Sure, it can be done.当然，这是可以做到的。 I would recommend you to go through the official documentation of BottomTabsNavigator and try to find out a way on your own as it will help you to solve the problems in the future.我会通过BottomTabsNavigator的官方文档向您推荐go ，并尝试自己找出方法，因为它将帮助您解决将来的问题。
Hint Your TabBar function might be returning some components ie Button or TouchableOpacity.提示您的 TabBar function 可能会返回一些组件，即 Button 或 TouchableOpacity。 Just use the onPress props of the component to open a logout alert just like you might be doing to navigate between the screens.只需使用组件的 onPress 道具来打开注销警报，就像您在屏幕之间导航一样。
