Scroll through Flutter Bottom Sheet

I’ve found a solution implementing the code below

void _showBottomSheet(BuildContext context) {
showModalBottomSheet(
  context: context,
  isScrollControlled: true,
  backgroundColor: Colors.transparent,
  builder: (context) {
    return GestureDetector(
      onTap: () => Navigator.of(context).pop(),
      child: Container(
        color: Color.fromRGBO(0, 0, 0, 0.001),
        child: GestureDetector(
          onTap: () {},
          child: DraggableScrollableSheet(
            initialChildSize: 0.4,
            minChildSize: 0.2,
            maxChildSize: 0.75,
            builder: (_, controller) {
              return Container(
                decoration: BoxDecoration(
                  color: Colors.white,
                  borderRadius: BorderRadius.only(
                    topLeft: const Radius.circular(25.0),
                    topRight: const Radius.circular(25.0),
                  ),
                ),
                child: Column(
                  children: [
                    Icon(
                      Icons.remove,
                      color: Colors.grey[600],
                    ),
                    Expanded(
                      child: ListView.builder(
                        controller: controller,
                        itemCount: 100,
                        itemBuilder: (_, index) {
                          return Card(
                            child: Padding(
                              padding: EdgeInsets.all(8),
                              child: Text("Element at index($index)"),
                            ),
                          );
                        },
                      ),
                    ),
                  ],
                ),
              );
            },
          ),
        ),
      ),
    );
  },
 );
}
