# operator [] method

String operator [](

1. int index

)
override

The object at the given `index` in the list.

The `index` must be a valid index of this list, which means that `index` must be non-negative and less than length.

## Implementation

    String operator [](int index) {
      if (JS("bool", "# >>> 0 !== # || # >= #", index, index, index, length))
        throw new IndexError.withLength(index, length, indexable: this);
      return this.getItem(index);
    }
