Flutter launch error

[abhilashraju]

I was following steps here https://flutter.dev/docs/get-started/install/linux#update-your-path When I launch the flutter demo, I am getting the following error. My clang and cmake are latest versions

Does this seem right to you?

Nope . that is why i am confused. I have the latest CMake installed. But still flutter doctor reported the above issue. wanted to know what might have gone wrong. see the output of apt install cmake below

@abhilashraju did you install Flutter using snap?

Regardless, I wanna say:

• This issue does not belong here. This repository only contains experimental plugins now & not actual desktop embedding, that is now part of Flutter engine itself.
• Give up using snap.

[abhilashraju]

I am not using snap I cloned the repo.

I am not using snap I cloned the repo.

Doesn't seem like it. Possibly you are still invoking old snap version. Confirm with whereis flutter.

@alexmercerind It does not appear that you know what a snap installation looks like in doctor; it is not helpful to argue with people about how they installed if you don't know how to tell from the provided output (doubly so when you already know that it is off topic here.)
