I tried a couple things.

  1. doing a window.open
  2. hooking into the script message mechanism by using a userContentController and WKScriptMessageHandler

nothing seems to work.

even an alert does not fire.
Here is my webview plugin

var str = "<html><body><h1>Add text below</h1><input type='text' name='email' id='email'/><button onclick='window.open(\"http:\\www.cnn.com\"); '>Click me</button></body></html>";
        var url = new Uri.dataFromString(str, mimeType: 'text/html').toString();
        
        flutterWebviewPlugin.launch(url,
                  rect: new Rect.fromLTWH(
                      00.0, 100.0, 300.0, 440.0));

the navigation to cnn.com does not happen on button click.
I also tried to just do an alert but did not work.

var str = "<html><body><h1>Add text below</h1><input type='text' name='email' id='email'/><button onclick='alert(\"test message\"); '>Click me</button></body></html>";

what seems to be the issue? any ideas?

first of all, set enableJavascript to true when launching webiew. if you want to push messages to native from website, you need to use some javascript redirection for urls and listen to them in native.
