React Native SyntaxError "," - ios

Receiving syntax error, SyntaxError: Unexpected token, expected ",". It is for the third to last line ");"
I am having trouble seeing where I need to insert the ",". I have tried in front of the ); and after. No luck. This is while I was adding the code for google sign in for ios. Would appreciate any assistance.

React conditional rendering
render() {
const isLoggedIn = this.state.isLoggedIn;
return (
<div>
{isLoggedIn
? <LogoutButton onClick={this.handleLogoutClick} />
: <LoginButton onClick={this.handleLoginClick} />

);
}
You need to add the other half (false case) to the ternary. In this case if you do not want to render anything you need to return null.
render() {
LayoutAnimation.easeInEaseOut();
const scrollEnabled = this.state.screenHeight > height;
return (this.state.logedin ?

React Native Flatlist shows a blank space in tvOS

I'm trying to show a flatList in tvOS and when the flatlist is rendered it shows unwanted space at the top of the rendered items inside the flatlist. This issue is not happening in Android TV or Fire TV.
My code :
<SafeAreaView
style={{
flex: 1,
backgroundColor: Colors.APP_BACKGROUND,
flexDirection: 'row',
}}>
<View style={{width: '27%'}}>
<View
style={[{flex: 1, marginLeft: Platform.OS === 'android' ? '10%' : '5%', marginRight: '10%', marginTop: '10%'}]}>
<Text
style={[
{
fontSize: FontSize.large,
color: Colors.WHITE,
fontFamily: FontFamily.bold,
marginBottom: '5%',
paddingHorizontal: ms(10),
marginLeft: Platform.OS === 'android' ? ms(5) : ms(2),
},
]}>
Settings
</Text>
<FlatList
data={pages}
renderItem={({item, index}) => renderSettingItem(item, index)}
removeClippedSubviews={false}
/>
</View>
</View>
<View
style={{
backgroundColor: Colors.SEPARATOR_SETTING_PAGE,
width: 3,
marginTop: '2%',
height: '60%',
}}
/>
<View style={{width: '73%'}}>
<SettingPageComponent page={page} />
</View>
</SafeAreaView>
I don't know what I did wrong. I'd really appreciate some help. Thanks !

How to extend image across width of screen?

I am attempting to make the images scroll horizontally. I downloaded some UI, and added ScrollView horizontal. But instead of it looking the same just with the ability to scroll horizontally, it shrank the image (and also gave it the ability to scroll horizontally). What should I change to make it stretch all the way across (still with the padding)?
Posts.js
import React from "react";
import {
View,
Text,
Image,
ImagBackground,
ImageBackground,
} from "react-native";
import Icon from "#expo/vector-icons/Entypo";
import { ScrollView, TouchableOpacity } from "react-native-gesture-handler";
export default class Posts extends React.Component {
state = {
liked: false,
};
onLike = () => {
this.setState({ liked: !this.state.liked });
};
render() {
const { name, profile, photo, onPress } = this.props;
return (
<View>
<View
style={{
flexDirection: "row",
paddingTop: 25,
alignItems: "center",
}}

<View style={{ width: "20%" }}>

Here's me adding more words because the post doesn't have enough words on it's own. When will they finally remove this pointless feature? I feel as if I clearly expressed my question with the few words I used.
I believe your issue is with your View wrapping your ScrollView. There is no need of wrapping ScrollView, that too in row, due to which the remaining space is visible. Just define the ScrollView, and it would work just fine. Give a width of 100% to your ScrollView though.
For any sort of styling to the parent for the ScrollView, do it inside the ScrollView itself, like the way I did in the code.
Please note ScrollView accepts a list of child items, currently I see only a single item, if you've intentionally added this one, then it is fine, else, you need to refactor your code surely. This won't work out for you.
// PLEASE NOTE --> Commented Lines should be removed, and
// only ScrollView should be considered with the styling specified
// <View
// style={{
// flexDirection: "row",
// width: "100%",

How can I display more elements in a react native View?

