toString method

@override String toString()

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() {
  if (hoverInfo != null) return hoverInfo!;
  if (diagnostics != null && diagnostics!.isNotEmpty) {
    return diagnostics!
        .map(
          (d) =>
              '${d['severity']}: ${d['message']} (${d['line']}:${d['column']})',
        )
        .join('\n');
  }
  if (results != null && results!.isNotEmpty) {
    return const JsonEncoder.withIndent('  ').convert(results);
  }
  return 'No results';
}
