or add this to your project's pubspec.yml:

dependencies:

Feature

• Interval - The interval data structure.
• IntervalSet - The interval merging.
• Interval & Interval - The interval intersection calculation
• Interval | Interval - The interval union calculation

Examples

• Simple example - Api example.

Usage

Create a Interval:

import 'package:dart_interval/dart_interval.dart';

final v1 = Interval.between(1, 3, lowerClosed: false, upperClosed: false);

Merge the intervals:

final v1 = Interval.between(1, 3);
final v2 = Interval.between(2, 5);
final v3 = Interval.between(7, 9);
final set = IntervalSet([v1, v2, v3]);
print(set);
// output: [1, 5],[7, 9]

Interval intersection calculation:

print(v1 & v2);
// output: [2, 3]

Interval union calculation:

print(v1 | v2);
// output: [1, 5]

or

print(IntervalSet([v1, v2]));
// output: [1, 5]
