Based on Guance iOS Android SDK Plugin
Please refer to the official documentation click here
ft_mobile_agent_flutter currently provides native bridge support for Android and iOS only. It does not provide a Flutter Web bridge.
If your app runs on Flutter Web, use the Guance Browser RUM SDK instead. In a Flutter Web project, load the Browser RUM SDK or your bundled initialization script from web/index.html before Flutter starts. This is a Browser RUM SDK integration, not a Flutter plugin integration.
For details, see the Flutter Web notes and the Web RUM integration guide.
