Integrating complex, interactive components into enterprise web applications is a frequent challenge. To ensure code consistency and design parity, we successfully refactored a mobile Flutter package into a platform-agnostic solution compatible with the web.

This talk demonstrates how we leveraged Flutter’s Multi-View Web API to embed multiple, independent Flutter components into a host web application, allowing them to function seamlessly alongside native content. We will explore the architecture required for production-scale integration, focusing on managing component lifecycles and using Dart’s JS Interop for robust, type-safe, two-way communication.
