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 prefix = switch (severity) {
DiagnosticSeverity.error => '❌',
DiagnosticSeverity.warning => '⚠️',
DiagnosticSeverity.info => 'ℹ️',
};
final providerStr = provider != null ? '[${provider!.displayName}] ' : '';
return '$prefix $providerStr$message';
}
