toString method
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 txt = string;
if (txt == '') {
Uint8List? bin = binary;
if (bin != null) {
txt = UTF8.decode(bin) ?? '';
string = txt;
}
assert(txt.isNotEmpty, 'plain data error: $bin');
}
return txt;
}
