flutter web show html code example

Example: flutter web show html

There is a HTMLElementView widget which can help you embed Html in 
flutter web. This widget can take an Iframe and render it. 

If you don't prefer Iframe then you can embed simply a BodyElement 
from the dart:html library directly.

An example of embedding Iframe is availabel here. Eventhough its from
an old repo, the code is valid and I couldn't find a latest one.

If you don't want do go the tough way, there is simplified widget from 
Rodydavis which is available here called easy_web_view.

Still if you need code sample a create simple dart pad and share the MRE,
