With Local Notifications, can I set the badge icon on iOS and Android?

With Push Notifications, I can set the badge icon on iOS and Android.

However, I want to do the same with local notifications.

For example, I made a “Todos” app and I want to show the number of due items on the todo list in the badge on the app icon on iOS. How could I do that with local notifications?

In local notifications plugin there is a smallIcon configuration option that can be used to set a global icon for local notifications.
If you want to set it per notification, the Notification types also have a smallIcon property that can be used.

That is Android only, on iOS it uses the app icon.

With Capacitor 3, I found a solution for this: the badge plugin.
