This is the unofficial Flutter SDK for the Farcaster protocol. It contains two useful API clients (one for Farcaster Hubs using Hubble and one for Warpcast) to be used in your Flutter app.

๐Ÿ“š Getting started

Available platforms

This library is available for both Flutter and Dart projects. These are the platforms where you can use this sdk:

  • x Android
  • x iOS
  • x Windows
  • x Linux
  • x MacOS

This package does not work on the web.

Add dependency

You can use this command to add farcaster_sdk to your Flutter app:

flutter pub add farcaster_sdk

It can also be used in dart projects by running a similar command:

dart pub add farcaster_sdk

Or you can manually add farcaster_sdk into the dependencies section in your pubspec.yaml file:


The current latest version is 0.0.4.

โ“ Usage

The goal of this library is to be really simple to use in your Flutter apps.

Depending on which API client you want to use, you just need to initialize it. Both clients are singletons by design to be able to be reused inside your app.

Hubble (Farcaster Hubs)

import 'package:farcaster_sdk/farcaster_sdk.dart';

final farcasterHubbleClient = FarcasterHubbleClient();

void main() async {
    await farcasterHubbleClient.init(
        // optional credentials (insecure by default)


import 'package:farcaster_sdk/farcaster_sdk.dart';

final farcasterWarpcastClient = FarcasterWarpcastClient();

void main() async {
    await farcasterWarpcastClient.init(
        // Your API url, default is "https://api.warpcast.com", you can leave this blank.
