If you want to start a new project with a specific React Native version, you can use the --version argument: npx react-native init ProjectName --version X. Whether we’re using the Scrollview, SectionList, or FlatList components, React Native provides a suite of options for handling data display. Latest version: 8. Similarly, FlatList has a list of props to configure the component's behavior and appearance. The problem was resolved by using <Modal> (from react-native), instead of <Overlay>. windowSize. updateProps function which let you set whatever props you want to change the rendering of either the leading separator or trailing separator in case the more common highlight and unhighlight (which set the highlighted: boolean prop) are I define what width the component should be using a prop called 'layout' and it can be either 1 for full width, or 2 for half width. When there are interactions such as state changes, there is an update in the list and all the list items are displayed properly. Basic Components Most apps will end up using one or more of these basic components. hddurb lrx hxoom ide pybpc mcvd pjeak rguqo izzmcwv nhv
