Flutter Can't load Kernel binary: Invalid kernel binary format version.

This error typically occurs when there is a version mismatch between the Flutter SDK and the Dart SDK. To resolve this issue, you can try the following steps:

Make sure you have the latest version of Flutter and Dart SDK installed. You can update them by running the following commands in your terminal:
```
flutter upgrade
flutter doctor
```
These commands will upgrade Flutter and also check for any potential issues.
If you have recently upgraded Flutter SDK, you may need to delete the flutter_sdk/bin/cache directory and let Flutter re-download the necessary files. In your terminal, run:
```
rm -rf <path_to_flutter_sdk>/bin/cache
flutter doctor
```
Replace <path_to_flutter_sdk> with the actual path to your Flutter SDK.
If the above steps don't work, you can try a complete reinstall of Flutter. This involves removing the SDK completely and then installing the latest version.
- Delete the Flutter SDK directory.
- Download the latest Flutter SDK from the official website and extract it to a desired location.
- Set the PATH environment variable to include the Flutter SDK's bin directory.
- Run flutter doctor to verify the installation.

If none of these solutions work, there might be some other underlying issue with your Flutter installation. You can try seeking help from the Flutter community by posting your issue to the Flutter GitHub repository or discussing it on the Flutter Dev Google Group.
