A Flutter plugin project to manage events (time, place and attendees) using the @‎platform.

Now for some internet optimism.

at_events_flutter

Introduction

A flutter plugin project to manage events between atsigns.

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.

Manually add the package to a project:

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

Clone it from github

Feel free to fork a copy of the source from the GitHub Repo

Initialising:

It is expected that the app will first authenticate an atsign using the Onboarding widget.

The event service needs to be initialised with a required GlobalKey

  initialiseEventService(
    navKey,
    mapKey: 'xxxx',
    apiKey: 'xxxx',
    rootDomain: 'root.atsign.org',
    streamAlternative: (__){},
    initLocation: true,
  );

As this package needs location permission, so add these for:

IOS: (ios/Runner/Info.plist)

<key>NSLocationWhenInUseUsageDescription</key>
<string>Explain the description here.</string>

Android: (android/app/src/main/AndroidManifest.xml)

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

at_events_flutter depends on at_location_flutter for the following features:

• Sending/receiving location, make sure to initialise at_location_flutter inside/outside the at_events_flutter package, if location sharing is needed.
• To render the map, pass [mapKey] to [initializeLocationService], if map is needed.
• To calculate the ETA, pass [apiKey] to [initializeLocationService], if ETA is needed.

Usage

To create a new event, using the default screen:

  CreateEvent(
    AtClientManager.getInstance(),
  ),

To use event creation/edit functions, use the [EventService()] singleton, make sure to call [EventService().init()] before using these functions:

• createEvent() - Can create and edit based on [isEventUpdate] passed to [init()]
• editEvent() - Will update the already created event
• sendEventNotification() - Will create a new event

Navigating to the map screen for an event:

EventsMapScreenData().moveToEventScreen(eventNotificationModel);

Different datatypes used in the package:

 - EventNotificationModel: Contains the details of an event and is sent to atsigns while creating an event.
 - EventKeyLocationModel - The package uses this to keep a track of all the event notifications.
