how Can I I embed instagram code in flutter web project?

I am searching for a way in which I can include the embed code from Instagram to fetch public post and display it on my screen...I tried many packages from pub.dev like flutter_html_view and in this package, you have to run the project without null safety so I skipped it. I tried this method too ui.platformViewRegistry.registerViewFactory () but there is no response and nothing to display to the browser. so how can I implement this embed code and show it on the screen of my browser? please help! This is what is shown whenever I tried to fetch the embed code This is the embed code that I meant which I want to implement
