# UriData.fromBytes constructor

UriData.fromBytes(List<int> bytes, { dynamic mimeType: "application/octet-stream", Map<String, String> parameters, dynamic percentEncoded: false })

Creates a `data:` URI containing an encoding of `bytes`.

Equivalent to `new Uri.dataFromBytes(...).data`, but may be more efficient if the uri itself isn't used.

## Implementation

    factory UriData.fromBytes(List<int> bytes,
        {mimeType: "application/octet-stream",
        Map<String, String> parameters,
        percentEncoded: false}) {
      StringBuffer buffer = new StringBuffer();
      List<int> indices = [_noScheme];
      _writeUri(mimeType, null, parameters, buffer, indices);
      indices.add(buffer.length);
      if (percentEncoded) {
        buffer.write(',');
        _uriEncodeBytes(_uricTable, bytes, buffer);
      } else {
        buffer.write(';base64,');
        indices.add(buffer.length - 1);
        _base64.encoder
            .startChunkedConversion(
                new StringConversionSink.fromStringSink(buffer))
            .addSlice(bytes, 0, bytes.length, true);
      }

      return new UriData._(buffer.toString(), indices, null);
    }
