I didn't test it but this should work,all you have to do is style the widgets in the Row widget according to the image you put

 showAlertDialog(BuildContext context) {
    AlertDialog alert = AlertDialog(
 
      content: Container(
          child: Row(
             children:[
                 Expanded(
                    child: TextField(
                          decoration: InputDecoration(
                    hintText: "First Name",
                        ),
                     ),
                  ),
                 Expanded(
                    child: TextField(
                          decoration: InputDecoration(
                    hintText: "Last Name",
                       ),
                     ),
                  ),
             ]
          ),
       ),
    );

    // show the dialog
    showDialog(
      context: context,
      builder: (BuildContext context) {
        return alert;
      },
    );
  }

For a column to form in an alert dialog box you have put the textfield in an expanded widget.

 Row(children: [
                Expanded(
                    child: TextField(),
                ),
               SizedBox(width: 8.0,),
               Expanded(
                   child: TextField(),
               ),
    ]),
