To create a list in React Native where each row displays an image of a ticket, you can follow the steps below:

  1. First, import the necessary components from React Native:
import { View, FlatList, Image } from 'react-native';
  1. Set up the data for the list. You can create an array of objects representing each ticket, with an image source for each ticket:
const ticketData = [
  {
    id: 1,
    imageSrc: require('./ticket1.png'),
  },
  {
    id: 2,
    imageSrc: require('./ticket2.png'),
  },
  // ... add more tickets here
];
  1. Create a component to render each row of the list. This component will be passed the data for a single ticket and return a view displaying an image:
const TicketItem = ({ ticket }) => (
  <View>
    <Image source={ticket.imageSrc} />
  </View>
);
  1. Add the FlatList component to your parent component and pass it the ticket data:
const App = () => (
  <View>
    <FlatList
      data={ticketData}
      renderItem={({ item }) => <TicketItem ticket={item} />}
      keyExtractor={(item) => item.id.toString()}
    />
  </View>
);

In this code snippet, we pass the ticketData array to the data prop of the FlatList, and specify a renderItem function to render each row of the list. We also use the keyExtractor prop to extract a unique key for each item, which is necessary for React to efficiently update the list when it changes.

By following these steps, you can create a list in React Native where each row displays an image of a ticket.
