Please explain a simple example of CRUD operations, because after updating the new flutter (v2.10) and Strapi (v4.1.7) , I did not find resources that explain this at all, whether in English or Arabic, All existing Resources are old and explain to old versions , and I no longer have the ability to make successful communication between them in these four operations because of this update, which led to a change in the format of the codes used for it plz help me and thank you
