Flutter-web Webview use multiple LocalStorage management - flutter

Question

Hello i do have a problem using Webviews in my Webapp
case use :
Dashboard, which is loading multiple Webviews where each Webview with each local storage is merged with the main local storage.
first problem :
i had to use the easywebview package to solve my loading webviews issues of a webview on chrome, but i would like to use webview package.
second problem :
Whene i used my chrome app with an easywebview loading inside of it i had two localstorage running independantly i wish that i can merge all my localstorages in the dashboard one.
code sample
import 'package:easy_web_view/easy_web_view.dart';
class LoginFrameWidget extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Container(
height: double.infinity,
width: double.infinity,
child: EasyWebView(
src: "http://localhost:5111/",
isHtml: false,
isMarkdown: false,
convertToWidgets: false,
onLoaded: () {},
));
}
}
Image of the localstorages:
localstorages
Solution needed:
make one main LocalStorage
using webviews instead of easywebview (if possible)

Answer 1

after some research i ended up with a different solutions:
//setup iframe
_iframeElement.height = '500';
_iframeElement.width = '500';
//listen to iframe (window.post.message)
window.onMessage.listen((event) {
print(event.data);
//some localstorage logic
});
_iframeElement.src = 'path';
_iframeElement.style.border = 'none';
// ignore: undefined_prefixed_name
ui.platformViewRegistry.registerViewFactory(
'iframeElement',
(int viewId) => _iframeElement,
);
_iframeWidget = HtmlElementView(
key: UniqueKey(),
viewType: 'iframeElement',
);
and than i just passed the collected data on queries
if there is a better solution i would listen to that.
