# replaceRange method

void replaceRange (int start, int end, Iterable<E> replacement)

Removes the objects in the range `start` inclusive to `end` exclusive and inserts the contents of `replacement` in its place.

    List<int> list = [1, 2, 3, 4, 5];
    list.replaceRange(1, 4, [6, 7]);
    list.join(', '); // '1, 6, 7, 5'

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.

This method does not work on fixed-length lists, even when `replacement` has the same number of elements as the replaced range. In that case use setRange instead.

## Implementation

    void replaceRange(int start, int end, Iterable<E> replacement);
