Modal's onDismiss callback is wrongly implemented in 0.61.0-rc.3

[wddwycc]

Issue:

With This commit, onDismiss on Modal will never be called when dismissed, code below as an example.

const App = () => {
 const [visible, setVisible] = useState(true)
 const onClosePress = useCallback(() => setVisible(false), [])
 const onDismiss = useCallback(() => { console.log('dismiss') }, [])
 return (
 <View>
 <TouchableOpacity onPress={onClosePress}>
 <Text>Close</Text>
 </TouchableOpacity>
 <Modal visible={visible} onDismiss={onDismiss} />
 </View>
 )
}

This is not the intended behavior of this callback according to the document

The commit bd2b7d6 is a disaster. It actually introduced the problem which it claims to solve in its summary. Would be great to see it reverted asap.

# Problem:
`onDismiss` prop isn't being called once the modal is dismissed, this diff fixes it.

Fix for this issue is on the way, I'll try to get it cherry-picked in the next RC for 0.61 as well. #26490
Thanks for reporting this!

This issue has been resolved with a5353c0

This still seems to be broken as of 0.61.5

The same issue confirmed in 0.62 stable release. It seems the Fix is not included in the new release.

I was sort of hoping, that the onDismiss callback would also fire, if I swipe it away on iOS. It doenst do that for me on 0.62.1
