Passing style to my custom component is not working in react native. (styles are not attached to my custom component)

I am new to react native.
I created some custom components in project. And I pass some style to them via the props but my passing styles are not attached to that components. At the first it was working correctly but suddenly I don't know what happened that my passing styles are not working.
Here is my code:
This the page where I used my custom component and passed style to that.
function StartGameScreen(props) {
const [confirmed, setConfirmed] = useState(false);
const [selectedNumber, setSelectedNumber] = useState();
const numInputHandler = (inputText) => {
setEneteredValue(inputText.replace(/[^0-9]/g, ""));
};
const confirmInput = () => {
const chosenNumber = parseInt(enteredValue);
if (isNaN(chosenNumber) || chosenNumber <= 0 || chosenNumber > 99) {
Alert.alert(
"Invalid number!",
"Number has to be a number between 0 and 99.",
[{ text: "Okay", style: "destructive", onPress: resetInput }]
);
return;
}
setConfirmed(true);
setSelectedNumber(chosenNumber);
setEneteredValue("");
Keyboard.dismiss();
};
let confirmedOutput;
if (confirmed) {
confirmedOutput = (
<Card style={styles.summeryContainer}>
<Text>You selected</Text>
<NumberContainer>{selectedNumber}</NumberContainer>
<Button
title="START GAME"
onPress={() => {
console.log("hello" + selectedNumber);
props.onStartGame(selectedNumber);
}}
/>
</Card>
);
}
return (
<TouchableWithoutFeedback
onPress={() => {
Keyboard.dismiss();
}}
>
<View style={styles.container}>
<Text style={styles.title}>Start A New Game!</Text>
*This is where I used my custom component (<Card>).*
<Card style={styles.inputContainer}>
<Text>select a number</Text>
<Input
style={styles.input}
blurOnSubmit
autoCapatilize="none"
autoCorrect={false}
keyboardType="number-pad"
maxLength={2}
onChangeText={numInputHandler}
value={enteredValue}
/>
<View style={styles.buttonCon}>
<View style={styles.button}>
<Button
title="Reset"
color={Colors.accent}
onPress={resetInput}
/>
</View>
<View style={styles.button}>
<Button
title="Confirm"
color={Colors.primary}
onPress={confirmInput}
/>
</View>
</View>
</Card>
{confirmedOutput}
</View>
</TouchableWithoutFeedback>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 10,
alignItems: "center",
},
inputContainer: {
width: 300,
maxWidth: "80%",
alignItems: "center",
},
input: {
textAlign: "center",
width: 50,
},
});
export default StartGameScreen;
And this is my Card custom component:
function Card(props) {
return (
<View style={{ ...styles.container, ...props.style }}>
{props.children}
</View>
);
}
const styles = StyleSheet.create({
container: {
shadowColor: "black",
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.26,
shadowRadius: 6,
elevation: 12,
backgroundColor: "white",
padding: 20,
borderRadius: 10,
},
});
export default Card;

Change Your Card component like below then it will work
function Card(props) {
return (
<View style={[styles.container,props.style]}>
{props.children}
</View>
);
}

configuration with the .map() in arrays. Fetching data from firebase and outputting in a tinder-like card view in React Native

