This is because of recent flutter updates. All flutter SDKs >= V2.10.3 have this issue. There's no proper solution for this error yet. 

Temporary Solution:
You can simply downgrade your flutter sdk to V2.10.2 or lower to get rid of this issue.

Note:
After downgrading make sure you also change the dart version in pubspec.yaml of your flutter project acording to the flutter SDK.
