you have to manually add desktop support for existing apps
run: flutter create .
to add the necessary dependencies.
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.
To add desktop support to an existing Flutter project, run the following command in a terminal from the root project directory:
flutter create --platforms=windows,macos,linux .
src : https://flutter.dev/desktop#add-desktop-support-to-an-existing-flutter-app
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. :)
To add desktop support to an existing Flutter project, run the following command in a terminal from the root project directory:
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 .
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
