A RenderFlex overflowed by 125 pixels on the bottom-CodePudding

I am building a Flutter ecommerce app for delivery beverages. I am having an issue with my wishlist page. I am getting an error where it says "a Renderflex overflowed by 125 pixels at the bottom". The error is saying it is caused by the Column widget.I have tried different approaches including an Expanded widget as well as a Sizebox widget but with no luck. Please can anyone assist.

This shows that it is overflowed by 125 pixels at the bottom

Here's the code that's causing the error:

Container(
                height: 1500.0,
                width: double.infinity,
                child: Column(
                  children: [
                    const Text(
                      'My Favourites',
                      style: TextStyle(fontSize: 40.0),
                    ),
                    GridView.builder(
                      shrinkWrap: true,
                      itemCount: favItems.length,
                      itemBuilder: ((context, index) {
                        return ProductItem(
                            id: favItems[index].id,
                            bottleName: favItems[index].bottleName,
                            imgUrl: favItems[index].image,
                            price: favItems[index].price,
                            bottle: favItems[index]);
                      }),
                      gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
                        crossAxisCount: 2,
                        childAspectRatio: itemWidth / itemHeight,
                      ),
                    ),
                  ],
                ),
              ));

Wrap the GridView.builder with the Flexible widget. Column throws an exception because it doesn't know the height of the GridView

Container(
  height: 1500.0,
  width: double.infinity,
  child: Column(
    children: [
      const Text(
        'My Favourites',
        style: TextStyle(fontSize: 40.0),
      ),
      Flexible(child: 
        GridView.builder(
          shrinkWrap: true,
          itemCount: favItems.length,
          itemBuilder: ((context, index) {
            return ProductItem(
              id: favItems[index].id,
              bottleName: favItems[index].bottleName,
              imgUrl: favItems[index].image,
              price: favItems[index].price,
              bottle: favItems[index]);
          }),
          gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
            crossAxisCount: 2,
            childAspectRatio: itemWidth / itemHeight,
          ),
        )),
    ],
  ),
));
