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 buff = StringBuffer('$severity $code: $message ');
if (detail != null) {
buff.write('Detail: $detail ');
}
if (hint != null) {
buff.write('Hint: $hint ');
}
if (tableName != null) {
buff.write('Table: $tableName ');
}
if (columnName != null) {
buff.write('Column: $columnName ');
}
if (constraintName != null) {
buff.write('Constraint $constraintName ');
}
return buff.toString();
}
