Requirements

For authentication and usage of administrator level REST APIs, you need to use either of the two popular authentication plugins in your WordPress site:

Application Passwords
JWT Authentication for WP REST API (recommended)

Getting Started

1. Import library

First:

Find your pubspec.yaml in the root of your project and add flutter_wordpress: ^0.1.4 under dependencies:

Second:

import 'package:flutter_wordpress/flutter_wordpress.dart' as wp;

2. Instantiate WordPress class

wp.WordPress wordPress;

// adminName and adminKey is needed only for admin level APIs
wordPress = wp.WordPress(
  baseUrl: 'http://localhost',
  authenticator: wp.WordPressAuthenticator.JWT,
  adminName: '', 
  adminKey: '',
);

3. Authenticate User

Future<wp.User> response = wordPress.authenticateUser(
  username: 'ChiefEditor',
  password: 'chiefeditor@123',
);

response.then((user) {
  createPost(user);
}).catchError((err) {
  print('Failed to fetch user: $err');
});

4. Fetch Posts

Future<List<wp.Post>> posts = wordPress.fetchPosts(
  params: wp.ParamsPostList(
    context: wp.WordPressContext.view,
    pageNum: 1,
    perPage: 20,
    order: wp.Order.desc,
    orderBy: wp.PostsOrderBy.date,
  ),
  fetchAuthor: true,
  fetchFeaturedMedia: true,
  fetchComments: true,
);

5. Fetch Users

Future<List<wp.User>> users = wordPress.fetchUsers(
  params: wp.ParamsUserList(
    context: wp.WordPressContext.view,
    pageNum: 1,
    perPage: 30,
    order: wp.Order.asc,
    orderBy: wp.UsersOrderBy.name,
    role: wp.UserRole.subscriber,
  ),
);

6. Fetch Comments

Future<List<wp.Comment>> comments = wordPress.fetchComments(
  params: wp.ParamsCommentList(
    context: wp.WordPressContext.view,
    pageNum: 1,
    perPage: 30,
    includePostIDs: [1],
  ),
);

7. Create Post

void createPost(wp.User user) {
  final post = wordPress.createPost(
    post: new wp.Post(
      title: 'First post as a Chief Editor',
      content: 'Blah! blah! blah!',
      excerpt: 'Discussion about blah!',
      author: user.id,
      commentStatus: wp.PostCommentStatus.open,
      pingStatus: wp.PostPingStatus.closed,
      status: wp.PostPageStatus.publish,
      format: wp.PostFormat.standard,
      sticky: true,
    ),
  );

  post.then((p) {
    print('Post created successfully with ID: ${p.id}');
    postComment(user, p);
  }).catchError((err) {
    print('Failed to create post: $err');
  });
}

8. Post Comment

void postComment(wp.User user, wp.Post post) {
  final comment = wordPress.createComment(
    comment: new wp.Comment(
      author: user.id,
      post: post.id,
      content: "First!",
      parent: 0,
    ),
  );

  comment.then((c) {
    print('Comment successfully posted with ID: ${c.id}');
  }).catchError((err) {
    print('Failed to comment: $err');
  });
}

Future Work

Implementing OAuth 2.0 authentication.

This is a sample WordPress App built with flutter_wordpress API (https://pub.dartlang.org/packages/flutter_wordpress)
You can use this API to connect to any existing WordPress Website. This library uses WordPress REST API V2 to provide a way for your application to interact with your WordPress website.

Basic login, displaying posts and comments have been implemented in this example flutter app.
