React Native Modalize Styling problem (webview/modal) - reactjs

enter image description here
Hello friends, I would like to know how I solve this problem of stylization of Modal / Modalize.. well, it does not fully occupy the width of the screen, these side spacings are appearing. Does anyone have any notion of how to do this? I'm new to React Native, I'm learning from the expo

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];
});

} else {

I hope you guys can find a solution I will keep u guys updated on my progress, I am constantly looking for answers but i don't really understand how to make the delete (X) work and to make it delete a different element, if you know a way to make work better just let me know i would appreciate it a lot
You have to send index to delete function.
renderItem={(itemData,index) => (
<View style={styles.groceryItem} >
<Text style={styles.groceryItemText}>{itemData.item}</Text>
<Text style={styles.groceryItemDelete.bind(index)}>X</Text>
</View>
and example delete function :
groceryItemDelete(index){
setCourseGoals(currentGoals.splice(index,1))
}
You need to implement the delete method and add an onPress event:
renderItem={(itemData, idx) => (
<View style={styles.groceryItem} >
<Text style={styles.groceryItemText}>{itemData.item}</Text>
<Text style={styles.groceryItemDelete} onPress={() => deleteItem(idx)}>X</Text>
</View>
)}
const deleteItem = idx => {
const clonedGoals = [...courseGoals]
clonedGoals.splice(idx, 1)
setCourseGoals(clonedGoals)
}

Getting a navigation.navigate type error after spliting the mainscreen into components

I was working on my app with two screens a Main Screen and a Details Screen everything was working, but the code was long, so I tried to split everything into reusable components which caused a

My apologies for the long samples of code I tried to keep everything that is connected directly to the problem.
The problem is the you are accessing navigation outside the navigation stack. When you moved the flatlist to to ArticleList its outside the navigation and it wont get the navigation prop.
You can handle this in two ways.
You can simply pass the navigation from the main screen
function MainScreen({ navigation }) {
return (
{/* show the data in a flatlist */}
< ArticleList navigation={navigation} />
);
}
You can use the useNavigation hook to access navigation outside navigation.
