To create a horizontal divider in React Native, simply use View plus some styles.

Code:

<View 
    style={{
        borderBottomColor: '#137cbd',
        borderBottomWidth: 2,
        width: 100, 
        height: 100,
        alignSelf: 'center'
    }} 
/>

width and height are used to define the divider's size, and if the parent component already has justifyContent: 'center' and alignItems: 'center' to horizontally and vertically center the child components, alignSelf: 'center' is sufficient to center the divider itself.
