Description

This could help support webapps, and enable cross communication between our flutter app and the webview as is possible with the native webview. Is this achievable?

Research direction
Review the plugin's native code for Android (FlutterWebviewPlugin.java) and iOS to understand current WebView implementation. Investigate how to add a JavaScript interface using addJavascriptInterface on Android and WKUserContentController on iOS. Check if there are existing discussions or PRs addressing this feature. Consider creating a proposal with expected API before implementation.
