Hi Harsha, great question. I haven't tried it yet but I found an example inside the json_dynamic_widget examples Library using sliver_list

Here's the link for it

https://github.com/peiffer-innovations/json_dynamic_widget/blob/main/json_dynamic_widget/example/assets/pages/slivers.json

inthe mean while I would also like to try this and make another it available for you..

Thanks and happy coding
