How do I pass messages back from the html page to native ? #168
Description
I tried a couple things.
- doing a window.open
- 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?
