removeRange method
override
Removes the objects in the range start
inclusive to end
exclusive.
The provide range, given by start
and end
, must be valid.
A range from start
to end
is valid if 0 <= start <= end <= len
, where
len
is this list's length
. The range starts at start
and has length
end - start
. An empty range (with end == start
) is valid.
Throws an UnsupportedError if this is a fixed-length list. In that case the list is not modified.
Implementation
void removeRange(int start, int end) {
RangeError.checkValidRange(start, end, this.length);
if (end > start) {
_closeGap(start, end);
}
}
