The RenderObject Level

Widgets are just blueprints. The real work happens in RenderObject.

The Hierarchy

StatelessWidget -> Element -> RenderObject.

Why Build One?

When you need a custom scrolling effect or a layout that doesn't follow standard rules, RenderObject gives you direct access to the paint and performLayout methods.

Practice: Create a RenderShiftedBox that offsets its child based on the device's gyroscope data.