Here, I am fetching data from firebase and then trying to output it in a tinder card like format. My code is as follows -
import React from 'react';
import { View, ImageBackground, Text, Image, TouchableOpacity } from 'react-native';
import CardStack, { Card } from 'react-native-card-stack-swiper';
import City from '../components/City';
import Filters from '../components/Filters';
import CardItem from '../components/CardItem';
import styles from '../assets/styles';
import Demo from '../assets/demo';;
import {db} from '../config/config';
class Home extends React.Component {
constructor (props) {
super(props);
this.state = ({
items: [],
isReady: false,
});
}
componentWillMount() {
let items = [];
db.ref('cards').once('value', (snap) => {
snap.forEach((child) => {
let item = child.val();
item.id = child.key;
items.push({
name: child.val().pet_name,
description: child.val().pet_gender,
pet_age: child.val().pet_age,
pet_breed: child.val().pet_breed,
photoUrl: child.val().photoUrl,
});
});
//console.log(items)
this.setState({ items: items, isReady: true });
console.log(items);
});
}
componentWillUnmount() {
// fix Warning: Can't perform a React state update on an unmounted component
this.setState = (state,callback)=>{
return;
};
}
render() {
return (
<ImageBackground
source={require('../assets/images/bg.png')}
style={styles.bg}
>
<View style={styles.containerHome}>
<View style={styles.top}>
<City />
<Filters />
</View>
<CardStack
loop={true}
verticalSwipe={false}
renderNoMoreCards={() => null}
ref={swiper => {
this.swiper = swiper
}}
>
{this.state.items.map((item, index) => (
<Card key={index}>
<CardItem
//image={item.image}
name={item.name}
description={item.description}
actions
onPressLeft={() => this.swiper.swipeLeft()}
onPressRight={() => this.swiper.swipeRight()}
/>
</Card>
))}
</CardStack>
</View>
</ImageBackground>
);
}
}
export default Home;
I am fetching data and storing it in an array called items[]. Console.log(items) gives me the following result:
Array [
Object {
"description": "male",
"name": "dawn",
"pet_age": "11",
"pet_breed": "golden retriever",
"photoUrl": "picture",
},
Object {
"description": "Male",
"name": "Rambo",
"pet_age": "7",
"pet_breed": "German",
"photoUrl": "https://firebasestorage.googleapis.com/v0/b/woofmatix-50f11.appspot.com/o/pFkdnwKltNVAhC6IQMeSapN0dOp2?alt=media&token=36087dae-f50d-4f1d-9bf6-572fdaac8481",
},
]
Furthermore, I want to output my data in a card like outlook so I made a custom component called CardItem:
import React from 'react';
import styles from '../assets/styles';
import { Text, View, Image, Dimensions, TouchableOpacity } from 'react-native';
import Icon from './Icon';
const CardItem = ({
actions,
description,
image,
matches,
name,
pet_name,
pet_gender,
pet_age,
onPressLeft,
onPressRight,
status,
variant
}) => {
// Custom styling
const fullWidth = Dimensions.get('window').width;
const imageStyle = [
{
borderRadius: 8,
width: variant ? fullWidth / 2 - 30 : fullWidth - 80,
height: variant ? 170 : 350,
margin: variant ? 0 : 20
}
];
const nameStyle = [
{
paddingTop: variant ? 10 : 15,
paddingBottom: variant ? 5 : 7,
color: '#363636',
fontSize: variant ? 15 : 30
}
];
return (
<View style={styles.containerCardItem}>
{/* IMAGE */}
<Image source={image} style={imageStyle} />
{/* MATCHES */}
{matches && (
<View style={styles.matchesCardItem}>
<Text style={styles.matchesTextCardItem}>
<Icon name="heart" /> {matches}% Match!
</Text>
</View>
)}
{/* NAME */}
<Text style={nameStyle}>{name}</Text>
{/* DESCRIPTION */}
{description && (
<Text style={styles.descriptionCardItem}>{description}</Text>
)}
{/* STATUS */}
{status && (
<View style={styles.status}>
<View style={status === 'Online' ? styles.online : styles.offline} />
<Text style={styles.statusText}>{pet_age}</Text>
</View>
)}
{/* ACTIONS */}
{actions && (
<View style={styles.actionsCardItem}>
<View style={styles.buttonContainer}>
<TouchableOpacity style={[styles.button, styles.red]} onPress={() => {
this.swiper.swipeLeft();
}}>
<Image source={require('../assets/red.png')} resizeMode={'contain'} style={{ height: 62, width: 62 }} />
</TouchableOpacity>
<TouchableOpacity style={[styles.button, styles.orange]} onPress={() => {
this.swiper.goBackFromLeft();
}}>
<Image source={require('../assets/back.png')} resizeMode={'contain'} style={{ height: 32, width: 32, borderRadius: 5 }} />
</TouchableOpacity>
<TouchableOpacity style={[styles.button, styles.green]} onPress={() => {
this.swiper.swipeRight();
}}>
<Image source={require('../assets/green.png')} resizeMode={'contain'} style={{ height: 62, width: 62 }} />
</TouchableOpacity>
</View>
</View>
)}
</View>
);
};
export default CardItem;
The problem is when I try to pass the data in my items[] array, the cardItem component just doesnt work. To dry-run, I used a sample demo array and when I use the Demo array, my component works just fine. What am I doing wrong? I have been tinkering with this problem for quite a while now. Any help whatsoever would be appreciated.

