# Uri.dataFromBytes constructor

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

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

Defaults to Base64 encoding the bytes, but if `percentEncoded` is `true`, the bytes will instead be percent encoded (any non-ASCII or non-valid-ASCII-character byte is replaced by a percent encoding).

To read the bytes back, use UriData.contentAsBytes.

It defaults to having the mime-type `application/octet-stream`. The `mimeType` and `parameters` are added to the created URI. If any of these contain characters that are not allowed in the data URI, the character is percent-escaped. If the character is non-ASCII, it is first UTF-8 encoded and then the bytes are percent encoded.

## Implementation

    factory Uri.dataFromBytes(List<int> bytes,
        {mimeType = "application/octet-stream",
        Map<String, String> parameters,
        percentEncoded = false}) {
      UriData data = UriData.fromBytes(bytes,
          mimeType: mimeType,
          parameters: parameters,
          percentEncoded: percentEncoded);
      return data.uri;
    }
