iOS 26 supports a new modifier called tabViewBottomAccessory that allows you to attach a view that floats above the tab bar and is aware of whether the tab bar is expanded or collapsed via the TabViewBottomAccessoryPlacement environment variable.

I would love to have this api exposed to react-native-bottom-tabs. We could have the placement be available in context of the Tabs

<Tabs tabViewBottomAccessory={MyAccessoryView}>...</Tabs>
function MyAccessoryView() {
 const placement = useTabViewBottomAccessoryPlacement()
 return (
 <View styles={{ backgroundColor: placement === 'inline' ? 'red' : 'green' }} />
 )
}
