React Native Alert doesn't accept Navigation in my code

I'm trying to add a navigation in this Alert with Dialog, in the 'OK' option to confirm Logout and go back to the login screen, however it's not working. Does anyone help me with this?
I'm also trying to insert a dark theme for the entire application, local expo finger printing and push notifications in setData options 2, 3, and 4, but it's a difficult task as well.. But I'm more focused on creating this Navigation in my Alert because I'm trying.
i'll be very grateful for the help :)
when I grow up, I'm going to be a great programmer.

Your mistake is because of your onPress={()=> (handleLogout)}. onPress takes in a function but in your case you are making the function run another function, so your alert will not even be activated. To fix this, simply change your code to this.
onPress={handleLogout}

React Native: How do I switch the state of only one item in FlatList?

what happens is the following fact: I want to add "switch/toggle" next to id 2.3 and 4 items, but it's getting on all items on the flatlist. I used "import SwitchSelector from "react-native-switch-selector"; " Can anyone who understands flatlist help me? I will be very happy and grateful
I'm not getting it at all, and I'm thinking of redoing my code because of this problem
Settings.js
import { SafeAreaView,Text, View, FlatList,
TouchableOpacity, StyleSheet, Image} from 'react-native';
import SwitchSelector from "react-native-switch-selector";
import React, {useState} from 'react'
const Settings = () => {
const [data, setdata] = useState(DATA);
const [isRender, setisRender] = useState(false);
const DATA = [
{id: 1, text: 'Perfil', image: require('../../assets/images/user.png')},
{id: 2, text: 'Dark/Light mode', image: require('../../assets/images/light-up.png')},
{id: 3, text: 'TouchId', image: require('../../assets/images/fingerprint.png')},
{id: 4, text: 'Notificações', image: require('../../assets/images/bell-fill.png')},
//{id: 5, text: 'Logout'},
]
const renderItem = ({item}) => {
return(
<TouchableOpacity style= {styles.item}>
<View style={ styles.avatarContainer }>
<Image source={ item.image } style={ styles.avatar } />
</View>
<View>
<Text style={styles.text}>{item.text}</Text>
</View>
</TouchableOpacity>
)
}
return (
<SafeAreaView style={styles.container}>
<FlatList
data={DATA}
keyExtractor={(item) => item.id.toString()}
renderItem={renderItem}
extraData={isRender}
/>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
marginTop: 20
//marginHorizontal: 21
},
item:{
borderBottomWidth: 1,
borderBottomColor: '#808080',
alignItems: 'flex-start',
flexDirection: 'row',
},

