flutter GridView + Card, Text Bottom overflow problem

I am using the card widget in GridView. We are going to add several widgets at the bottom of the card widget. TextOverflow.ellipsis option doesn't work.

Please refer to the image in question. I tried several methods but couldn't fix it.

Please tell me how to fix it. And, can it be made using grid tiles?

Below is the source code.

GridView.builder(
            //shrinkWrap: true,                
            itemCount: slpProduct.length,
            itemBuilder: (BuildContext _context, int index) {               
                 
              return Column(
                mainAxisAlignment: MainAxisAlignment.start,
                children: [
                  Card(
                    clipBehavior: Clip.antiAlias, // 
                    elevation: 0.5,                        
                    color: Colors.white,
                    child: Container(
                        width: 300.0,
                        child: Expanded(
                          child: Column(
