You can try this code blocks

CustomScrollView(
            scrollDirection: Axis.vertical,
            slivers: [
              SliverFillRemaining(
                hasScrollBody: false,
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                  children: [
                    Text('test'),
                    for (int i = 0; i < 10; i++) const FlutterLogo(size: 80)
                  ],
                ),
              ),
            ],
          ),
