This repository contains a collection of useful extension methods on the built-in objects in Dart, such as String, Iterable, and Object.

Usage

Import the basics library.

import 'package:basics/basics.dart';

Then use the methods directly on objects in your dart code.

import 'package:basics/basics.dart';

main() async {
  const numbers = <int>[2, 4, 8];

  if (numbers.all((n) => n.isEven)) {
    print('All numbers are even.');
  }

  print('sum of numbers is: ${numbers.sum()}');

  for (var _ in 5.range) {
    print('waiting 500 milliseconds...');
    await Future.delayed(500.milliseconds);
  }
}
