Flutter random word generator, nouns, verbs, names, sentences

Hi Guys, Welcome to Proto Coders Point, In this Flutter Article let’s checkout how to generate a random word in flutter dart. first by picking a randon word from a given list and second exampe by using a word_generator flutter library.

Generate random nouns example in flutter dart

Below is an dart program example to generate random nouns:

import 'dart:math';

void main() {
  List<String> nouns = [
    'Balloon',
    'Car',
    'Horse',
    'Raincoat',
    'Train',
    'Monkey',
    'Window',
    'Rocket',
    'Iron',
    'Girl'
  ];
  
  Random random = Random();
  int randomIndex = random.nextInt(nouns.length);
  String randomNoun = nouns[randomIndex];
  
  print(randomNoun);
}

In above Program we have a list of noun words created, Then we make use of Random class from math package that will generate a random number from 0 to the length of the list, and thus us use this random number and retrieve a noun list index and print it on console.

Flutter dart program to generate a random word

First add the dependency in your flutter project

open pubspec.yaml file and under dependencies section add:

dependencies:
  word_generator:
