Lichess API interface for Dart

This is a library that defines signatures (interface) to interacting with Lichess API. This also defines all required data models. It is written in pure Dart using code-generation.

You are very unlikely to be searching for this library though, this was created to remove the HTTP library dependency from the API interface, it acts like a "platform interface" package.

Notice: This is not an official Lichess project. It is maintained by volunteers.

Installation

dependencies:
  lichess_client: ^<latest-version>

Import:

import 'package:lichess_client/lichess_client.dart';

Custom client

class MyCustomLichessClient implements LichessClient {
  // TODO: Implement/override methods.
}

LichessClient is the abstract class that defines all signatures, so you can always extend or implement it.

Now you can do your own implementation and re-use the data models.

This can also be used to mock the LichessClient class.

Contributing

Dependencies other than code generation aren't allowed in this package, contributions are allowed only to change, add or remove signatures that corresponds to the Lichess API, if you wanna implement something, create a new package that depends on this package instead. We also offer a package that implements this interface using Dio as HTTP client.

Code generation

This package uses code generation to handle data models:

# Get deps.
dart pub get

# Generate code, switch 'watch' for 'build' if you don't wanna watch for file changes.
dart run build_runner watch --delete-conflicting-outputs

It's done, add any model or signature and send PR.
