chunks method
Splits string by chunks with specified size
.
If string is empty than empty Intarbale
will be returned.
If size
less or equal 0, that ArgumentError will be raised.
Implementation
Iterable<String> chunks(int size) sync* {
if (isEmpty) return;
if (size <= 0) {
throw ArgumentError.value(size, 'size', 'Should be more than zero');
}
final total = length;
if (total <= size) {
yield this;
} else {
var start = 0;
do {
final end = start + size;
yield substring(start, min(end, total));
start = end;
} while (start < total);
}
}
