lookaround_iterator 1.0.1+1
Dart lookaround iterator #
The LookaroundIterator
class exposes a fixed number of elements in the past and future of the current iteration element.
// `it` is an iterator over a list of the numbers 1..10, currently
// pointing at `4`.
final it = LookaroundIterator(
List.generate(10, (n) => n + 1).iterator,
lookbehind: 2,
lookahead: 3)
..moveNext()
..moveNext()
..moveNext()
..moveNext();
// Prints _2, 3, 4, 5, 6, 7_.
// Notice the negative start index and the inclusive range `<=`.
for (int i = -it.lookbehind; i <= it.lookahead; i++) {
print(it[i]);
}
