I'm getting this error.[ErrorImg][1] This is Require cycles error but I can't find what is the reason. I want to use ListItem component to View.js through component.js and I already use that like this import {ListItem } from '../components/';. The result is good but there is this warning and I want to fix. Please help me.
Require cycle: Components.js->
import Button from './Button';
import Select from './Select';
import Icon from './Icon';
import Tabs from './Tabs';
import Product from './Product';
import Drawer from './Drawer';
import Header from './Header';
import Switch from './Switch';
import ListItem from './ListItem';
import HorizontalListItem from './HorizontalListItem';
export {
Button,
Select,
Icon,
Tabs,
Product,
Drawer,
Header,
Switch,
ListItem,
HorizontalListItem,
};```
View.js->
```const renderPatientsList = () => {
return(
<Block style={{ paddingHorizontal: theme.SIZES.BASE }}>
<ScrollView vertical={true} showsVerticalScrollIndicator={false} style={{marginBottom: theme.SIZES.BASE * 3}}>
<ListItem product={products[0]} horizontal />
<ListItem product={products[1]} horizontal />
<ListItem product={products[2]} horizontal />
</ScrollView>
</Block>
)
}```
ListItem.js -->
```import React from 'react';
import { withNavigation } from '@react-navigation/compat';
import { StyleSheet, Dimensions, Image, TouchableWithoutFeedback } from 'react-native';
import { Block, Text, theme } from 'galio-framework';
import { Icon } from '../components/';
import { LinearGradient } from 'expo-linear-gradient';
const { width } = Dimensions.get('screen');
const ListItem = props => {
const { navigation, product, horizontal, full, style, priceColor, imageStyle, time, unReaden, weekday } = props;
const imageStyles = [styles.image, full ? styles.fullImage : styles.horizontalImage, imageStyle];
return (
<Block row={horizontal} card flex style={[styles.product, styles.shadow, style]}>
<TouchableWithoutFeedback onPress={() => navigation.navigate('Product', { product: product })}>
<Block style={[styles.imageContainer, styles.shadow]}>
<Image source={{ uri: product.image }} style={imageStyles}/>
</Block>
</TouchableWithoutFeedback>
<TouchableWithoutFeedback onPress={() => navigation.navigate('Product', { product: product })}>
<Block flex={3}>
<Text size={16} style={styles.userName}>{product.title}</Text>
<Block flexDirection={'row'}>
<Icon name="photo" family="font-awesome" color={theme.COLORS.MUTED} size={theme.SIZES.BASE} style={styles.icons}> </Icon>
<Icon name="check" family="font-awesome" color={theme.COLORS.MUTED} size={theme.SIZES.BASE} style={styles.icons}> </Icon>
<Text size={16} muted={!priceColor} color={priceColor}>${product.price}</Text>
</Block>
</Block>
</TouchableWithoutFeedback>
<TouchableWithoutFeedback onPress={() => navigation.navigate('Product', { product: product })}>
<Block flex={1}>
<>
{(product.time) ? (
<Text size={12} style={styles.times} color={"#06D81E"}>{product.time}</Text>
) : (
<Text size={12} style={styles.times} color={"#000"}>{product.weekday}</Text>
)}
</>
<Block style={{borderRadius: 100, backgroundColor: "#06D81E", width: theme.SIZES.BASE * 1.2, height: theme.SIZES.BASE * 1.2, position: "absolute", right: theme.SIZES.BASE, bottom: theme.SIZES.BASE}}>
<Text size={12} center style={{justifyContent: 'center', alignItems: 'center'}} color={"#FFF"} fontWeight={"semiBold"}>{product.unReaden}</Text>
</Block>
</Block>
</TouchableWithoutFeedback>
</Block>
);
}```

You are getting require cycle warning because you end up creating a loop ( require from Component.js
in ListItem.js
and require from ListItem.js
in Component.js
)
In ListItem.js
,
import {Icon} from Icon.js
The general idea is to write the module in another file and import that module from there.
see this for a detailed explanation: Require cycles are allowed, but can result in uninitialized values. Consider refactoring to remove the need for a cycle
