UserScriptWebViewWrapperDelegate class

An implementation of WebViewWrapperDelegate that allows to inject required Contentsquare script in the WebView through user script.

This injection must be done through the UserScript like in the initialUserScripts parameter of InAppWebView of the package flutter_inappwebview.

Usage:

// Using the `InAppWebView` of `flutter_inappwebview`

ContentsquareWebViewWrapper(
  delegate: UserScriptWebViewWrapperDelegate(
    builder: (BuildContext context, String userScript) {
      return InAppWebView(
        initialOptions: InAppWebViewGroupOptions(
          crossPlatform: InAppWebViewOptions(
            // 1. Ensure JavaScript is enabled
            javaScriptEnabled: true,
          ),
        ),
        initialUrlRequest: URLRequest(
          url: Uri.parse(url),
        ),
        initialUserScripts: UnmodifiableListView([
          UserScript(
            // 2.a Initialized the delegate properly
            // by setting the userScript as source
            source: userScript,
            // 2.b Initialized the delegate properly
            // by setting the injectionTime as AT_DOCUMENT_START
            injectionTime: UserScriptInjectionTime.AT_DOCUMENT_START,
          ),
        ]),
      );
    },
  ),
)
