UriData class

A way to access the structure of a data: URI.

Data URIs are non-hierarchical URIs that can contain any binary data. They are defined by RFC 2397.

This class allows parsing the URI text and extracting individual parts of the URI, as well as building the URI text from structured parts.

Constructors

UriData.fromBytes(List<int> bytes, { dynamic mimeType: "application/octet-stream", Map<String, String> parameters, dynamic percentEncoded: false })
factory
Creates a data: URI containing an encoding of bytes. [...]
UriData.fromString(String content, { String mimeType, Encoding encoding, Map<String, String> parameters, bool base64: false })
factory
Creates a data: URI containing the content string. [...]
UriData.fromUri(Uri uri)
factory
Creates a DataUri from a Uri which must have data as Uri.scheme. [...]
