In my App I have a screen that normally looks like this
but when I build for production the title wrapper gets pushed down a few pixels, which results in some strange formatting:
I don't really understand why the app looks different when build for release vs when I develop it. I also tested it on multiple devices but I have the same error on all of them.
import React, { useState, useEffect } from 'react';
import { Text, View, StyleSheet, Button } from 'react-native';
import { BarCodeScanner } from 'expo-barcode-scanner';
import BottomBar from './component/BottomBar';
export default function ScanScreen({ navigation }) {
const [hasPermission, setHasPermission] = useState(null);
useEffect(() => {
(async () => {
const { status } = await BarCodeScanner.requestPermissionsAsync();
setHasPermission(status === 'granted');
})();
}, []);
const handleBarCodeScanned = ({ type, data }) => {
navigation.navigate("Shelf", { shelfID: data.toString() })
};
if (hasPermission === null) {
return <Text>Requesting for camera permission</Text>;
}
if (hasPermission === false) {
return <Text>No access to camera</Text>;
}
return (
<View style={styles.container}>
<View style={styles.contentContainer}>
<View style={styles.titleWrapper}>
<Text style={styles.text}> Shelf Scanner </Text>
</View>
<View style={{flex: 1}}>
<BarCodeScanner
onBarCodeScanned={handleBarCodeScanned}
style={StyleSheet.absoluteFillObject}
/>
</View>
</View>
<BottomBar navigation={navigation} />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#F5FCFF',
flexDirection: 'row',
},
titleWrapper: {
width: '100%',
top: 30,
height: 50,
alignSelf: 'center',
alignItems: 'center',
backgroundColor: '#A2F5AA',
},
text: {
fontSize: 15,
justifyContent: 'center',
fontWeight: 'bold',
flex: 1,
marginTop: 10,
},
contentContainer: {
flex: 1
},
});
I fixed it by removing top: 30, from titleWrapper. The title is now offset in develop mode, but it at least looks correct in the production build
