Json.fromDynamic(dynamic _rawValue, { bool initial = true, })

Create a Json instance from any value

Implementation

    } on JsonException catch (error) {

    }
  } else if (_rawValue is List) {
    List<dynamic> list = _rawValue as List<dynamic>;

    _rawValue = <dynamic>[];

    try {
      int i = 0;

        _set(i++, item);
      }
    } on JsonException catch (error) {
      exception = exception ?? error;
    }
  } else if (_rawValue is! int &&
