Use JS library in Flutter

Question

I am trying to use Ether JS in my Flutter application. I know that it is not directly supported and even the existing implementations are not really well documented.

Answer 1

    Future loadJS(String name) async {
  var givenJS = rootBundle.loadString('assets/$name.js');
  return givenJS.then((String js) {
    flutterWebViewPlugin.onStateChanged.listen((viewState) async {
      if (viewState.type == WebViewState.finishLoad) {
        flutterWebViewPlugin.evalJavascript(js);
      }
    });
  });
}
