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

  • 💪 fully tested
  • 📝 well documented
  • 💼 enterprise-ready

⛏️ Getting started #

Add the dependency supercharged: ^1.0.0 to your project and start using Supercharged everywhere:

import 'package:supercharged/supercharged.dart';

For more details have a look at the install tab.

🌞 Highlights #

Transform any String to colors

"#ff00ff".toColor(); // painless hex to color
"red".toColor(); // supports all web color names

Helpful substring functions:

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

Parse user input:

"2.1".toDouble(); // 2.1
"42".toInt(); // 

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"] ]

More natural durations:

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

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"
});
