Flutter API References

We use _webViewController to communicate with the SDK. If you need any help to understand how we get _webViewController or to check how to setup InAppWebView and to initialize properly check the Setup Page.

Webview Method

All communication is achieved by sending post messages using the _webViewController

_webViewController?.evaluateJavascript(source: """
    window.parent.postMessage(payload, '*');
""");

We just send different payloads for different functionalities.

Payloads

To get started, we send the type asinitialize type and payload with the desired settings. This adds the GlamAR SDK into the target container and configures it with the provided API key and optional configuration we sent through the payload.

const payload = {
  type: "initialize",
  payload: {
    apiKey: "YOUR_ACCESS_KEY",
    platform: "flutter",
  },
};

Initialization Payload

apiKey	string	Your Access Key
platform	string	Platform you're targeting (e.g. web)

Following are all the configuration options that can passed under theoptions object.
Subcategories defined in overview section can be passed in the category parameter.
