https://reactnavigation.org/docs/native-bottom-tab-navigator#tabbaricon If you look at the content of the link above, it says that the focused property of the tabBarIcon function is not available in Android. like this, "This is only supported on iOS. On Android, the icon specified for inactive state will be used for both active and inactive states." However, it appears to be in the Android design guide. Could you add support for this feature? If feature development is not possible, Could you tell me why? Android Material Design https://m3.material.io/components/navigation-bar/overview Thank you for your hard work.
