Cloud-based cross-platform collaborative augmented reality in flutter

Augmented Reality (AR) as a technology in the business area is utilized in new frontiers such as collaborative real-time experiences and cloud-based solutions. However, there is still a strong tendency towards game engines, which hinders widespread adoption for businesses. We present a collaborative AR framework (Flutter plugin) aimed at lowering the entry barriers and operating expenses of AR applications. A cross-platform and cloud-based solution combined with a web-based content management system (cloud) is a powerful tool for non-technical staff to take over operational tasks such as providing 3D models or moderating community annotations. To achieve cross-platform support, the AR Flutter plugin builds upon ARCore (Android) and ARKit (iOS) and unifies the two frameworks using an abstraction layer written in Dart. In this extensive description we present an in-depth summary of the concepts to realize the framework and prove its performance being on the same level as the native AR frameworks. This includes application-level metrics like CPU and RAM consumption and tracking-level qualities such as keyframes per second used by the underlying SLAM algorithm, detected feature points, and area of tracked planes. Our contribution closes a gap in today's technological landscape by providing an AR framework with the familiar development process of cross-platform apps. Building upon on a content management system (cloud) and AR can be a game changer to achieve business objectives, while being not restrained to stand-alone single-purpose apps. This will trigger a potential paradigm shift for previously complex-to-realize applications relying on AR, e.g., in production and planning. The AR Flutter plugin is fully open-source, the code can be found at: https://github.com/ CariusLars/ar_flutter_plugin.
