package:flutter/services.dart' show rootBundle;
Future<String> loadAsset() async {
  return await rootBundle.loadString('assets/jobs.txt');
}

When the function returns your text, you can split it by commas and loop through all the jobs as you wish
