The language tutorials presents a simple “Hello, world” client and server, showing the FIDL language definitions and continuing with sections specific to each supported target language (e.g., C++, Dart).

Read the concepts doc to get a brief overview of what FIDL is, including some of its design goals, requirements, and workflow.

Developer Guides


The bindings reference includes references of generated code in each binding and the FIDL utility libraries available to each language.

The language reference is for everything else, like the wire format and FTPs.
