ListView or ListView.builder, which one to use and how to use them?

Well, many times in your Flutter journey, you’ll need to use lists. I

f you need to use a really big and huge list, ListView.builder() is your friend!

Not only will it make your app perform better, it will remarkably shorten the amount of code you’ll need.

Now the regular ListView is also useful, of course. But only for short/small predictable lists.

If you don’t know in advance how many items a list will have, always go with a ListView.builder, as it will only render what is visible in the viewport, making the entire process much more optimal. Thanks Flutter team!
