When i try to run app in debug mode the following error occurs. flutter
This error comes while I try to make body of scaffold scrollable and I have add flutter_html package in my pubspecs.yaml at that time.
I think the problem is from the new inserted package but not confirmed. Can you please help me in solving this problem?

I guess the versions you are using:
- Flutter SDK v3.x
- flutter_html v2.x
I verified the problem you said by this version, please upgrade the flutter_html version to v3.x.
Although the version called Pre-release, it can solve this problem you said.
