My Favorite Flutter Widget (and Why It Saved Me Time)

When I started working with Flutter, I was surprised by how much time some widgets can save if you use them the right way.

One of my favorite widgets is ListView.builder.

Instead of hardcoding multiple widgets in a Column, you can let Flutter build items on-demand. This helps with performance, especially if you’re displaying a lot of data.

ListView.builder(
itemCount: items.length,
itemBuilder: (context, index) {
return ListTile(
title: Text(items[index]),
);
},
)

It might sound basic, but I’ve seen beginners overlook this and struggle with performance issues.

🔑 Tip: If your list is short and won’t grow, you can still use ListView with children directly. But when you expect scalability, ListView.builder is your best friend.
