String convert (

1. List<int> input

)
override

Converts `input` and returns the result of the conversion.

## Implementation

    String convert(List<int> input) {
      if (input.isEmpty) return "";
      var encoder = _Base64Encoder(_urlSafe);
      var buffer = encoder.encode(input, 0, input.length, true)!;
      return String.fromCharCodes(buffer);
    }
