Throws an error unable to load assets there where I dont want any image – Flutter

I have a problem with passing image constructor. I passed one image there where I wanted and it automatically added something to the rest, when I didnt want it.

I try to pass it from here

    class LvPopup extends StatelessWidget {
  final String title;
  final String users_info;
  final String? image;
  LvPopup({
    super.key,
    required this.title,
    required this.users_info,
    this.image,
  });

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      child: Column(
        children: [
          SizedBox(height: 10),
          Column(
            children: [
              Row(
                children: [
                  Text(
                    title,
                    style: TextStyle(color: PaidworkColors.lightTxtColor),
                  ),
                ],
              ),
              SizedBox(
                height: 5,
              ),
              Row(
                children: [
                  Image.asset(image ?? ""),
                  Padding(
                    padding: const EdgeInsets.all(5.0),
                    child: Text(
                      users_info,
                    ),
                  ),
                ],
              )
            ],
          )
        ],
      ),
    );
  }
}

to there

LvPopup(
      title: 'E-mail',
      users_info: 'gmail.com',
    ),
    SizedBox(
      height: 5,
    ),
    LvPopup(
      users_info: 'Johny Bravo',
      title: 'Name and Surname',
    ),
    SizedBox(
      height: 5,
    ),
    LvPopup(
      image: 'assets/images/blue_dot.png',
      users_info: "In the process ",
      title: 'Status',
    ),
    SizedBox(
      height: 5,
    ),
    LvPopup(
      users_info: '+0.00',
      title: 'Earnings(USD)',
    ),

and the problem is that I want image only in:

 LvPopup(
  image: 'assets/images/blue_dot.png',
  users_info: "In the process ",
  title: 'Status',
),

but it throws an error to the rest and it says unable to load asset, when I dont want to pass image to the rest LvPopup only to that "Status"

here is an image:
