I develop POS system using Flutter Web.
In POS system we need to have second screen to display the ordered product.

My question is:
1.Is there any way to share state in flutter web?
2.If can’t ,Is there any solution with my case ?

Thanks.

I do some research , have a few option in my case :
1.Web socket
2.Storage
…

But i don’t know it’s a good practice or not.
