void main() async {
  // Must add this line.
  WidgetsFlutterBinding.ensureInitialized();
  // For hot reload, `unregisterAll()` needs to be called.

  scope: HotKeyScope.inapp, // Set as inapp-wide hotkey.
);
await hotKeyManager.register(
  _hotKey,
  keyDownHandler: (hotKey) {
    print('onKeyDown+${hotKey.toJson()}');
  },
