Arri Dart Codegen

Setup

1) Add the generator to your arri config

// arri.config.ts
import { defineConfig, generators } from "arri";

export default defineConfig({
    generators: [
        generators.dartClient({
            clientName: "MyClient",
            outputFile: "./client/src/my_client.g.dart",
        }),
    ],
});

Options:

2) Install the Dart client library

The generated code relies on the Dart arri_client library. So be sure to install it wherever the generated code is being used. The version number should match your Arri CLI version. (run arri version to check).

dart pub add arri_client

Using the Generated Code

Initialize the client

// this will match whatever you put in the arri config
import "./my_client.g.dart";

main() async {
    final client = MyClient(
        baseUrl: "https://example.com",
        headers: () async {
            return {
                "Authorization": "<some-token>",
            };
        },
    );
    await client.myProcedure();
}

The root client will be a class containing all of the services and procedures in a single class. If you only need a particular service, you can initialize just that service.

final service = MyClientUsersService(
    baseUrl: "https://example.com",
    headers: () async {
        return {
            "Authorization": "<some-token>",
        };
    },
);

Using Arri Models

All generated models will be immutable. They will have access to the following features:

Methods:

• Map<String, dynamic> toJson()
• String toJsonString()
• String toUrlQueryParams()
• copyWith()

Factory Methods:

• empty()
• fromJson(Map<String, dynamic> input)
• fromJsonString(String input)

Overrides:

• == operator (allows for deep equality checking)
• hashMap (allows for deep equality checking)
• toString (will print out all properties and values instead of Instance of X)

This library was generated with Nx.
