Lemmy Dart API Client

A Lemmy API Client built with Dart. Continuation of the original Lemmy Dart API and Liftoff Dart API.

Information

Updates are done at a best-effort basis to ensure compatibility with the current major version of Lemmy. Due to the unstable nature of Lemmy API, there will be limited support for the last major version.

Notice: While efforts are made to keep as much parity as possible with the Lemmy API, it is not guaranteed. If a particular endpoint or feature is missing, feel free to create a feature request or a pull request implementing that endpoint.

Usage

import 'package:lemmy_api_client/v3.dart';

Future<void> main() async {
  // Initialize the Lemmy API Client with the given instance URI
  const lemmy = LemmyApiV3('lemmy.ml');

  // Fetch posts
  final response = await lemmy.run(const GetPosts());

  print(response);
}

Conventions

When implementing a new endpoint, try to follow the existing conventions. A basic summary of these conventions are mentioned below.

API Methods and Naming

Any high-level API methods should be placed under /api directory matching the endpoint. For example, GET /community should be placed under api/community/community.dart file.

• Always attempt to match the naming of the API or model with the official API client. This helps with parity checking and general organization.

Deprecating Fields

When a field or attribute is being deprecated in the upcoming version of Lemmy, mark it as such by annotating the field with @deprecated and making the field optional.

This example shows deprecation for the community field. Whenever possible, add an additional comment on which API version deprecates the field

const factory CommunityView({
  required Community community,
  required SubscribedType subscribed,
  required bool blocked,
  required CommunityAggregates counts,
}) = _CommunityView;

const factory CommunityView({
  @deprecated Community? community, // v0.18.0 (required) [deprecated in v0.43.0]
  required SubscribedType subscribed,
  required bool blocked,
  required CommunityAggregates counts,
}) = _CommunityView;

Adding Fields

When a field or attribute is introduced in an upcoming version of Lemmy, keep that attribute optional regardless of what the Lemmy API version denotes, and denote whether the field is optional/required. This is to ensure compatibility with the current and upcoming version of Lemmy. Furthermore, add a comment to denote which version introduces that field.

This example shows addition for the follow field:

const factory CommunityView({
  required Community community,
  required SubscribedType subscribed,
  required bool blocked,
  required CommunityAggregates counts,
}) = _CommunityView;

const factory CommunityView({
  required Community community,
  required SubscribedType subscribed,
  required bool blocked,
  required CommunityAggregates counts,
  bool? follow, // v0.64.0 (required)
}) = _CommunityView;
