Extension of the toast/snack bar for scheduling (such as Plugin.LocalNotification)

[true-perfect-code]

I refer to the discussion #2326 (reply in thread)

It would be great if Toast/Snackbar could be extended so that a toast message can be scheduled for the future even if the application is closed.
It is important that the app is automatically reopened when the Toast/Snackbar message is clicked and that you can also pass an ID (which you set when creating the Toast/Snackbar message). This ID would then be used to display the correct data record from a table in the open app (can be an appointment from the calendar, for example).

The Plugin.LocalNotification is located here:
