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() {
  String SEP = "\n";
  StringBuffer sb = StringBuffer();
  sb.write("=== RowData ===" + SEP);
  bool isFirst = true;
  _fieldNamesMap.forEach((k, v) {
    if (!isFirst) sb.write(", ");
    sb.write("$k=");
    sb.write(getField(v).toString());
    isFirst = false;
  });
  sb.write(SEP);
  return sb.toString();
}
