toString method Null safety

  1. @override
String toString(
  1. {DiagnosticLevel minLevel = DiagnosticLevel.info}
)
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 represetion.

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({DiagnosticLevel minLevel = DiagnosticLevel.info}) {
  final String debugDescription = this.debugDescription;
  if (minLevel.index >= DiagnosticLevel.info.index && debugDescription != null)
    return debugDescription;
  return super.toString(minLevel: minLevel);
}
