)

## Implementation

    static Map<String, int> getDecodeMap(Encoding encoding) {
      var map = _decodeMap[encoding];
      if (map != null) {
        return map;
      } else {
        var chars = _encodeMap[encoding]!;
        // ignore: omit_local_variable_types
        Map<String, int> map = {};
        for (var i = 0; i < 32; i++) {
          map[chars[i]] = i;
        }
        _decodeMap[encoding] = map;
        return map;
