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();
}
