Hi @AbdoTareq

Thanks for the PR and your hard work on the "GraphQL" support.

Unfortunately, I can not count on a package that is considered an Isolated "eco-system" because it provides a lot of unnecessary features that we won't need.

In brief, there is no need for those bunch of features just to add this small feature

I may suggest trying another package that focused on this specific feature "Json Viewer"

for example:
https://pub.dev/packages/flutter_json_view

Thanks again for the PR and I hope we reach a point where we can merge this PR into the main package ISA 😊🙏
