Not able to navigate to tab while using a custom tab when a new tab/screen is dynamically added at random intervals

[akashgupta17]

Current behavior

Here's my code :

import React, { useEffect, useState } from 'react';
import { Animated, SafeAreaView, StyleSheet, TouchableOpacity, View } from 'react-native';

import { NavigationContainer } from '@react-navigation/native';
import { createMaterialTopTabNavigator } from '@react-navigation/material-top-tabs';

const Tab = createMaterialTopTabNavigator();

function MyTabBar({ state, descriptors, navigation, position }) {
	return (
		<View style={{ flexDirection: 'row' }}>
			{state.routes.map((route, index) => {
				const { options } = descriptors[route.key];
				const label =
					options.tabBarLabel !== undefined
						? options.tabBarLabel
						: options.title !== undefined
						? options.title
						: route.name;

				const isFocused = state.index === index;

				const onPress = () => {
					const event = navigation.emit({
						type: 'tabPress',
						target: route.key,
						canPreventDefault: true,
					});

					if (!isFocused && !event.defaultPrevented) {
						navigation.navigate(route.name, route.params);
					}
				};

				const onLongPress = () => {
					navigation.emit({
						type: 'tabLongPress',
						target: route.key,
					});
				};

				const inputRange = state.routes.map((_, i) => i);
				const opacity = position.interpolate({
					inputRange,
					outputRange: inputRange.map((i) => (i === index ? 1 : 0)),
				});

				return (
					<TouchableOpacity
						accessibilityRole="button"
						accessibilityState={isFocused ? { selected: true } : {}}
						accessibilityLabel={options.tabBarAccessibilityLabel}
						testID={options.tabBarTestID}
						onPress={onPress}
						onLongPress={onLongPress}
						style={{
							flex: 1,
							height: 50,
							backgroundColor: 'green',
							alignItems: 'center',
							justifyContent: 'center',
						}}
					>
						<Animated.Text>{label}</Animated.Text>
					</TouchableOpacity>
				);
			})}
		</View>
	);
}

const HomeScreen = () => {
	return <View style={{ backgroundColor: 'yellow', flex: 1 }}></View>;
};

const SettingsScreen = () => {
	return <View style={{ backgroundColor: 'red', flex: 1 }}></View>;
};

const NewScreen = () => {
	return <View style={{ backgroundColor: 'pink', flex: 1 }}></View>;
};

function MyTabs() {
	const [state, setstate] = useState([
		{ name: 'Home', component: HomeScreen },
		{ name: 'Settings', component: SettingsScreen },
	]);
	useEffect(() => {
		setTimeout(() => {
			const newState = state.slice();
			newState.splice(1, 0, { name: 'New Screen', component: NewScreen });
			setstate(newState);
		}, 15000);
	}, []);
	return (
		<Tab.Navigator tabBar={(props) => <MyTabBar {...props} />}>
			{state.map((item) => {
				return <Tab.Screen key={item.name} name={item.name} component={item.component} />;
			})}
		</Tab.Navigator>
	);
}

const App = () => {
	return (
		<SafeAreaView style={{ flex: 1 }}>
			<NavigationContainer>
				<MyTabs />
			</NavigationContainer>
		</SafeAreaView>
	);
};

const styles = StyleSheet.create({
	sectionContainer: {
		marginTop: 32,
		paddingHorizontal: 24,
	},
	sectionTitle: {
		fontSize: 24,
		fontWeight: '600',
	},
	sectionDescription: {
		marginTop: 8,
		fontSize: 18,
		fontWeight: '400',
	},
	highlight: {
		fontWeight: '700',
	},
});

export default App;

Expected behavior

It should navigate to the tab which is being selected in the video

Reproduction

Create a tab while by a state and add another tab to the state after some time -> while this happens stay on the last tab -> after the new tab is added before the index of the current focused tab -> try to navigate to the newly added tab by not SWIPING but clicking on the tab name in custom tab bar

Hey @akashgupta17! Thanks for opening the issue. It seems that the issue doesn't contain a link to a repro.

The best way to get attention to your issue is to provide an easy way for a developer to reproduce the issue.

You can provide a repro using any of the following:

• Expo Snack
• TypeScript Playground
• GitHub repo under your username

A snack link is preferred since it's the easiest way to both create and share a repro. If it's not possible to create a repro using a snack, link to a GitHub repo under your username is a good alternative. Don't link to a branch or specific file etc. as it won't be detected.

Try to keep the repro as small as possible by narrowing down the minimal amount of code needed to reproduce the issue. Don't link to your entire project or a project containing code unrelated to the issue. See "How to create a Minimal, Reproducible Example" for more information.

You can edit your original issue to include a link to the repro, or leave it as a comment. The issue will be closed automatically after a while if you don't provide a repro.
