cannot place an image to right side react native - reactjs

I have an image and it should be placed at right side of the header. I have tried and it is working perfectly in android devices. But in IOS the image is showing at left side. Please check my code,
export default class Header extends Component {
constructor(props) {
super(props);
}
render() {
return (
<View style={styles.header}>
<View style={styles.logoContainer}>
<Text style={{textAlign: 'right'}}>
<Image
style={styles.logo}
resizeMode={'contain'}
source={require('../../../../assets/logo.png')}
/>
</Text>
<TouchableOpacity
onPress={() =>
this.props.navigation.navigate('AffiliateInfo')
}
>
<Text style={{textAlign: 'right'}}>
<Image
style={styles.agile}
source={require('../../../../assets/agile.png')}
/>
</Text>
</TouchableOpacity>
</View>
<Image
style={styles.navImage}
source={require('../../../../assets/nav.png')}
/>
</View>
);
}
}
const styles = StyleSheet.create({
header: {
backgroundColor: '#0d2c4f',
paddingLeft: 10,
paddingRight: 10,
paddingTop: 30,
paddingBottom: 30,
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'flex-end'
},
logoContainer: {
flex: 1
},
logo: {
width: 200,
height: 50,
resizeMode: 'contain'
},
agile: {
width: 100,
height: 30,
resizeMode: 'contain'
},
navImage: {
width: 40,
height: 15,
resizeMode: 'contain',
marginLeft: 20
}
});
The logo.png and agile.png image should be placed at right side. Is there anything to be done in IOS. Any solution will be appreciated. I am really stuck in here.

You can use alignItems
< View style={{ alignItems: 'flex-end', width: 100, height: 30 }} >
<Image
style={styles.agile}
source={require('../../../../assets/agile.png')}
/>
< View />

Why my horizontal ScrollView is not working?

I´m trying without success to use the ScrollView component in React Native, below the code:
const width_proportion = '97%';
const height_proportion = '75%';
const styles = StyleSheet.create({
container: {
height: '100%'
},
image: {
flex: 1,
resizeMode: "cover",
justifyContent: "center"
},
text: {
color: "grey",
fontSize: 30,
fontWeight: "bold"
},
popup: {
color: '#CA0',
},
box: {
width: width_proportion,
height: height_proportion,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'steelblue',
// position: "absolute",
marginTop: '5%',
marginBottom: '3%',
marginLeft: '2%'
},
bottomBox: {
width: '97%',
height: 125,
backgroundColor: 'steelblue',
marginLeft: '2%',
marginBottom: 10,
marginTop: 5,
padding: 5
}
});
const MyTheme = {
colors: {
...DefaultTheme.colors,
background: '#EFA',
primary: '#000',
text: '#000',
},
};
function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<View style={{ width: '100%', height: 50, backgroundColor: 'steelblue' }}>
<TouchableOpacity onPress={() => navigation.toggleDrawer()}>
<Image source={hamburgerMenu} style={{ height: 45, width: 45, alignItems: 'center' }}>
</Image>
</TouchableOpacity>
</View>
<ImageBackground source={imgBackground} style={styles.image}>
<View style={styles.box}>
</View>
<ScrollView horizontal={true} >
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
</ScrollView>
</ImageBackground>
</View >
);
}
When I set the horizontal property to "true" from ScrollView, the component disappears. Only I set horizontal to "false" and the ScrollView workks fine in Vertical.
wrap your scrollview like this
<ScrollView horizontal={true}>
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
</ScrollView>
bottomBox : {
width: 40,
height: 125,
backgroundColor: 'steelblue',
padding: 5,
marginRight: 10,
}

(React Native) update the 'fileduration' state for 'React-native-slider' upon fetching the audio file from firebase

