Range class

A numerical progression.

For basic usage, just provide the (exclusive) stop value - note that, by default, the range is exclusive of the stop value:

final range = Range(stop:5);
print(range.toList());

Result: [0, 1, 2, 3, 4]

Providing a start value allows for a non-zero starting point:

final range = Range(start: 1, stop:5);
print(range.toList());

Result: [1, 2, 3, 4]

Consider using the range() function if you just want to use a one-off range in a loop.
