This video explains Flutter's layout algorithm, which governs how widgets are sized and positioned within your app. Discover the core three-part rule: constraints go down, sizes go up, and the parent sets the position. We demonstrate how parent and child widgets communicate these rules, from simple elements to complex flex boxes, helping you understand how to debug common layout errors like unbounded width or height.
