ion-back-button
The back button navigates back in the app's history when clicked. It is only displayed when there is history in the navigation stack, unless defaultHref is set. The back button displays different text and icon based on the mode, but this can be customized.
Basic Usage
Custom Back Button
By default, the back button will display the text "Back" with a "chevron-back" icon on ios, and an "arrow-back-sharp" icon on md. This can be customized per back button component by setting the icon or text properties. Alternatively, it can be set globally using the backButtonIcon or backButtonText properties in the global config. See the Config docs for more information.
Default Back History
Occasionally an app may need to show the back button and navigate back when there is no history. This can be done by setting the defaultHref on the back button to a path. In order to use defaultHref, the app must contain a router with paths set.
