Simple range iterator.

Basic Usage

range() method creates a Range object as follows:

range(1, 5);    // [1, 2, 3, 4]
range(1, 8, 2); // [1, 3, 5, 7]

Range class implements Iterable, so you can easily iterate over it:

range(0, 3).forEach((e) => print(e)); // 0, 1, 2

For creating detailed ranges, you have:

inclusiveRange(begin, end, [step]);  // [begin, end]
exclusiveRange(begin, end, [step]);  // (begin, end)
openClosedRange(begin, end, [step]); // (begin, end]
closedOpenRange(begin, end, [step]); // [begin, end)

You can also create a infinite range:

inifiniteRange(begin, [step]);      // [begin, infinity)
openInfiniteRange(begin, [step]);   // (begin, infinity)
closedInfiniteRange(begin, [step]); // same as infiniteRange 

If you need a type-specific range, please use:

range<int>(begin, end);
inclusiveRange<int>(begin, end);
range<double>(begin, end);
inclusiveRange<double>(begin, end);
// and so on



  • Enable Dart strong mode.


  • range methods now returns Range object instead of Iterable.
  • Support generic methods.
  • Remove non-generic methods.