Search bar glitching out in React Native

I'm making a search bar that displays results live. I've managed to do it properly utilizing SearchBar from 'react-native-elements'. Firstly I had it written as a class component, but decided to rewrite it as a functional component. After rewriting it I'm encountering a bug where the keyboard closes after one letter as seen in the video here
Here is the code of the component
import React, { Component, useEffect, useState } from "react";
import { View, Text, FlatList, TextInput, ListItem } from "react-native";
import { SearchBar } from "react-native-elements";
import { Button } from 'react-native-paper'
import Header from "../navigation/Header";
export default function AktSelect() {
const [data, setData] = useState([])
const [value, setValue] = useState('')
const [akt, setAkt] = useState([])
useEffect(() => {
fetch("http://192.168.5.12:5000/aktprikaz", {
method: "get"
})
.then(res => res.json())
.then(res => setAkt(res));
}, []);
function renderSeparator() {
return (
<View
style={{
height: 1,
width: "100%",
backgroundColor: "#CED0CE"
}}
/>
);
}
function searchItems(text) {
const newData = akt.filter(item => {
const itemData = `${item.title.toUpperCase()}`;
const textData = text.toUpperCase();
return itemData.indexOf(textData) > -1;
});
setData(newData)
setValue(text)
}
function renderHeader() {
return (
<SearchBar
placeholder=" Type Here...Key word"
onChangeText={text => searchItems(text)}
value={value}
lightTheme={true}
/>
);
}
return (
<View
style={{
flex: 1,
width: "98%",
alignSelf: "center",
justifyContent: "center"
}}
>
<Header title='Pretraživanje aktivnosti' />
<FlatList
data={data}
renderItem={({ item }) => (
<View style={{flex: 1}}>
<Text style={{ padding: 10 }}>{item.title} </Text>
<View style={{flexDirection:'row'}}>
<Text style={{ padding: 10 }}>{item.start_time} </Text>
<Button style={{justifyContent: 'flex-end', alignContent: 'flex-end', width:'30%'}} mode='contained' onPress={() => console.log('hi')}>hi</Button>
</View>
</View>
)}
keyExtractor={item => item.id.toString()}
ItemSeparatorComponent={renderSeparator}
ListHeaderComponent={renderHeader}
/>
</View>
);
}
The old class component can be found here

onpress stops working when loading new items react-native Android

I tried changing the execution orders,
setting timeout and when I manually filled out the order array was that I realized that the problem is at that point, but I can't see what I'm doing wrong.

Error : Below is the code, please check Can't find variable itemData
in react-native
Pls i am a newbie in react-native i just got for about two hours. Any
help would be appreciated. Thanks in advance. Look into the code and share some advice so that the code works well..
Thanks :)

It should be
<FlatList keyExtractor={(item, index) => item.id}
data={courseGoals}
renderItem={(itemData) => <GoalItem title={itemData.item.value} }/>
Or
<FlatList keyExtractor={(item, index) => item.id}
data={courseGoals}
renderItem={({item}) => <GoalItem title={item.value} }/>

it should be like this :
<FlatList
data={courseGoals}
renderItem={itemData => (
<View style={styles.listItem}>
<Text>{itemData.item}</Text>
</View>
)}
/>
