"React.Children.only expected to receive a single React element child" error when putting <Image> and <TouchableHighlight> in a <View>

It seems that <TouchableHighlight> must have exactly one child. The docs say that it supports only one child and more than one must be wrapped in a <View>, but not that it must have at least (and most) one child. I just wanted to have a plain coloured button with no text/image, so I didn't deem it necessary to add a child.

I'll try to update the docs to indicate this.


The <TouchableHighlight> element is the source of the error. The <TouchableHighlight> element must have a child element.

Try running the code like this:

render() {
    const {height, width} = Dimensions.get('window');
    return (
        <View style={styles.container}>
            <Image 
                style={{
                    height:height,
                    width:width,
                }}
                source={require('image!foo')}
                resizeMode='cover' 
            />
            <TouchableHighlight style={styles.button}>
                <Text> This text is the target to be highlighted </Text>
            </TouchableHighlight>
        </View>
    );
}