I would like to show on the homepage of my react native app , a view that in turn shows a text element and an icon, then below these 2 I would like to show the amazon logo. I tried but it only shows me the logo.
export default class Header extends Component {
render() {
return (
<View style={{ flex: 1, flexDirection: 'row' }}>
<Text style={styles.Title}>Acquista!</Text>
<Ionicons name="ios-contact" size={42} color='red' style={{ marginTop:
65, marginLeft: 210 }} />
</View> ,
<Logo></Logo>
);
}
}
class Logo extends Component {
render() {
return (
<View>
<Image
style={{ height: 200, width: 200, marginTop: 150 }}
source={require('./assets/images/amazon.jpg')}
/>
</View>
);
}
}
Wrap everything into a View
return (
<View style={{ flex: 1 }}>
<View style={{ flex: 1, flexDirection: 'row' }}>
<Text style={styles.Title}>Acquista!</Text>
<Ionicons name="ios-contact" size={42} color='red' style={{ marginTop: 65, marginLeft: 210 }} />
</View>
<Logo />
</View>
)

React Native KeyboardAvoidingView not working properly

I am trying to use the KeyboardAvoidingView with behavior="padding".
When I am trying to enter any text in TextInput, the TextInput field is not moving up. I have added a small view in the end which is moving up but the the view above it.
I have also with KeyboardAvoidingView height property with offset. It was working few components like 2 TextInputs. But when I add all the components the UI goes insane and behave jumbled up.
Any any idea whats happening over here?
Here the link of tutorial which I have followed.
render() {
return (
<View style={styles.backgroundContainer}>
<Loader
loading={this.state.isLoading} />

I used KeyboardAvoidingView, it also doesn't work.
I found this solution, You can take the base code.
Installation
npm i react-native-keyboard-aware-scroll-view --save
Usage
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>
You can find it here
The way it worked for me was to use position as behavior and -70 as vertical offset. Any non negative integer was creating a huge unused space when the keyboard pops up.
<KeyboardAvoidingView
style={styles.container}
behavior={Platform.OS === 'ios' ? 'position' : 'height'}
keyboardVerticalOffset={Platform.OS === 'ios' ? -70 : 70}
enabled>
<ScrollView>
...
</ScrollView>
</KeyboardAvoidingView>
<KeyboardAvoidingView
style={styles.mainContainer}
behavior="padding"
enabled
>
<View>.......................</View>
</KeyboardAvoidingView>
'Enabled or disabled KeyboardAvoidingView' should be add.
Keep in mind is always your top Parent with flex:1 then the child is then you text input container
<KeyboardAvoidingView style={{ flex: 1 }}
behavior={Platform.OS === "ios" ? "position" : null} enabled>
<ScrollView>
<View>
<View >
<Text maxFontSizeMultiplier={1.5} >
Sign in to your account{" "}
</Text>
<View
behavior="padding"
enabled
>
<TextInput
placeholder="Email address"
placeholderTextColor={Colors.grey}
style={styles.textInput}
onChangeText={(e) => setEmail(e.trim())}
autoCapitalize="none"
returnKeyType={"done"}
/>
</View>
</View>
</ScrollView>
</KeyboardAvoidingView>
// 2nd Solutions use this package
npm i react-native-keyboard-aware-scroll-view --save
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>

KeyboardAvoidingView - can Inputs be wrapped in other Views?

When I wrap my inputs around other views, KeyboardAvoidingView seems to not work at all. Is it general case that inputs must be bare without any containers?
return (
<KeyboardAvoidingView
style={{ backgroundColor: '#fff', flex: 1 }}
behavior="padding"
>
<View style={{ paddingTop: 30, paddingBottom: 10 }}>
<Text style={styles.regularTextStyle}> Twój email </Text>
</View>
<CardInput>
<Input
label="email"
placeholder="jan.kowalski#gmail.com"
value={this.props.email}
onChangeText={text => this.props.dataUpdate({ prop: 'email', value: text })}
/>
</CardInput>
<View style={{ paddingTop: 60, paddingBottom: 10 }}>
<Text style={styles.regularTextStyle}> Adres sklepu</Text>
</View>
<CardInput>
<Input
placeholder="miasto"
value={this.props.city}
onChangeText={text => this.props.dataUpdate({ prop: 'city', value: text })}
/>
</CardInput>
<CardInput>
<Input
placeholder="ulica"
value={this.props.street}
onChangeText={text => this.props.dataUpdate({ prop: 'street', value: text })}
style={{ flex: 3 }}
/>
<Input
placeholder="nr"
value={this.props.number}
onChangeText={text => this.props.dataUpdate({ prop: 'number', value: text })}
style={{ flex: 1, marginLeft: 15 }}
/>
</CardInput>
{this.renderButton()}
<View style={{ height: 60 }} />
</KeyboardAvoidingView>
);
and after keyboard pops up, the view does not go up at all
