Custom pagination, if implemented properly, can provide a better user experience.
Learn how to create a custom pagination solution in React Native that allows you to load data dynamically.
This typically involves fetching data from an API or database and storing it in a state variable.
Considera simple REST APIthat returns a list of books.
This function will decide what to render on the screen of the React Native app.
Here, thePAGE_SIZEconstant is used to limit the number of books fetched per page.
We use theuseEffect()hook to fetch the initial page of data when our app first runs.
Next, we define arenderItemfunction that takes an item from thebooksarray and returns aViewcontaining the book title and author.
Finally, we have passed thebooksarray to thedataprop of theFlatList, along with ourrenderItemfunction andkeyExtractor.
At that point, it should proceed to fetch and load the new data and render it.
We should also update ourcurrentPagestate to keep track of which page we’re currently on.
We created a new function calledfetchMorethat runs whenonEndReachedis fired.
Finally, we added the new necessary props to ourFlatListcomponent.
TheFlatListcomponent will now dynamically load data as the user scrolls to the end of the list.
This method gives you more flexibility and control when dealing with large amounts of data in your app.
Remember to tailor your pagination to match your app’s style and needs.
you could customize it even further to achieve the desired look and functionality.
Overall, it would definitely help you to optimize your app’s performance.
