ShortcutRegistrar class

A widget that holds a ShortcutRegistry which allows descendants to add, remove, or replace shortcuts.

This widget holds a ShortcutRegistry so that its descendants can find it with ShortcutRegistry.of or ShortcutRegistry.maybeOf.

The registered shortcuts are valid whenever a widget below this one in the hierarchy has focus.

To add shortcuts to the registry, call ShortcutRegistry.of or ShortcutRegistry.maybeOf to get the ShortcutRegistry, and then add them using ShortcutRegistry.addAll, which will return a ShortcutRegistryEntry which must be disposed by calling ShortcutRegistryEntry.dispose when the shortcuts are no longer needed.

To replace or update the shortcuts in the registry, call ShortcutRegistryEntry.replaceAll.

To remove previously added shortcuts from the registry, call ShortcutRegistryEntry.dispose on the entry returned by ShortcutRegistry.addAll.
