Flutter Wordpress

This library uses WordPress REST API V2 to provide a way for your application to interact with your WordPress website.

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:

1. Application Passwords
2. 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: ^0.2.0 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(
  postParams: wp.ParamsPostList(
    context: wp.WordPressContext.view,
    pageNum: 1,
    perPage: 20,
    order: wp.Order.desc,
    orderBy: wp.PostOrderBy.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,
    roles: ['subscriber'],
  ),
);

6 Fetch Comments

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

        password: password,
        username: username,
        roles: roles
      )
    ).then((p) {

      print('Failed to create user: $err');
    });
  }

8. Create Post

        content: 'Blah! blah! blah!',
        excerpt: 'Discussion about blah!',
        authorID: user.id,
        commentStatus: wp.PostCommentStatus.open,
        pingStatus: wp.PostPingStatus.closed,
        status: wp.PostPageStatus.publish,
        format: wp.PostFormat.standard,
        sticky: true,
      ),
    );

    post.then((p) {
