Shared Element Transition not Working With Latest React Native

[aymather]

Description

I'm trying to master the concept of using shared element transitions. I've set up a very basic example which animates a view with some standard properties to animate. Then I added the layer of custom animations. I am not doing anything fancy in the custom animation, I essentially just wanted to replicate the standard behavior with a custom animation to see how it works.

Here's my example. All I have is a button that navigates to a different page, and I animate an Animated.View as a shared element between the two pages.

import { Text, View } from '@atomic';
import { Button } from '@molecules';
import {
	NavigationContainer,
	RouteProp,
	useNavigation
} from '@react-navigation/native';
import {
	createNativeStackNavigator,
	NativeStackNavigationProp
} from '@react-navigation/native-stack';
import { StackNavigationProp } from '@react-navigation/stack';
import React from 'react';
import { StyleSheet } from 'react-native';
import Animated, {
	SharedTransition,
	withSpring
} from 'react-native-reanimated';

export const Stack = createNativeStackNavigator();

const bouncyTransition = SharedTransition.custom((values) => {
	'worklet';
	return {
		height: withSpring(values.targetHeight),
		width: withSpring(values.targetWidth),
		originX: withSpring(values.targetOriginX),
		originY: withSpring(values.targetOriginY),
		borderRadius: withSpring(values.targetBorderRadius)
	};
});

export type RootStackParamList = {
	HomePage: undefined;
	DetailsPage: undefined;
};

export type HomeScreenNavigationProp = StackNavigationProp<
	RootStackParamList,
	'HomePage'
>;
export type DetailScreenNavigationProp = StackNavigationProp<
	RootStackParamList,
	'DetailsPage'
>;
export type DetailScreenRouteProp = RouteProp<
	RootStackParamList,
	'DetailsPage'
>;

const DetailsPage = () => {
	const navigation =
		useNavigation<NativeStackNavigationProp<RootStackParamList>>();
	const back = () => {
		navigation.goBack();
	};
	return (
		<View flex={1} justifyContent='center'>
			<Text>Details Page</Text>
			<Button text='Back' onPress={back} />
			<Animated.View
				sharedTransitionTag='box'
				sharedTransitionStyle={bouncyTransition}
				style={styles.box2}
			/>
		</View>
	);
};

const HomePage = () => {
	const navigation =
		useNavigation<NativeStackNavigationProp<RootStackParamList>>();
	const goToDetails = () => {
		navigation.navigate('DetailsPage');
	};
	return (
		<View flex={1} justifyContent='center' alignItems='center'>
			<Text>Home Page</Text>
			<Button text='Details' onPress={goToDetails} />
			<Animated.View
				sharedTransitionTag='box'
				sharedTransitionStyle={bouncyTransition}
				style={styles.box1}
			/>
		</View>
	);
};

const styles = StyleSheet.create({
	box1: {
		backgroundColor: 'red',
		borderRadius: 5,
		height: 100,
		width: 100
	},
	box2: {
		backgroundColor: 'red',
		borderRadius: 50,
		height: 200,
		width: 200
	}
});

const TransitionMaster = () => {
	return (
		<NavigationContainer>
			<Stack.Navigator>
				<Stack.Screen name='HomePage' component={HomePage} />
				<Stack.Screen
					name='DetailsPage'
					component={DetailsPage}
					options={{
						presentation: 'transparentModal',
						animation: 'fade'
					}}
				/>
			</Stack.Navigator>
		</NavigationContainer>
	);
};

export default TransitionMaster;

All of this comes from my current project where I was playing around with this. When I tried to reproduce this in a minimal repo, I installed all the latest react native things, and shared transitions weren't even working at all.

The example I'm going to provide is to address the fact that it is not working at all with the latest react native.

Steps to reproduce

1. Install & configure react native, react navigation, react native reanimated
2. Set up a basic shared element transition on an Animate.View

Hi @aymather! Shared Elements Transitions are not yet implemented on the New Architecture, which became the default in RN 0.76.

[aymather]

@bartlomiejbloniarz Oh ok. What about the existing architecture though? Seems like it still isn't stable (per the first video in my post). I could maybe make a minimal repo to reproduce that but what I posted is like the most basic usage of custom transitions. The documentation does seem to allude to the idea that shared transitions aren't exactly super supported yet, but I guess it'd be helpful for us all to know where that's at?
