Just had one of those ‘reinventing the wheel’ moments in Flutter: 🤯 Did you know that Spacer is literally just an Expanded with a SizedBox.shrink as its child? That’s it. I never thought about how simple its implementation could be until I checked the source code.

And Center() :P

Great catch! The Center widget is basically just an Align with alignment: Alignment.center by default. Simple but effective, just like Spacer. Love how Flutter keeps things minimal!

Essentially, Spacer uses Expanded to occupy flexible space in a Row, Column, or Flex, and the SizedBox.shrink ensures it doesn’t take up any visual space. Simple and brilliant.

I’m amazed by how much you can achieve in Flutter by combining basic widgets. It’s like the entire framework is designed to encourage creativity with minimal building blocks.

If you already knew this, just pretend you didn’t and let me enjoy my 'discovery moment' 😅😂 What about you? Are there other widgets with equally simple implementations that I’m overlooking? 👀