TL;DR
It is uncertain that when will the audio file be fetched and given to the trackplayer. So i need a way that will detect the change that the file has been fetched and duration value is now available. I tried playing around with Async/await but it still fails to deliver the duration value on time to the slider.
I am developing an RN app that can stream the audio files that are currently stored in my firebase storage. I am facing difficulty in updating the slider's maximumValue. Since the song takes a couple of seconds to get fetched from firebase, the (total) duration value of the song file given by the react-native-track-player is undefiend and consequently the play button's onPress function setState(duration) sets the new tracklength state as undefined. And this is set as the maximumValue for the slider, which in turn gives the error as shown in the screenshot.
What can i do such that, when the TrackPlayer.getState() (a method from the ProgressComponent) changes its value to 'playing' or 'Ready', the application automatically rerenders with the correct duration value without giving the error.
I have used React-native-slider and React-native-Track-player

Sorry for the messy code but the comments would help a bit in navigating to the main parts like Slider and Play Button
Error:
My Error from the slider
For those who might require an answer to this, I solved the problem using React Hooks. React Native Track Player has a v2 update, in which the converting the above class component to functional component did the trick. It gives a rather accurate results then before. Refer to the docs here.

React Native ScrollView will not expand with child size

I'm building an app which uses the Map method to build several different components. I have a scrollview which contains the whole page. Currently, the scrollView won't expand to contain everything despite trying what is seemingly every bit of advice online.
I have tried having the scrollview be inside another view but that still doesn't work as well as a combination of different flex configurations. Does anyone know why this page in particular isn't working. I have compared it to other pages and there is seemingly no reason as to why the flex does not extend.
Thanks

EDIT: For anyone suffering from the same issue, REMOVE PERCENTAGES FROM HEIGHTS. This fixed this issue for me.
Maybe just use style instead of contentContainerStyle ? the doc says :
These styles will be applied to the scroll view content container which wraps all of the child views
So maybe here is your problem, you're not applying the flexGrow to the scrollView but to its wrapper

React Native: Component not rendering

I am importing a custom component (RecipeCard) and it isn't appearing on the screen.
I'm fairly certain it is to do with the styling that I am currently using.
The fastimage component works exactly as the RN component does and can be seen here.
Any help is appreciated!

</Text>
<Text style={styles.subtitleText}>

</Text>
</View>
</FastImage>
const styles = StyleSheet.create({
imageStyle: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
alignSelf: 'stretch',
backgroundColor: 'transparent',
},
titleContainer: {
position: 'absolute',
marginTop: 15,
zIndex: 2,
bottom: 13,
flex: 1,
width: '100%',
height: 70,
flexDirection: 'column',
alignItems: 'flex-start',
},
titleText: {
color: 'white',
fontWeight: '800',
paddingLeft: 5,
paddingTop: 10
},
subtitleText: {
color: '#adadad',
fontWeight: '500',
paddingLeft: 5,
paddingTop: 5,
}
});
Try to add the resizeMode to the FastImage:
resizeMode={FastImage.resizeMode.contain}
It's also described in the docs of FastImage:
import FastImage from 'react-native-fast-image'
const YourImage = () =>
<FastImage
style={styles.image}
source={{
uri: 'https://unsplash.it/400/400?image=1',
headers:{ Authorization: 'someAuthToken' },
priority: FastImage.priority.normal,
}}
resizeMode={FastImage.resizeMode.contain}
/>
I tried the example you have given above, I was able to see the image with a little change in imageStyle, just added height and it was showing the images.
RecipeCard component
const RecipeCard = (props) => {
return (
<FastImage
style={styles.imageStyle}
source={{ uri: 'https://unsplash.it/400/400?image=1' }}
>
<View style={styles.titleContainer}>
<Text style={styles.titleText}>
{props.title}
</Text>
<Text style={styles.subtitleText}>
{props.subtitle}
</Text>
</View>
</FastImage>
);
}
In imageStyle I have added height
imageStyle: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
alignSelf: 'stretch',
backgroundColor: 'transparent',
height: 200
},
Hope this helps!
