Can't load Kernel binary: Invalid kernel binary format version.
I recently upgraded Flutter to version 1.22.0, but I got some errors related to a dart package that I used, so I tried to downgrade flutter by using command flutter downgrade, but that wasn't successful. There were 10 tries, but all failed. Now I get Can't load Kernel binary: Invalid kernel binary format version. this error every time I use any Flutter command....

  • flutter pub get
  • flutter upgrade
  • flutter
  • flutter clean
  • flutter downgrade
    Every time it just shows Can't load Kernel binary: Invalid kernel binary format version.

    I tried deleting flutter_tools.stamp manually, but still nothing's happening.

    FLUTTER_ROOT is not an actual folder, just where the root of your flutter installation is

    I tried deleting flutter_tools.stamp manually from flutter/bin/cache/, but still nothing's happening.
    This happens again and again ->
    Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (7 tries left)

    Initializing Flutter. This may take a few minutes. Its just stuck on this.

    I tried completely replacing the flutter file downloaded from flutter's website, and it worked.

    @hassanasif0423 For me, this advice is enough.

    try rm FLUTTER_ROOT/bin/cache/flutter_tools.stamp

    In my case,

    which flutter
=> /Users/{UserName}/Applications/flutter/bin/flutter

rm /Users/{UserName}/Applications/flutter/bin/cache/flutter_tools.stamp

    I have the same issue too.

    I solved this issue by downloading the flutter sdk from the flutter website and replacing with the one in pc.

    I fixed it now - the issue was that I had installed flutter before and flutter took parts of the old version to initialize.
    To solve it, I had to delete the old one.
