⚡️ Supercharged Dart #

Supercharged Dart brings all the comfort features from languages like Kotlin to all Dart developers.

💪 fully tested
📝 well documented
💼 enterprise-ready

⛏️ Getting started #

Add the dependency supercharged_dart: ^1.X.X (find recent version) to your project and start using Supercharged everywhere:

import 'package:supercharged_dart/supercharged_dart.dart';

🌞 Highlights #

Helpful substring functions:

"mode:production".allAfter(":"); // "production"
"<html>".allBetween("<", ">"); // "html"`
"flutter is cool".allBefore(" is"); // "flutter"

Handle user input:

"2.1".toDouble(); // 2.1
"42".toInt(); // 42
12.between(0, 30); // true

Effortless aggregation for Iterable<int> and Iterable<double>:

[1, 2, 3].sum(); // 6
[1, 2, 3].average(); // 2
[1, 2, 3].min(); // 1
[1, 2, 3].max(); // 3

Advanced aggregation for any Iterable:

var persons = [Person(age: 20), Person(age: 30), Person(age: 40)];
persons.sumBy((p) => p.age); // 90
persons.averageBy((p) => p.age); // 30
persons.count((p) => p.age < 35); // 2
persons.minBy((a,b) => a.age.compareTo(b.age)); // Person(age: 20)
persons.maxBy((a,b) => a.age.compareTo(b.age)); // Person(age: 40)

Safely access Iterable:

[].firstOrNull(); // return null instead
[].lastOrNull();  // of throwing error

[].firstOrElse(() => Placeholder()); // Produce default values
[].lastOrElse(() => Placeholder());  // on the fly

[1, 2, 3].elementAtOrNull(4); // Never go out of bounds
[1, 2, 3].elementAtOrElse(4, () => 0);

Group up data to match view:

var persons = [
    Person(name: "John", age: 21),
    Person(name: "Carl", age: 18),
    Person(name: "Peter", age: 56),
    Person(name: "Sarah", age: 61)
];

persons.groupBy(
    (p) => p.age < 40 ? "young" : "old",
    valueTransform: (p) => p.name
); // {"young": ["John", "Carl"], "old": ["Peter", "Sarah"]}

Chunking for easy pagination:

["a", "b", "c", "d", "e"].chunked(3); // [ ["a", "b", "c"], ["d", "e"] ]
["a", "b", "c"].chunked(2, fill: () => ""); // [ ["a", "b"], ["c", ""] ]

More natural durations and dates:

var duration = 5.minutes + 30.seconds;
duration += 0.5.hours;

var future = 2.days.fromNow() + 20.minutes;
var past = 15.minutes.ago();

var allDaysOf2020 = DateTime(2020).until(DateTime(2021));
var allFullHoursOfFirstJanuary2020 =
  DateTime(2020, 1, 1).until(DateTime(2020, 1, 2), by: 1.hours);

Simplified data sorting:

 persons = [
    Person(name: "John", age: 21),
    Person(name: "Carl", age: 18),
    Person(name: "Peter", age: 56),
    Person(name: "Sarah", age: 61)
  ];

  persons.sortedByNum((p) => p.age); // list sorted by age
  persons.sortedByString((p) => p.name); // list sorted by name
  persons  // sorted with comparator
      .sortedBy((a, b) => a.name.compareTo(b.name));

  persons // sorting is fully integrated into processing chain
      .filter((p) => p.name.length < 5)
      .sortedByNum((p) => p.age)
      .map((p) => p.name)
      .toList();

Replace your classic for-loop:

0.rangeTo(5); // [0, 1, 2, 3, 4, 5]
3.rangeTo(1); // [3, 2, 1]

var list = ["dog", "cat", "mouse"];
0.until(list.length); // [0, 1, 2]

list.forEachIndexed((index, value) {
    // index: 0, value: "dog"
    // index: 1, value: "cat"
    // index: 2, value: "mouse"
});
