A Flutter plugin project to provide group functionality with contacts using atPlatform.

pub package gitHub license

Overview #

The at_contacts_group_flutter package is for Flutter developers who want to add the group functionality to their apps on atPlatform.

This open source package is written in Dart, supports Flutter and follows the atPlatform's decentralized, edge computing model with the following features:

  • Cryptographic control of data access through personal data stores
  • No application backend needed
  • End to end encryption where only the data owner has the keys
  • Private and surveillance free connectivity
  • Create and manage groups

We call giving people control of access to their data “flipping the internet” and you can learn more about how it works by reading this overview.

Get started #

There are three options to get started using this package.

1. Quick start - generate a skeleton app with at_app #

This package includes a working sample application in the Example directory that you can use to create a personalized copy using at_app create in four commands.

$ flutter pub global activate at_app 
$ at_app create --sample=<package ID> <app name> 
$ cd <app name>
$ flutter run


  1. You only need to run flutter pub global activate once
  2. Use at_app.bat for Windows

2. Clone it from GitHub #

Feel free to fork a copy the source from the GitHub repo. The example code contained there is the same as the template that is used by at_app above.

$ git clone

3. Manually add the package to a project #

Instructions on how to manually add this package to you project can be found on here.

How it works #

This package utilises the at_contact dart package and provides the CRUD feature on group of contacts.

Setup #


The groups service along with the contacts service needs to be initialised with the root server.

initializeContactsService(rootDomain: AtEnv.rootDomain);
initializeGroupService(rootDomain: AtEnv.rootDomain);

Usage #

Navigating to the groups list is done simply by using:

	builder: (BuildContext context) => GroupList(),
