toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  String base64 = string;
  if (base64 == '') {
    Uint8List? bin = binary;
    if (bin != null) {
      base64 = Base64.encode(bin);
      string = base64;
    }
    assert(base64.isNotEmpty, 'failed to encode base64 data: ${bin?.length} byte(s)');
  }
  return base64;
}
