React Native components ScrollView and FlatList are utilized in React Native applications to render multiple items. The dynamic display of components is a common requirement in mobile applications.
ScrollView is suitable when the content exceeds the available space within a single view and necessitates scrollbar options. However, one disadvantage of ScrollView occurs when multiple components are present within the view. ScrollView renders all the components simultaneously, even if they are not currently visible on the screen. This approach becomes inefficient when dealing with lists containing hundreds to thousands of items.
In contrast, the FlatList component in React Native renders items on an as-needed basis. Therefore, it is recommended to use the FlatList component instead of ScrollView for efficiently rendering multiple items in such cases.
