# Examples

The examples in `package:hooks` show how to use `package:hooks` and
`package:code_assets` in build hooks to bundle native code with Dart and Flutter
applications.

The following examples showcase individual features of of `package:hooks`:

* [build/](build/) contains examples on how to use `hook/build.dart` to build
  and bundle code assets, such as C libraries, into Dart applications.
* [link/](link/) contains examples on how to treeshake unused assets from a Dart
  application using the `hook/link.dart` script.
