linearGradientProps crashes my app
What can I do about it? I can't use the code that should work:
<Button
text="SIGNUP"
ViewComponent={require('react-native-linear-gradient').LinearGradient}
linearGradientProps={{
colors: ['red', 'pink', 'red'],
}}
/>
I get this annoyance:
console.error: "You need to pass a ViewComponent to use linearGradientProps !
Example: ViewComponent={require('react-native-linear-gradient')}"

You need to use require('react-native-linear-gradient').default.
I've updated the example on Github, my bad.
Try this instead (with RNE v1.0.0-beta3):
<Button
title="SIGNUP"
ViewComponent={require('react-native-linear-gradient').default}
linearGradientProps={{
colors: ['#FF9800', '#F44336'],
start: [1, 0],
end: [0.2, 0],
}}
/>
This should give you this result

Give something like this a try? this is their documented example on their github
import LinearGradient from 'react-native-linear-gradient';
// Within your render function
<LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']} style={styles.linearGradient}>
<Text style={styles.buttonText}>
Sign in with Facebook
</Text>
</LinearGradient>
// Later on in your styles..
var styles = StyleSheet.create({
linearGradient: {
flex: 1,
paddingLeft: 15,
paddingRight: 15,
borderRadius: 5
},
buttonText: {
fontSize: 18,
fontFamily: 'Gill Sans',
textAlign: 'center',
margin: 10,
color: '#ffffff',
backgroundColor: 'transparent',
},
});
