# removeRange method

void removeRange(

1. int start,
2. int end

)
override

Removes a range of elements from the list.

Removes the elements with positions greater than or equal to `start` and less than `end`, from the list. This reduces the list's length by `end - start`.

The provided range, given by `start` and `end`, must be valid. A range from `start` to `end` is valid if 0 ≤ `start` ≤ `end` ≤ length. An empty range (with `end == start`) is valid.

The list must be growable.

    final numbers = <int>[1, 2, 3, 4, 5];
    numbers.removeRange(1, 4);
    print(numbers); // [1, 5]

## Implementation

    void removeRange(int start, int end) {
      throw new UnsupportedError("Cannot removeRange on immutable List.");
    }
