D20







D20 is a Dart library for RPG dice rolling. Supports standard notation (like "2d12", "d6+5" and "2d20-L").

One can also get (probably) useful information of roll results:
import 'package:d20/d20.dart';

void main() {
final d20 = D20();
final stats = d20.rollWithStatistics('2d8+5+5d6');
print(stats.results[0].faces);
print(stats.results[1].results);
}

Supported notation #
The standard dice notation will be parsed, such as 2d8+4.
L and H subtraction #
When a -L or -H follows a roll, as in 2d20-L, the lowest (or highest) roll of the sequence will be subtracted from the result.
Operators #
You can also use mathematical operators, such as 1d6*3 or 10d4/d6; or even 10 * sin(d20), though I'm not sure why you'd need that.
Percentile dice (d%) #
You can also use use the d% notation instead of d100.
