Riverpod — Code generation and hooks

Code generation

Code generation is optional in Riverpod. It changes the syntax for defining providers: you write an annotated function or class and the generator produces the provider. Use it if you already use code generation (e.g. Freezed, json_serializable); otherwise the extra build step may not be worth it. See riverpod-getting-started for setup (build_runner, riverpod_generator).

Benefits

• Clearer syntax: no manual provider type (Provider vs FutureProvider etc.); Riverpod infers it.
• Parameters: any parameters (named, optional, defaults) instead of a single family parameter.
• Stateful hot-reload for Riverpod code.
• Better debugging via generated metadata.
