Target kernel_snapshot failed: Exception: Errors during snapshot creation: null build failed

I have updated to the latest flutter update. When I want to start the project, it returns an error. The project depends on several repositories and I don't know if that is why. I have tried multiple solutions but they do not solve the error. Hope someone can help me. thanks.

Compiler message:

i found this issue issue TL:DR here is a summary

It looks like your local engine build flutter/engine and framework + tool flutter/flutter are out of sync: You're using an engine from when after SemanticsFlag.isLink was added, but a framework/tool from before it rolled into the framework.

You need to ensure that you're using compatible engines and frameworks. In this case, you need to either update flutter/flutter to a newer version or roll back flutter/engine to an older version.

import 'package:food_ecommerce/pages/flutter/packages/flutter/lib/cupertino.dart';
import 'package:food_ecommerce/pages/flutter/packages/flutter/lib/widgets.dart';

Delete such headers in my case I delete these two headers and my program runs.
