# addSlice method

void addSlice(

1. List<int> chunk,
2. int start,
3. int end,
4. bool isLast,

)

Adds the next `chunk` to `this`.

Adds the bytes defined by `start` and `end`-exclusive to `this`.

If `isLast` is `true` closes `this`.

Contrary to `add` the given `chunk` must not be held onto. Once the method returns, it is safe to overwrite the data in it.

## Implementation

    void addSlice(List<int> chunk, int start, int end, bool isLast) {
      add(chunk.sublist(start, end));
      if (isLast) close();
    }
