What is package in Dart?

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

plugin= some functionality of tool. Package= something which allows us to develop new thing .

At a minimum, a Dart package is a directory containing a pubspec file . The pubspec contains some metadata about the package. Additionally, a package can contain dependencies (listed in the pubspec), Dart libraries, apps, resources, tests, images, and examples.
