A utility to create data URIs

Data URIs are generally of the format

  data:[mimeType][;charset=encoding][;base64],data

Further Reading on Data URI Scheme

Example Usage:

DataUri di = new DataUri(
  data: DataUri.base64EncodeString('test');
  mimeType: 'text/plain';
  encoding: 'utf-8');
di.toString(); # data:text/plain;charset=utf-8;base64,dGVzdA==

Constructors

DataUri({String mimeType = 'application/octet-stream', String encoding = '', String data = '', bool isDataBase64Encoded = true})

Construct a new DataUri. Assume that data is base64 encoded unless isDataBase64Encoded is passed in as false
