AtomicResult Error In My Flutter App after Windows Update - flutter

Question

Just updated Windows and my app won't compile. A file called AtomicRestult seems to be the problem, I have never heard of this file.
The error message that appears is below:

I have no idea what this file does and not sure what could possibly be wrong. I suspect that it could be the code but can't be too sure.
The below is a response to a suggestion.
I updated amplify core and I get the error message below:
Because no versions of amplify_auth_cognito match >0.2.10 <0.3.0 and amplify_auth_cognito >=0.2.0 <0.2.1 depends on amplify_core 0.2.0, amplify_auth_cognito >=0.2.0 <0.2.1-∞ or >0.2.10 <0.3.0 requires amplify_core 0.2.0.

So, because newday depends on both amplify_auth_cognito ^0.2.0 and amplify_core ^0.6.6, version solving failed.

Answer 1

The error is being generated from a package you are using. The version of the package is quite old and you need to update it.
Update amplify_core package in pubspec.yaml file
amplify_core: ^0.6.6
