it helps some times You have some issues related to the Scroll of your widgets, you can reduce the amount of Widgets using Wrap, like this :
code :
    Container(
            color: Colors.white,
            padding: EdgeInsets.all(10),
            child: SingleChildScrollView(
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.stretch,
                mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                  new Text(
                    'Items of products',
                    style: TextStyle(fontWeight: FontWeight.w700, fontSize: 18.0),
                    textAlign: TextAlign.left,
                  ),
                  Padding(
                    padding: const EdgeInsets.only(top: 15.0),
                    child: Wrap(
                      spacing: 20.0,
                      alignment: WrapAlignment.spaceEvenly,
                      children:createCategoryList(),
                ),
                    ],
                ),
                )
            )
            ]
        ),
        );
    return Container(
          constraints:
                BoxConstraints(maxWidth: MediaQuery.of(context).size.width / 4),
          child: new GestureDetector(

Scrolling crashes program when scrolling through grid view

wish helps you Why does the for loop start at 1 and insert the data as it does? The NullPointerException is most likely caused by the for loop to insert Strings into the WordSearch Array.
eg.
code :
FormattedWords[0] = "a";
FormattedWords[1] = "b";
FormattedWords[2] = "c";
WordSearch[0] = "b";
WordSearch[1] = "c";
WordSearch[2] = null;
String [] WordSearch =  new String[FormattedWords.length - 1];

How can show grid view with other view in single page #flutter

I wish this helpful for you I think you should just set height of the Container or warp it by Expanded widget. And tell what happen?. Might be size is missing thats way error occurred.
EDITED :
code :
 body:ListView(
      children: <Widget>[
        Text("checking"),
        Container(
        height: 300.0
        child: GridView.count(
          crossAxisCount: 3,
          childAspectRatio: .6,
          children: _list.map((p) => ProductManagment(p)).toList(),
        ),
      ) 
      ],
    )

      separatorBuilder: (context, int) {
        return Divider(color: Colors.black,);
      },
     // shrinkWrap: true,
      itemBuilder: (BuildContext context, int index) {
        return GridView.count(
          shrinkWrap: true,
          crossAxisCount: 3,

                child: Text(
                  '$index AM',
                ),
              ),
            );
          }),
        );
      },
      itemCount: 4,
    ));
  }

Network images keeps disappearing when scrolling list view in flutter?


By : user2986722

may help you . List View creates the widget when it is visible. Thus only the visible child has the image and the one disappearing removes the widget and the one not loaded yet doesn't fetch the image. This approach has wonderful benefit of optimal memory utilization. Say you have 1000 of cards with images in List view and showing just 2-3 on the screen at the moment, thus only for the 2-3 visble card image will be loaded and when user will scroll and bring the other cards from the list, it will load images only when visible.
If you want to cache the images, please consider using package Cached_network_image
