⛏️ Getting started #
Add Supercharged to your project by following the instructions on the install page.
💡 Hint: You can type Superch and press CTRL + Space for code completion to trigger auto-import:
🌞 Highlights #
Transform any String to colors
"#ff00ff".toColor(); // painless hex to color
"red".toColor(); // supports all web color names
Helpful string 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 (now supported by Dart collection package)
[1, 2, 3].average; // 2 (now supported by Dart collection package)
[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; // (now supported by Dart collection package)
[].lastOrNull; // (now supported by Dart collection package)
[].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);
[1, 2, 3].pickOne(); // Get a random item
[1, 2, 3].pickSome(2); // or multiple random items
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);
await 2.seconds.delay; // waits for 2 seconds
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.sortedBy<num>((p) => p.age); // (now supported by Dart
persons.sortedBy<String>((p) => p.name); // collection package)
persons
.where((p) => p.name.length < 5)
.sortedBy<num>((p) => p.age)
.onEach(print)
.map((p) => p.name)
.toList();
Solid tween shortcuts for animations:
100.0.tweenTo(200.0); // Tween(begin: 100.0, end: 200.0)
Colors.red.tweenTo(Colors.blue); // ColorTween(...)
0.0.tweenTo(100.0).curved(Curves.easeInOut); // Apply acceleration
Offset(50, 50).tweenTo(Offset.zero); // Offset-Tween
Size(400, 300).tweenTo(Size.square(50)) // Size-Tween
Rect.zero.tweenTo(Rect.fromLTWH(50, 50, 400, 300)) // Rect-Tween
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) { // (now supported by Dart collection package)
// index: 0, value: "dog"
// index: 1, value: "cat"
// index: 2, value: "mouse"
});
