lindex method

Future<String?> lindex(String key, int index)

Returns the element at index index in the list stored at key. The index is zero-based, so 0 means the first element, 1 the second element and so on. Negative indices can be used to designate elements starting at the tail of the list. Here, -1 means the last element, -2 means the penultimate and so forth.

When the value at key is not a list, an error is returned.

Returns the requested element, or nil when index is out of range.

Implementation

Future<String?> lindex(String key, int index) async {
  return (await tier1.lindex(key, index)).toBulkString().payload;
}
