[macos] onTrayMenuItemClick not activated in master any more.

[ghost]

Hello,

on macos in the example when using the package from pub:
tray_manager: ^0.1.3

void onTrayMenuItemClick(MenuItem menuItem) {
    print(menuItem.toJson());
    BotToast.showText(
      text: '${menuItem.toJson()}',
    );
  }

onTrayMenuItemClick is activated when I select a menu item.

When I use tray_manager from the master

tray_manager:
  path: ../

the example does not work any more.

I use the master because of issue 4
