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() {
  final buf = StringBuffer();
  switch (severity) {
    case ValidationSeverity.error:
      buf.write('ERROR  ');
    case ValidationSeverity.warning:
      buf.write('WARN   ');
    case ValidationSeverity.info:
      buf.write('INFO   ');
    case ValidationSeverity.none:
      buf.write('OK     ');
  }
  if (filePath != null) {
    buf.write(filePath!);
    if (lineNumber != null) buf.write(':$lineNumber');
    buf.write('  ');
  }
  buf.writeln(message);
  if (fixSuggestion != null) {
    buf.writeln('       Fix: $fixSuggestion');
  }
  return buf.toString();
}
