Extender Dart #
Extender Dart
is a utility library for Dart developers. It offers a range of commonly used operations and aliases, including extensions for Lists and Maps to perform immutable add, remove, update, and insert operations. Designed to streamline everyday tasks, this library helps prevent accidental in-place modifications.
Features #
- Common Operations: Execute frequently-used operations with ease.
- Alias Collection: Simplify and accelerate your development with intuitive aliases for various data types, including time-based aliases for
int
and type conversion checks forString
. - List Extensions: Extend your Lists with immutable operations to prevent accidental in-place modifications.
- Map Extensions: Perform immutable operations on your Maps to prevent unintended in-place changes.
- Sort Operations: Easily sort your collections in various orders, including by property and with special handling for null values.

Aliases #
Int Aliases
These aliases allow you to use integers as durations with great simplicity.
import 'package:extender_dart/extender_dart.dart';
var fiveMinutes = 5.minutes; // Equivalent to Duration(minutes: 5)
var twoHours = 2.h; // Equivalent to Duration(hours: 2)
String Aliases
Make type conversions and validations a breeze with these string aliases.
import 'package:extender_dart/extender_dart.dart';
var integerValue = "123".toIntOrNull(); // Converts the string to integer, if valid
bool isItDouble = "12.34".isDouble; // Checks if the string is a valid double representation
var dateTimeValue = "2023-10-12T14:30:00Z".toDateTimeOrNull(); // Converts the string to DateTime, if valid
List Extensions #
import 'package:extender_dart/extender_dart.dart';
var myList = [1, 2, 3];
// Add an element immutably
var extendedList = myList.addWith(4); // [1, 2, 3, 4]
// Remove an element immutably
var reducedList = myList.removeWith(2); // [1, 3]
// Insert an element at a specific index immutably
var insertedList = myList.insertWith(1, 10); // [1, 10, 2, 3]
// Remove an element at a specific index immutably
var removedList = myList.removeAtWith(0); // [2, 3]
Map Extensions #
import 'package:extender_dart/extender_dart.dart';
var myMap = {'a': 1, 'b': 2};
// Add a key-value pair immutably
var extendedMap = myMap.addWith('c', 3); // {'a': 1, 'b': 2, 'c': 3}
// Add a MapEntry immutably
var extendedWithEntryMap = myMap.addEntryWith(MapEntry('d', 4)); // {'a': 1, 'b': 2, 'd': 4}
// Remove a key-value pair immutably
var reducedMap = myMap.removeWith('a'); // {'b': 2}
// Update a value for a key immutably
var updatedMap = myMap.updateWith('b', (value) => value * 2); // {'a': 1, 'b': 4}
Sort Operations #
Extender Dart
provides easy-to-use sorting utilities, making it simple to sort your lists in various orders.
Ascending & Descending
You can easily sort your lists in ascending or descending order.
import 'package:extender_dart/extender_dart.dart';
List<int> numbers = [1, 3, 5, 4, 2];
numbers.sort(SortOrder.asc); // [1, 2, 3, 4, 5]
numbers.sort(SortOrder.desc); // [5, 4, 3, 2, 1]
Property Sorting
For more complex types like Maps, you can pick a property to sort by.
List<Map<String, int>> persons = [
{"age": 20},
{"age": 30},
{"age": 10},
];
persons.sort(SortOrder.pick<Map>((e) => e["age"]).asc); // [{"age": 10}, {"age": 20}, {"age": 30}]
Handling Nulls
The library also provides utilities for sorting lists that contain null values.
List<int?> numbersWithNulls = [1, 3, null, null, 2];
numbersWithNulls.sort(SortOrder.nullsFirst); // [null, null, 1, 2, 3]
numbersWithNulls.sort(SortOrder.nullsLast); // [1, 2, 3, null, null]
Contributing #
Extender Dart
is an open-source project and is designed to be extensible. If you have ideas for new type extensions or improvements to existing ones, we warmly welcome your contributions. Not only are bug reports, feature requests, and questions appreciated, but we also encourage you to add extensions for other data types and share them with the community.
