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? enter image description here

Btw every thing is okay with Flutter Doctor

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.

dart pub global activate rps (or some other package)

After each update it invalids these packages.

Actually this was the solution in my case where I upgraded Flutter and running Melos was yielding this error. Thanks. ;) – Gametogenesis

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:

  1. Download dart sdk

  2. Unzip it to c:\tools\dart-sdk or any other folder (make sure you rename or delete the existing dart-sdk folder)

  3. ctrl-shift-p, type 'user settings (JSON)', open the json settings, and add:

  "dart.sdkPath": "C:\\tools\\dart-sdk",

  1. Update your system PATH environmental variable to point to the new dart-sdk and delete the reference to the old location.

  2. Restart VS Code.

Note that Instead of This "dart.sdkPath": "D:\Dart\dart-sdk\bin" work well for me. path should be included '\bin' also. It work for me
