UriData class Null safety
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 ofbytes
.factory -
UriData.fromString(String content, {String? mimeType, Encoding? encoding, Map<
String, String> ? parameters, bool base64 = false}) -
Creates a
data:
URI containing thecontent
string.factory - UriData.fromUri(Uri uri)
-
Creates a
DataUri
from a Uri which must havedata
as Uri.scheme.factory
