In mobile app development, a acts as a container—similar to a in standard web development. It is the fundamental building block for securing, grouping, and styling elements on a user's screen.
Standard linear layouts place elements one after another. Nesting allows you to mix horizontal and vertical alignments on a single screen.
export const styles = StyleSheet.create( container: flex: 1, justifyContent: 'center', alignItems: 'center', , viewOne: width: 250, height: 250, backgroundColor: 'powderblue', justifyContent: 'center', // To center the inner View alignItems: 'center', , viewTwo: width: 150, height: 150, backgroundColor: 'skyblue', justifyContent: 'center', alignItems: 'center', , viewThree: width: 75, height: 75, backgroundColor: 'steelblue', justifyContent: 'center', alignItems: 'center', , );
