# Uri.dataFromBytes constructor

Uri.dataFromBytes(

1. List<int> bytes, {
2. String mimeType = "application/octet-stream",
3. Map<String, String>? parameters,
4. bool 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.

Example:

    final uri = Uri.dataFromBytes([68, 97, 114, 116]);
    print(uri); // data:application/octet-stream;base64,RGFydA==

## Implementation

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