Hi
The following works for me in both Android and iOS:
import React from 'react';
import { View } from 'react-native';
import { LinearGradient } from 'expo-linear-gradient';
export default function App() {
return (
<View style={{ flex: 1 }}>
<LinearGradient
colors={['lightblue', 'black', 'lightgreen']}
start={[0.0, 0.0]}
end={[1.0, 1.0]}
style={{ flex: 1 }}
/>
</View>
);
}
