UriData class - dart:core library (original) (raw)
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, extracting individual parts of the URI, as well as building the URI text from structured parts.
Constructors
UriData.fromBytes(List<int> bytes, {String mimeType = "application/octet-stream", Map<String, String>? parameters, bool percentEncoded = false})
Creates a data: URI containing an encoding of bytes.
factory
UriData.fromString(String content, {String? mimeType, Encoding? encoding, Map<String, String>? parameters, bool base64 = false})
Creates a data: URI containing the content string.
factory
UriData.fromUri(Uri uri)
Creates a DataUri from a Uri which must have data as Uri.scheme.
factory
