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() {
final result = StringBuffer();
if (schemaName != null) {
result
..write(schemaName)
..write('.');
}
if (entityName != null) {
result
..write(entityName)
..write('.');
}
result.write(columnName);
return result.toString();
}
