How do I make text bold, italic, or underline in React Native?

问题

Surprisingly there isn't one question that groups these all together yet on Stack Overflow; there hasn't been an answer on SO for italics or underline, in fact, only this question for bold. I self-answered this quesiton below.

回答1:

<Text style={styles.bold}>I'm bold!</Text>
<Text style={styles.italic}>I'm italic!</Text>
<Text style={styles.underline}>I'm underlined!</Text>

const styles = StyleSheet.create({
    bold: {fontWeight: 'bold'},
    italic: {fontStyle: 'italic'},
    underline: {textDecorationLine: 'underline'}
})

回答2:

<View style={styles.MainContainer}>
    <Text style={styles.TextStyle}>Example of Underline Text</Text>
</View>

TextStyle: {
    textAlign: 'center',
    fontWeight: 'bold'
    fontstyle: 'italic'
    fontSize: 20,
    textDecorationLine: 'underline',
    //line-through is the trick
},

Only one line solution

<Text style={{fontStyle: 'italic', fontWeight: 'bold', textDecorationLine: 'underline'}}>Bold, Italic & Underline Text</Text>
