Hello,

Welcome to our Microsoft Q&A platform!

Yes, if you want to invoke native platform functionality in forms, you can use Xamarin.Forms DependencyService to achieve this function just @Alessandro Caliaro said.

The DependencyService class is a service locator that enables Xamarin.Forms applications to invoke native platform functionality from shared code.

The process for using the DependencyService to invoke native platform functionality is to:

1. Create an interface for the native platform functionality, in shared code. For more information, see Create an interface.
2. Implement the interface in the required platform projects. For more information, see Implement the interface on each platform.
3. Register the platform implementations with the DependencyService. This enables Xamarin.Forms to locate the platform implementations at runtime. For more information, see Register the platform implementations.
4. Resolve the platform implementations from shared code, and invoke them. For more information, see Resolve the platform implementations.

And there is a sample included in above document, you can check it here: https://learn.microsoft.com/en-us/samples/xamarin/xamarin-forms-samples/dependencyservice/
