Run is one of the commands of the pub tool. Learn more about pub.

$ pub run [--mode=<mode>] [--checked] <executable> [args...]

Use this command to run a Dart script in your package, or in one of its dependencies, from the command line. If your app uses transformers, pub loads and runs the appropriate transformers, then runs the app, passing in any specified parameters.

To run an executable when you are not currently inside a package, see the pub global command.

Running a script in your package’s bin directory

This is the simplest use case.

From the root of a package that contains foo.dart in the bin directory, run the app using the following command:

$ pub run foo arg1 arg2

This command looks in your package’s bin directory for the specified script and invokes it, passing in any arguments.

Running a script in another directory in your package

To run a script inside a directory other than the top-level bin directory (but within the package), prepend the path to the name of the script. For example, to run foo.dart in the example/sub directory:

$ pub run example/sub/foo arg1 arg2

Running a script in a dependency

To run a script from the bin directory of a package that you depend on in the pubspec, specify the package name. For example, to run bar.dart in the foo package:

$ pub run foo:bar arg

You can only run scripts out of another package’s bin directory. All other directories are private.

Options

For options that apply to all pub commands, see Global options.

--checked
Optional. Specify to run in checked mode. It defaults to non-checked mode.
