toString method Null safety
override
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() {
final StringBuffer result = StringBuffer();
result.write('TableRow(');
if (key != null) {
result.write('$key, ');
}
if (decoration != null) {
result.write('$decoration, ');
}
if (children == null) {
result.write('child list is null');
} else if (children!.isEmpty) {
result.write('no children');
} else {
result.write('$children');
}
result.write(')');
return result.toString();
}
