just for who get error after running this command, need to include --org parameter if you changed the package name.
Do not miss the dot in the end of the expression

You might have missed step from linux desktop support. It is because you're trying to run project which is initial build from different platform (eg. mac/windows). This is according to official documentation. flutter_add_linux

Another solution is create new app by flutter create repo_name on linux. Then copy linux folder into existing repo. This will fix your problem.

Here we add full desktop support

flutter create --platforms=windows,macos,linux .

Only need Windows

flutter create --platforms=windows .

Only need Linux

flutter create --platforms=linux .

Tip:

To create a new application that includes desktop support (in addition to mobile and web support), run the following commands, substituting myapp with the name of your project:

flutter create myapp
cd myapp

For more Information : flutter.dev/desktop

Use these commands

$ flutter channel dev

$ flutter upgrade

$ flutter config --enable-linux-desktop

After running these commands start a new Flutter project and you should be good to go. :)
