split static method Null safety

Iterable<String> split(
  1. String lines,
  2. [int start = 0,
  3. int? end]
)

Split lines into individual lines.

If start and end are provided, only split the contents of lines.substring(start, end). The start and end values must specify a valid sub-range of lines (0 <= start <= end <= lines.length).

Implementation

static Iterable<String> split(String lines, [int start = 0, int? end]) {
  end = RangeError.checkValidRange(start, end, lines.length);
  return _LineSplitIterable(lines, start, end);
}