Well here is my approach to your problem as much as I understood;
it also actively changes the values of data for further usage of App
const [data, setData] = useState([
{ id: 1, text: 'Perfil', image: require('../../assets/images/user.png'), chosen: false },
{ id: 2, text: 'Dark/Light mode', image: require('../../assets/images/light-up.png'), chosen: false },
{ id: 3, text: 'TouchId', image: require('../../assets/images/fingerprint.png'), chosen: false },
{ id: 4, text: 'Notificações', image: require('../../assets/images/bell-fill.png'), chosen: false },
//{id: 5, text: 'Logout'},
])
const [isRender, setisRender] = useState(false);
const renderItem = ({ item }) => {
return (
<TouchableOpacity style={styles.item}>
<View style={styles.avatarContainer}>
<Image source={item.image} style={styles.avatar} />
</View>
<View>
<Text style={styles.text}>{item.text}</Text>
</View>
{item.id > 1 && <Switch
thumbColor={item.chosen == false ? "red" : "green"}
value={item.chosen}
onChange={() => setData(data.map(index =>
item.id === index.id
? {...index, chosen : !index.chosen}
: index
))}
/>}
</TouchableOpacity>
)
}
return (
<SafeAreaView style={styles.container}>
<FlatList
data={data}
keyExtractor={(item) => item.id.toString()}
renderItem={renderItem}
extraData={isRender}
/>
</SafeAreaView>
);};
You could try adding a boolean property to each item in DATA. You could then conditionally show a <SwitchSelector /> in renderItem based on that property.
For example, below I added the property showSwitch and used a ternary expression to conditionally show a <SwitchSelector /> in renderItem:
const DATA = [
{id: 1, text: 'Perfil', image: require('../../assets/images/user.png'), showSwitch: false},
{id: 2, text: 'Dark/Light mode', image: require('../../assets/images/light-up.png'), showSwitch: true},
{id: 3, text: 'TouchId', image: require('../../assets/images/fingerprint.png'), showSwitch: true},
{id: 4, text: 'Notificações', image: require('../../assets/images/bell-fill.png'), showSwitch: true},
//{id: 5, text: 'Logout'}
]
...
const renderItem = ({ item }) => {
return (
<TouchableOpacity style={styles.item}>
<View style={styles.avatarContainer}>
<Image source={item.image} style={styles.avatar} />
</View>
<View>
<Text style={styles.text}>{item.text}</Text>
</View>
{item.showSwitch ? <SwitchSelector /> : null}
</TouchableOpacity>
);
};
This works from me:
import { SafeAreaView,Text, View, FlatList,
TouchableOpacity, StyleSheet, Image, Switch} from 'react-native';
import React, {useState, useEffect} from 'react';
import {TouchID} from 'react-native-touch-id';
const Settings = () => {
const [data, setdata] = useState(DATA);
const [isRender, setisRender] = useState(false);
const DATA = [
{id: 1, text: 'Perfil', image: require('../../assets/images/user.png'), switch: false},
{id: 2, text: 'Dark/Light mode', image: require('../../assets/images/light-up.png'), switch: true},
{id: 3, text: 'TouchId', image: require('../../assets/images/fingerprint.png'), switch: true},
{id: 4, text: 'Notificações', image: require('../../assets/images/bell-fill.png'), switch: true},
//{id: 5, text: 'Logout'}
]
const renderItem = ({item}) => {
return(
<TouchableOpacity
style= {styles.item}
>
<View style={ styles.avatarContainer }>
<Image source={ item.image } style={ styles.avatar } />
</View>
<View>
<Text style={styles.text}>{item.text}</Text>
</View>
{item.switch ? <Switch /> : null}
</TouchableOpacity>
)
}
return (
<SafeAreaView style={styles.container}>
<FlatList
data={DATA}
keyExtractor={(item) => item.id.toString()}
renderItem={renderItem}
extraData={isRender}
/>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
marginTop: 20
//marginHorizontal: 21
},
item:{
borderBottomWidth: 1,
borderBottomColor: '#808080',
alignItems: 'flex-start',

},

You may want to lift the checkbox state to the parent component, i.e. make the checkboxes controlled, and collect the checked checkbox values. For this I'm assuming your data items have an id property, but any unique item property will suffice.
Example:
export function CheckBoxCustom({ checked, onPress }) {
return (
<SafeAreaView>
<TouchableOpacity
style={{
backgroundColor: "white",
width: 20,
height: 20,
borderWidth: 2,
borderColor: "#ddd",
}}
onPress={onPress}
>
{checked ?? <IconAntDesign name="check" size={15} color={"black"} />}
</TouchableOpacity>
</SafeAreaView>
);
}
...
const [checked, setChecked] = useState({});
const checkToggle = id => {
setChecked(checked => ({
...checked,
[id]: !checked[id],
}));
};
const renderItem = ({ item, index }) => {
return (
<View>
<View style={{ flexDirection: "row" }}>
<CheckBoxCustom
checked={checked[item.id]}
onPress={() => checkToggle(item.id)}
/>
<Text style={{ marginLeft: 10 }}>{item.name}</Text>
</View>
</View>
);
};
<FlatList
data={dataList}
keyExtractor={(e, i) => i.toString()}
renderItem={renderItem}
ItemSeparatorComponent={separator}
/>;
If your data hasn't any good GUID candidates then I suggest augmenting your data to include good GUIDs.
To pass the checked/selected items filter the dataList array.
Example:
const selected = dataList.filter(
item => checked[item.id]
);
// pass selected in navigation action

how can I scroll the full screen with a tab view?

Try this way
function handlePick(item){
const route = `Screen${item.value}`; // dynamic screen like 'ScreenA' or 'ScreenB' etc...
navigation.navigate(route, {data: item} ); This way will navigate to route with data object of item
}
