Bridging Worlds: Achieving Two-Way Communication Between Flutter and WebView

Introduction

Flutter, the robust UI framework developed by Google, has revolutionised the way we build cross-platform mobile applications. One of its exceptional features is the integration of WebViews, allowing developers to embed web content seamlessly within their Flutter apps. While this opens up exciting possibilities, what truly sets your app apart is when you enable two-way communication between your app and the loaded web page.
