Introduction #

A Flutter extension to the at_client library which adds support for mobile, desktop and IoT devices.

SDK that provides the essential methods for building an app using The @protocol. You may also want to look at at_client.

at_client_mobile package is written in Dart, supports Flutter and follows the @platform'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

We call giving people control of access to their data "flipping the internet".

Get Started #

Initially to get a basic overview of the SDK, you must read the atsign docs.

To use this package you must be having a basic setup, Follow here to get started.

Check how to use this package in the at_client_mobile installation tab.

Usage #

  • Get KeyChainManager instance to manage your keys while switching between atsigns.
import 'package:at_client_mobile/at_client_mobile.dart';

static final KeyChainManager _keyChainManager = KeyChainManager.getInstance();

/// Fetch atsign from the keychain manager
String atSign = await _keyChainManager.getAtSign();
  • Delete atsign from the keychain manager
await _keyChainManager.deleteAtSignFromKeychain(atsign);
  • Fetch List of atsigns from the keychain manager.
List<String>? atSignsList = await _keyChainManager.getAtSignListFromKeychain();
  • Make an atsign primary in device storage.
AtClientManager.getInstance().setCurrentAtSign(atsign, AppConstants.appNamespace, AtClientPreference());

bool isAtsignSetPrimary = await _keyChainManager.makeAtSignPrimary(atsign);

print(isAtsignSetPrimary); // Prints true if set primary.
  • Get atsign status from device storage.
Map<String, bool?> atSignsWithState = await _keyChainManager.getAtsignsWithStatus();

print(atSignsWithState); // Prints a map of atsigns with their status.

/// Output:
/// {
///   "@atsign1": true, // @atsign1 is set as primary
///   "@atsign2": false,
///   "@atsign3": false
/// }
  • Reset atsigns from device storage.
for (String atsign in atSignsList) {
    await _keyChainManager.resetAtSignFromKeychain(atsign);
}
  • Get AtClientService instance to manage your atsigns.

OnboardingWidgetService is used to onboard your atsigns. Ckeck out the at_onboarding_flutter for more details.

Map<String?, AtClientService> atClientServiceMap = {};

/// Onboarding widget
OnboardingWidgetService().onboarding(
    fistTimeAuthNextScreen: FirstTimeScreen(),
    nextScreen: null,
    atsign: myAtSign,
    onboard: (value, atsign) async {
        atClientServiceMap = value;
    //... YOUR CODE ...//
    },
    onError: (error) {
        print(error);
    },
);
  • Remove an AtSign from the AtClientService.
await _keyChainManager.deleteAtSignFromKeychain(atsign);
atClientServiceMap.remove(atsign);
  • Check if an atSign is onboarded.
bool isOnboarded = atClientServiceMap.containsKey(atsign);
print(isOnboarded); // Prints true if onboarded.
  • Format of the .env file
NAMESPACE = "at_client_demo"
ROOT_DOMAIN = "root.atsign.org"
  • Adding the .env file to pubspec.yaml
flutter:
  assets: 
    - .env
