And remove all styles for TouchableOpacity and Text

Any suggestion would be great, please let me know if anything else is required for better understanding.
you might want to try setting up your onPress similar to the RN documentation for TouchableOpacity (https://reactnative.dev/docs/touchableopacity.html you also may want to consider switching to Pressable for future proofing purposes). You can do
const onPress = () => setModalVisible(true);

How to append new images to the array using react native image crop picker?

Hi, I am using react-native-image-crop-picker to overcome the above-shown module to select images from the gallery and display it in react native app, but I also want to click on add photo and again select images from the gallery and append them to the previous array of photos, am unable to figure that out.

You only need to take the prevState in setAddPhotos
setAddPhotos((lastPhotos) => {
const imagesMap = images.map((i) => {
return {
uri: i.path,
width: i.width,
height: i.height,
mime: i.mime,
};
});
return [...lastPhotos, ...imagesMap];
});

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 app doesn`t fill the whole screen

I can't get my app to fill the whole screen. Whatever i do, there is always a white bar on the bottom of the page. It's so strange because it works on some devices but not others. i'm going crazy over this!
Ive tried const { height, width } = Dimensions.get('window'); and setting the app height with that, and it actually worked once, but now i can't get it to work again. ive tried rewrapping everything in different ways, with different views and scrollviews.
ps.: i removed all functions and useless code so it's not too much code, but

I think you're talking about the image background but not totally sure. I was able to get it to stretch to the full height by adding the following height declaration:
imagemBackground: {
flex: 1,
height: height,
},
link to example: https://snack.expo.io/r1Y-zpwMH
You are using flex:1 many times in style that is the problem.
please give flex:1 in container style and remove all flex:1 in other styles instead of flex:1 you can use width and height in percentage.
like style={{width:'100%',height:'40%'}}.
Thank you!

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!
File1
<View style={styles.container}>
<Head
headerText={this.props.type}
navigation={this.props.navigation}
backButton
/>
<FlatList
data={this.state.data}
renderItem={({ item }) => <RecipeCard {...item} />}
/>
</View>
const styles = {
container: {
flex: 1
}};
RecipeCard
<FastImage
style={styles.imageStyle}
source={{ uri: this.props.image }}
>
<View style={styles.titleContainer}>
<Text style={styles.titleText}>
{this.props.title}
</Text>
<Text style={styles.subtitleText}>
{this.props.subtitle}
</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!
