SliverGridDelegateWithFixedCrossAxisCount() not rendering

To Reproduce

Widget _productWidget() {
   return Container(
     margin: const EdgeInsets.symmetric(vertical: 10),
     width: AppTheme.fullWidth(context),
     height: AppTheme.fullWidth(context) * .7,
     child: GridView(
       gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
           crossAxisCount: 1,

           crossAxisSpacing: 0.0),
       padding: const EdgeInsets.only(left: 20),
       scrollDirection: Axis.horizontal,
       children: AppData.productList
           .map(
             (product) => ProductCard(
               product: product,
               onSelected: (model) {
                 setState(() {
                   AppData.productList.forEach((item) {
                     // item.isSelected;
                   });
                   // model.isSelected = true;
                 });
               },
             ),
           )
           .toList(),
     ),
   );
 }

renders me a black screen with the search bar atop. I have no idea what the issue could be. Thanks!

Describe the bug
A RenderFlex overflowed by 2.3 pixels on the bottom.

I added a semi-transparent black background for the picture. You can find that the background heights of the two pictures are different, which may cause errors in phones of different sizes.

So you can add "Expanded" and let it automatically adjust the height to avoid errors.

The build failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetifier to solve the incompatibility.
[!] Flutter tried to create the file android\settings_aar.gradle, but failed.
To manually update settings.gradle, follow these steps:
1. Copy settings.gradle as settings_aar.gradle
2. Remove the following code from settings_aar.gradle:

def properties = new Properties()
assert localPropertiesFile.exists()
