Issue with this

GridView.builder(
                              gridDelegate:
                                  const SliverGridDelegateWithFixedCrossAxisCount(
                                      crossAxisCount: 2),

Needed to add Shrinkwrap & Add the Ratio

      shrinkwrap: true,
      gridDelegate:
                              const SliverGridDelegateWithFixedCrossAxisCount(
                            crossAxisCount: 2,
                            childAspectRatio: 0.8,
                          ),

I am a beginner in flutter,

I changed to your code and working ok,

need a single line to be added to your code...

 gridDelegate: const SliverGridDelegateWithFixedCrossAxisCount(
          childAspectRatio: 1 / 1.5,//<- add this one (it will increase height of your card or container)
 crossAxisCount: 2),
