Answer 1

While run Desktop App Error

solution:

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 .

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
