如何在Laravel中检索ID？

我可以检索ID以外的其他用户详细信息。它在前端页面显示空值。

  @foreach($users as $row)
     <tr>
       <td>{{$row->id}}</td>
       <td>{{$row->name}}</td>
       <td>{{$row->username}}</td>
       <td>{{$row->email}}</td>
       <td>{{$row->usertype}}</td>
    </tr>
  @endforeach
</tbody>

create_users_table.php

    {
        Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('username')->unique();
            $table->string('email')->unique();
            $table->string('usertype');
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
        });
    }
