How to use RemoteAPI in the Camerakit Flutter Sample

Hello @Deniz Çetin, thank you for the question about Remote APIs and Flutter. The Flutter Sample does not include Remote API support at the moment. If you'd like to develop this functionality, you might, first, import the Cat Fact example from our iOS Sample App to the Flutter App.

There are three steps to implementing Remote API in the Flutter app:

1. Import CatFactLensRemoteApi.swift to your Flutter app project

2. Pass the RemoteApiServiceProvider() to CameraKit's data provider:

    /// Configures the data provider for lenses. Subclasses may override this to customize their data provider.
    /// - Returns: a configured data provider.
    open func configureDataProvider() -> DataProviderComponent {
        // By default, CameraKit will handle data providers (such as device motion),
        // but if you want to handle specific data provider(s), pass them in here, example:
        DataProviderComponent(
            deviceMotion: nil, userData: UserDataProvider(), lensHint: nil, location: nil,
            mediaPicker: lensMediaProvider
        )
    }

3. The Cat Fact Lens is one of the Camera Kit Mobile Sample Lenses, which can be found in the Camera Kit portal. Load this Lens group in your app.

These steps should help avoid some of the errors you encountered. Once you have this working, you can work with your own Remote API Lens and also establish communication between the Lens and Flutter container.
