React native text going off my screen, refusing to wrap. What to do?

This is a known bug. flexWrap: 'wrap' didn't work for me but this solution seems to work for most people

Code

<View style={styles.container}>
    <Text>Some text</Text>
</View>

Styles

export default StyleSheet.create({
    container: {
        width: 0,
        flexGrow: 1,
        flex: 1,
    }
});

The solution to that issue is flexShrink: 1.

<View
    style={{ flexDirection: 'row' }}
> 
   <Text style={{ flexShrink: 1 }}>
       Really really long text...
   </Text>
</View>

Depending on your set up, you may also also need to add flexShrink: 1 to the <View>'s parent as well, to get this to work, so play with that and you'll make it.

The solution was discovered by Adam Pietrasiak in this thread.

I found solution from below link.

[Text] Text doesn't wrap #1438

<View style={{flexDirection:'row'}}> 
   <Text style={{flex: 1, flexWrap: 'wrap'}}> You miss fdddddd dddddddd 
     You miss fdd
   </Text>
</View>

As @sudoPlz mentioned in comments it works with flexShrink: 1 updating this answer.
