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 infos = Map<String, dynamic>.fromEntries(
      details?.entries.where((element) => element.value != null) ?? []);
  if (infos.isEmpty) {
    if (errorCode == null) {
      return 'RPCError: $message';
    }
    return 'RPCError: got code $errorCode with message "$message".';
  }
  final String msg =
      "$message ${infos.entries.map((e) => "${e.key}: ${e.value}").join(", ")}";
  if (errorCode == null) {
    return 'RPCError: $msg';
  }
  return 'RPCError: got code $errorCode with message "$msg".';
}
