Using react native with a flex of 50% may lead to unexpected errors

Question

Using react native with a flex of 50% may lead to unexpected errors

Currently in the process of learning react native.

Below is the code I am working with:

<View>
    <View style={{flex:0.5,flexDirection="row"}}>
        <Image source={{uri:"http://image.com/image1.jpg"}} style={{width:100,height:'auto'}} resizeMode={"cover"} />
        <Text>Picture 1</Text>
    </View>
    <View style={{flex:0.5,flexDirection="row"}}>
        <Image source={{uri:"http://image.com/image2.jpg"}} style={{width:100,height:'auto'}} resizeMode={"cover"} />
        <Text>Picture 2</Text>
    </View>
    <View style={{flex:0.5,flexDirection="row"}}>
        <Image source={{uri:"http://image.com/image3.jpg"}} style={{width:100,height:'auto'}} resizeMode={"cover"} />
        <Text>Picture 3</Text>
    </View>
    <View style={{flex:0.5,flexDirection="row"}}>
        <Image source={{uri:"http://image.com/image4.jpg"}} style={{width:100,height:'auto'}} resizeMode={"cover"} />
        <Text>Picture 4</Text>
    </View>
</View>

However, upon running this code, an error message is displayed stating that the line

<View style={{flex:0.5, flexDirection:"row"}}>

"is an unexpected token".

Attempts to replace 0.5 with both 50% and "0.5" have also resulted in errors.

If we were to compare this to html css for a web page, the desired outcome would be:

<div>
    <div style="width:50%; float:left;">
        <img src="http://image.com/image1.jpg" style="width:100%; height:auto;" />
        <span>Picture 1</span>
    </div>
    <div style="width:50%; float:left;">
        <img src="http://image.com/image2.jpg" style="width:100%; height:auto;" />
        <span>Picture 1</span>
    </div>
    <div style="width:50%; float:left;">
        <img src="http://image.com/image3.jpg" style="width:100%; height:auto;" />
        <span>Picture 1</span>
    </div>
    <div style="width:50%; float:left;">
        <img src="http://image.com/image4.jpg" style="width:100%; height:auto;" />
        <span>Picture 1</span>
    </div>
</div>

To put it simply, my goal is to display two columns of thumbnail images with captions below each image.

Answer №1

To create a container with children in a row layout, set flexDirection to 'row' and give each child half of the screen's width without allowing them to grow using flexBasis. Here is an example:

<View>
<View style={{flexDirection="row"}}>
    <Image source={{uri:"http://image.com/image1.jpg"}} style={{flexBasis:Dimensions.get('window').width / 2, flexGrow:0}} resizeMode={"cover"} />
    <Text {{flexBasis:Dimensions.get('window').width / 2, flexGrow:0}}>Picture 1</Text>
</View>

Answer №5

The approach suggested by MdBalal is not effective. Using flex:0.5 in React Native does not yield the same results as in standard web development. It may encounter issues when there are more than 2 child components within a container. One workaround is to group children into pairs in one container. For example:

If we have 3 child components in a Container,
**Before**:
<Container><Child/><Child/><Child/></Container>

**After**:
<Container><Child/><Child/></Container> and 
<Container><Child/><EmptyPlaceholder/></Container>
