Classes

IterableRangeBounds

Range

A (half-open) range bounded inclusively below and exclusively above (start..end). The range contains all values with start <= x < end. It is empty if start >= end.

RangeBounds

RangeFrom

A range only bounded inclusively below (start..). Contains all values with x >= start. Note: This will not overflow, the last value yielded will be the largest possible int _intMaxValue.

RangeFull

An unbounded range (..). RangeFull is used as a slicing index, it cannot be used as an Iterable because it doesn’t have a starting point.

RangeInclusive

A range bounded inclusively below and above (start..=end). Contains all values with x >= start and x <= end. It is empty unless start <= end.

RangeIterator

RangeTo

A range only bounded exclusively above (..end). The RangeTo ..end contains all values with x < end. It cannot be used as an Iterable because it doesn’t have a starting point.

RangeToInclusive

A range only bounded inclusively above (..=end). The RangeToInclusive ..=end contains all values with x <= end. It cannot serve as an Iterable because it doesn’t have a starting point.

Functions

range(int startOrEnd, [int? end, int? step]) → Iterable<int>

A generator over a range by a step size. If end is not provided, the generated range will be [0..startOrEnd) if startOrEnd > 0, and nothing is generated otherwise. If step is not provided, step will be -1 if 0 > startOrEnd and 1 if 0 < startOrEnd. For reference, it works the same as the python range function.
