[freeboub]

Description

When using react-native-screens on android, the prop transitionDuration is not taken into account.
reproduced with fabric & react native 0.77.
It work fine on ios.

Sample video where I put 10sec in transitionDuration

Steps to reproduce

Here is the sample code to reproduce the issue:

    <ScreenStack style={StyleSheet.absoluteFill}>
      <Screen
        key="parent"
        activityState={2}
        style={StyleSheet.absoluteFill}>
        <Pressable
            style={styles.pressable}
            onPress={() => {
              setChildDisplayed(true);
            }}/>
      </Screen>
      {childDisplayed ? (
        <Screen
          key="child"
          activityState={2}
          transitionDuration={10000}
          isNativeStack
          stackAnimation={'slide_from_bottom'}
          style={StyleSheet.absoluteFill}>
            <View style={styles.square}/>
        </Screen>) :
        <></> }
    </ScreenStack>

Hey @freeboub, you're right it is not supported on Android. See the types:

react-native-screens/src/types.tsx

Lines 472 to 478 in 32c3a19

	/**
	* Changes the duration (in milliseconds) of `slide_from_bottom`, `fade_from_bottom`, `fade` and `simple_push` transitions on iOS. Defaults to `500`.
	* The duration of `default` and `flip` transitions isn't customizable.
	*
	* @platform ios
	*/
	transitionDuration?: number;

This is due to how animations are currently implemented on Android. Refactor of these is on my task board, however can't give any estimates.

I'll close the ticket, since it is not a bug.

Ok, thank you for the quick feedback on this point !
