Remove is one of the commands of the pub tool.
$ dart pub remove <package> [options]
This command removes the specified package from the pubspec as a dependency.
For example, the following command is equivalent to
editing pubspec.yaml (removing http from dependencies or dev_dependencies)
and then calling dart pub get:
$ dart pub remove http

-n, --dry-run
