Where is the Pubspec yaml?

yaml file, often referred to as the pubspec. A basic pubspec is generated when you create a new Flutter project. It’s located at the top of the project tree and contains metadata about the project that the Dart and Flutter tooling needs to know.

Every pub package needs some metadata so it can specify its dependencies. Pub packages that are shared with others also need to provide some other information so users can discover them. All of this metadata goes in the package’s pubspec: a file named pubspec. yaml that’s written in the YAML language .

By default, the system package cache is located in the . pub-cache subdirectory of your home directory (on macOS and Linux), or in %LOCALAPPDATA%\Pub\Cache (on Windows; the location might vary depending on the Windows version).
