This package serves as an extension to many dart classes with the goal to provide a more fluid development experience
A library for adding many convenience methods / getters as extensions to commonly used dart classes.
#Iterable < int >
BigInt get sum #
- Calculates the sum of all the elements in the
Iterable
. - Runtime: O(n) where n is the size of the
Iterable
###BigInt get product
- Calculates the product of all the elements in the
Iterable
. - Runtime: O(n*m) where n is the number of elements in the
Iterable
, and m is the complexity ofBigInt
's*
operation (unknown at the moment)
###IntSummaryStatistics get stats
- Returns the summary stats for this iterable. Stats include, sum, product, max, min, count, and range
- Runtime: O(n*m) where n is the number of elements in the
Iterable
, and m is the complexity ofBigInt
's*
operation (unknown at the moment) - This is computed in one pass through the
Iterable
's elements
Usage #
A simple usage example:
import 'package:better/better.dart';
main() {
var r = Random();
var length = r.nextInt(1 << 12);
print('generating list...');
var list = [for(int i = 0; i < length; i++) r.nextInt(1 << 31)];
print('list generated');
print('calculating stats');
var start = DateTime.now().millisecondsSinceEpoch;
var stats = list.stats;
var end = DateTime.now().millisecondsSinceEpoch;
print('Finished calculating stats in ${end - start} ms');
print(stats);
}
