Inside the Text widget add the overflow property:

 child: Text(label.toString(), overflow: TextOverflow.ellipsis,),

From the docs:

overflow → TextOverflow

How visual overflow should be handled.

I had to add isExpanded: true and overflow: TextOverflow.ellipsis.

SizedBox(
        width: 200.0,
        child:
          DropdownButtonFormField<String>(
            isExpanded: true,

            ...

            DropdownMenuItem(
              child: Text('YOUR_NAME',
                overflow: TextOverflow.ellipsis)

              ...
