stringify method

String stringify(Object? value)

Implementation

String stringify(Object? value) {
  if (value == null) return 'null';
  if (value is bool) return value.toString();
  if (value is InterpretedInstance) {
    // Dispatch to the user-defined toString() method if present so string
    // interpolation honours overrides like `class Foo { String toString() => ... }`.
    final toStringMethod = value.klass.findInstanceMethod('toString');
    if (toStringMethod != null) {
      Object? result;
      try {
        result = toStringMethod
            .bind(value)
            .call(this, const <Object?>[], const <String, Object?>{});
      } on ReturnException catch (e) {
        result = e.value;
      }
      if (result is String) return result;
      if (result == null) return 'null';
      return result.toString();
    }
  }
  return value.toString();
