Whenever I try to run a dart tool like Dart Migrate I get the following error and I am unable to run that tool. Is there a way to solve this problem or I have to reinstall Flutter?
Btw every thing is okay with Flutter Doctor
Can't load Kernel binary: Invalid SDK hash in Flutter

After a lot of effort and wasting a lot of time on this issue I have been able to solve this problem. I have installed dart-sdk separately in the past and place the path of that dart-sdk at the top (before flutter one) in environment variables PATH. So I deleted that old dart-sdk path and deleted the respective folder this solved my problem.
In VS Code, if you get "Can't Load Kernel binary: Invalid SDK Hash" in Flutter or Dart, update dart.sdkPath setting
If you get this in VS Code, in addition to re-downloading the dart-sdk, make sure the "dart.sdkPath" setting in user/workspace settings is pointing to the new SDK. In my case, even though I had it in my path as in Junaid's answer, VS Code was still looking to the old dart-sdk folder and giving me the kernel hash error. I updated the dart.sdkPath to the correct path and restarted VS Code:
For example, in Windows:
Download dart sdk
Unzip it to c:\tools\dart-sdk or any other folder (make sure you rename or delete the existing dart-sdk folder)
ctrl-shift-p, type 'user settings (JSON)', open the json settings, and add:
"dart.sdkPath": "C:\\tools\\dart-sdk",
Update your system PATH environmental variable to point to the new dart-sdk and delete the reference to the old location.
Restart VS Code.
