Is there a way for me to retrieve dynamic text?

I used an "IF" statement to display dynamic text - if it's null, show something, otherwise show something else. However, I am getting a blank result. What did I do wrong?

<View style={styles.rightContainer}>
    { () =>{        
        if(this.state.sicafSource.IdStatusManutencao == null){

            return(
                <View style={[{paddingHorizontal:10, marginTop:5,borderRadius:5},this.ReturnColor("Not found in API","ACTIVE")]}>
                        <Text style={[{ textAlign: 'right' }, styles.swipeCardRightTextS]}>
                                No information available 
                        </Text>
                </View>
            );

    }
    else{

        return(
            <View style={[{paddingHorizontal:10, marginTop:5,borderRadius:5},this.ReturnColor("Not found in API","ACTIVE")]}>
                <Text style={[{ textAlign: 'right' }, styles.swipeCardRightTextS]}>
                    API response is true 
                </Text>
            </View>          

        );
    }
}
    }
</View>

Answer №1

To incorporate conditional rendering in JSX, it is essential to utilize the ternary operator. The content enclosed within curly braces {} must be an expression that yields a value as opposed to statements. More information on expressions versus statements can be found at .

{this.state.exampleVariable == null ? (
    <div>Display this when condition is true</div>
) : (
    <div>Display this when condition is false</div>
)

To resolve this issue, you can execute your anonymous function to ensure the if statement is assessed:

() => {
  // ...
} () // make sure to include these

However, a more concise approach is to use ternary operators or boolean operators. Instead of

if (X) {
  Y;
} else {
  Z;
}

You have the option to either

X ? Y : Z

or

X && Y || Z
