Flutter 解决Column包裹GridView不显示问题

解决方式如下：

在ListView里面添加shrinkWrap:true,

ListView.builder(
                  
    shrinkWrap:true,
                  
    itemBuilder: (BuildContext context, int index) {

                    
        bool isSelected = index == _index;
                    
                    
        return _buildItems(
                        
            listname1[index], index,isSelected);

                  
        },

                  
    itemCount:listname1.length,

                
),
