          String javascriptString;

          javascriptString =
              '''Tawk_API = Tawk_API || {};Tawk_API.onLoad = function() {Tawk_API.setAttributes($json);''';

          await controller.runJavascript(javascriptString);

          setState(() {});

试试这个:

controller.evaluateJavascript(source: yourCode).then((result) {
debugPrint(result);
});
