text shadow in react native

CSS text-shadow has the below syntax,

text-shadow: h-shadow v-shadow blur-radius color|none|initial|inherit;

To achieve similar effect with the css you provided you can use something like this,

// text-shadow: -1px 1px 10px rgba(0, 0, 0, 0.75)

{
  textShadowColor: 'rgba(0, 0, 0, 0.75)',
  textShadowOffset: {width: -1, height: 1},
  textShadowRadius: 10
}

I tried sir bennygenel's answer and it worked. I used it something like this...

<View>
    <Text style={styles.textWithShadow}>Hello world</Text>
</View>

.....

const styles = StyleSheet.create({
     textWithShadow:{
         textShadowColor: 'rgba(0, 0, 0, 0.75)',
         textShadowOffset: {width: -1, height: 1},
         textShadowRadius: 10
     }
});
