This package is a collection of otherwise unrelated utilities that proved to be helpful to while creating Dart programs and Flutter apps.


Among the utilities implemented as of now, here are some of the notable ones:

  • Added string utility methods like toTitleCase and capitalize.
  • A cleaner class that performs cleanup on objects that need it.
  • Get the name of the enum without the preceding enum type name.
  • A range class the encapsulates minimum and maximum values.
  • Generate inclusive random numbers between any range.
  • <, <=, >, >= operators on the DateTime class.
  • A Cache class that caches outputs for inputs.
  • Truncate values from a DateTime instance.


Here's a few example uses for this package to get you up and running!

import 'package:handy/handy.dart';

enum Temperature {

void main() {
  print(; // hot
import 'package:handy/handy.dart';

void main() {
  final oneToTen = Range(1, 10);
  final outOfRange = 13;

  print(oneToTen.contains(outOfRange)); // false
  print(oneToTen.clamp(outOfRange)); // 10
  print(oneToTen.random()); // A random number between one and ten
import 'package:handy/handy.dart';

void main() {
  final title = "rayman 2: the great escape";

  print(title.toTitleCase()); // Rayman 2: The Great Escape
  print(title.capitalize()); // Rayman 2: the great escape
