This tutorial shows you how to implement a FIDL protocol
(fuchsia.examples.Echo
) and run it on Fuchsia. This protocol has one method
of each kind: a fire and forget method, a two-way method, and an event:

For more on FIDL methods and messaging models, refer to the [FIDL concepts][concepts] page.
This document covers how to complete the following tasks:
- Implement a FIDL protocol.
- Build and run a package on Fuchsia.
- Serve a FIDL protocol.
The tutorial starts by creating a component that is served to a Fuchsia device and run. Then, it gradually adds functionality to get the server up and running.
