range type

Range package for Dart #
The convenient pure Dart library of ranges representation. Range types are data types representing a range of values of some element type.
Examples #
Creation of a range
// common way
var range = IntRange(
lowerBound: Bound(type: BoundType.inclusive, value: 1),
upperBound: Bound(type: BoundType.exclusive, value: 10),
);

// through parsing from a string
range = IntRange.parse('[1, 10)');

// through an extension
range = 1.range(10);
copied to clipboard
Checking for an element in the range
var range = IntRange.parse('[1, 10)');

// common way
if(range.containsElement(7)) {
print('contains');
}

// through an extension
if(7.contained(range)) {
print('contains');

final scheduleDate2 = DateTime(2022, 08, 07);

final workingDays = DateTimeRange.parse('[2022-07-20, 2022-08-15)');

print('Is scheduleDate1 in July? ${july.containsElement(scheduleDate1)}');
print('Is scheduleDate2 in July? ${july.containsElement(scheduleDate2)}');
print('Is workingDays overlaps? ${july.overlap(workingDays)}');
print('workingDays intersection: ${july.intersection(workingDays)}');
print('workingDays union: ${july.union(workingDays)}');
print('july difference workingDays: ${july.difference(workingDays)}');
