In my flutter app, I have a
ConnectivityStatus widget which displays the current connection status of the app to my raspberry pi. In the
initState of my widget, I subscribe to a timer to check the connection every 5 seconds and update the state accordingly, then unsubscribe upon disposal.
The issue is, when multiple screens use the
ConnectivityStatus widget, such as in a stack navigator setup, I now have two concurrent subscriptions as neither instance has disposed. This causes many redundant, unneeded requests to occur.
