How to fetch a random mention from the model? - dart

Question

I'm new to model writing and I need your help.
I write a code like this:
import 'dart:js';
import 'dart:math';
List AllWords = [{"ID": 0, "Word": "This is words.", "Author": "Emir"}, {"ID": 1, "Word": "This is words.", "Author": "Jack"}];
class Words {
final int ID;
final String Word;
final String Author;
Words(this.ID, this.Word, this.Author);
void GetWords() {
final _random = new Random();
var Words = AllWords[_random.nextInt(AllWords.length)];
return Words;
}
}
My goal is to fetch a random word from the list when I use the GetWords Function. Is this code correct? How can I use this code I wrote in main.dart?
Thanks for help.

try this :
import 'dart:math' as math;
//your list is a map, not a `Words` class
//if your list is a `Words` class, it will be like this :
//final allWords = [Words(Id,words,author), Words()}
List<Map<String, Object?>> allWords = [
{"ID": 0, "Word": "This is words.", "Author": "Emir"},
{"ID": 1, "Word": "This is words.", "Author": "Jack"}
];
class Words {
final int iD;
final String word;
final String author;
Words({required this.iD, required this.author, required this.word});
factory Words.fromJson(Map<String, Object?> json) {
return Words(
iD: json['ID'] as int,
author: json['Author'] as String,
word: json['Word'] as String);
}
factory Words.getRandomWord() {
math.Random random = math.Random();
return Words.fromJson(allWords[random.nextInt(allWords.length - 1)]);
}
}
//Somewhere else in your code
Words myWord = Words.getRandomWord();
