Banuba ARCloud plugin

AR Cloud is a client-server solution that helps to save space in your application. This is a product used to store AR filters i.e. masks on a server-side instead of the SDK code. After being selected by the user for the first time, the filter is going to be downloaded from the server and then saved on the phone's memory.

Usage

BanubaARCloudPlugin is the main class responsible for all interactions with AR Cloud.

First, create new instance.

final plugin = BanubaARCloudPlugin();

Listen to any effects changes using getEffectsStream() method. List of effects contains local(stored in the local database) and remote(stored on AR Cloud) effects. The callback is called when

• effects are loaded from local database
• effects are loaded from AR Cloud
• effect is downloaded

final effectsStreamSubscription = plugin.getEffectsStream().listen(
_onEffectsLoaded,
onError: (e) => ...,
);

Set your AR Cloud url. Normally this url is provided by Banuba representatives.

 final arCloudUrl = '';
 plugin.init(arCloudUrl: arCloudUrl);

Load effects from AR Cloud. New list of effects will be pushed when effects are loaded from AR Cloud successfully.

Future<void> _loadEffects() async {
  await plugin.loadEffects();
}

Download effect. New list of effects will be pushed to the stream when the effect is downloaded.

try {
await plugin.downloadEffect(effect.name);
} on Exception catch (e) {
// handle exception
}

Dispose plugin when you complete interaction with AR Cloud.

 @override
  void dispose() {
    _effectsStreamSubscription.cancel();
    _plugin.dispose();
    super.dispose();
  }
