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 buffer = StringBuffer('SqliteException(')
    ..write(extendedResultCode)
    ..write('): ')
    ..write(operation == null ? '' : 'while $operation, ')
    ..write(message);

  if (explanation != null) {
    buffer
      ..write(', ')
      ..write(explanation);
  }

  if (causingStatement != null) {
    buffer
      ..writeln()
      ..write('  Causing statement')
      ..write(offset != null ? ' (at position $offset): ' : ': ')
      ..write(causingStatement);

    if (parametersToStatement != null) {
      final params = parametersToStatement!.map((e) {
        if (e is Uint8List) {
          return 'blob (${e.length} bytes)';
        } else {
          return e.toString();
        }
      }).join(', ');
      buffer.write(', parameters: $params');
    }
  }

  return buffer.toString();
