get rid of border in Card Component React native element - react-native

Question

In the Card Component for react native elements
I'm trying to get rid of the border by setting the border to 0 and borderColor to transparent but there's still a gray outline
<Card
containerStyle={{borderWidth: 0, borderColor: 'transparent', elevation: 0}}
title='HELLO WORLD'
image={require('../images/pic2.jpg')}>
<Text style={{marginBottom: 10}}>
The idea with React Native Elements is more about component structure than actual design.
</Text>
</Card>
Thought it might have been box shadow, but that's not it either

Answer 1

I've got the same issue, and I've found that border appears because the Card element has an elevation default setted to 1
You can override this (for android) :
<Card containerStyle={{elevation:0, backgroundColor:#123}}/>
and in IOS:
const styles = {
container: {
shadowColor: 'rgba(0,0,0, .2)',
shadowOffset: { height: 0, width: 0 },
shadowOpacity: 0, //default is 1
shadowRadius: 0//default is 1
}
}
<Card containerStyle={styles.container} />

Answer 2

Its late but it seems that a lot of people still searching for the Answer.
React Native Elements by default have set both borderWidth and shadow Props, so in order to remove border completely you need to remove both Border and Shadow.
<Card containerStyle={styles.cardCnt}>
<Text>Content</Text>
</Card>
const styles = {
cardCnt: {
borderWidth: 0, // Remove Border
shadowColor: 'rgba(0,0,0, 0.0)', // Remove Shadow for iOS
shadowOffset: { height: 0, width: 0 },
shadowOpacity: 0,
shadowRadius: 0,
elevation: 0 // Remove Shadow for Android
}
};

It looks like react native elements' Card component has a grey border in all of the examples I've seen. I'd suggest building your own card component. Start with something like this and then style it however you want. This one has a bit of shadow which you can turn off by passing it a noShadow prop.
import React from 'react';
import { View, StyleSheet } from 'react-native';
const Card = (props) => {
let shadowStyle = {
shadowColor: COLORS.grey3,
shadowOffset: { width: 0, height: 0 },
shadowOpacity: .5,
shadowRadius: 12,
elevation: 1,
}
if (props.noShadow) {
shadowStyle = {}
}
return (
<View style={[styles.containerStyle, props.style, shadowStyle]}>
{props.children}
</View>
);
};
const styles = StyleSheet.create({
containerStyle: {
padding: 10,
marginHorizontal: 10,
backgroundColor: COLORS.white,
borderRadius: 3,
}
})
export { Card };
Then when you want to use it just
import { Card } from './yourCustomCardFile'
Then in your render method
<Card>
<Text>Any content you want to include on the card</Text>
<Text>More content that you want on the card</Text>
</Card>

Answer 4

set elevation to 0 and borderColor to white like this
<Card containerStyle={{ elevation: 0, borderColor: "white" }}>
