- 💪 fully tested
- 📝 well documented
- 💼 enterprise-ready
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.
Transform any String to colors
"#ff00ff".toColor(); // painless hex to color
"red".toColor(); // supports all web color namesHelpful 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(); // 3Advanced 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"
});You can discover all 58 features in the API documentation. Each feature is well documented with an example.
