flutter-smell-layout-hotspots

Flutter jank often stems from expensive layout hotspots. This Skill detects anti-patterns like IntrinsicHeight or LayoutBuilder in hot paths, guiding targeted refactors to eliminate expensive rebuilds and smooth scrolling.

To fix deep Column nesting, replace heavy layouts with scrollable lists like ListView or SliverList. This Skill identifies deep widget trees and prescribes extracting reusable subtrees to reduce layout cost spikes.

Use RepaintBoundary in high-cost regions where frequent repaints cause jank. This Skill flags high-cost layout areas and recommends adding RepaintBoundary boundaries to isolate and optimize expensive rendering.

IntrinsicHeight and IntrinsicWidth cause severe performance issues in Flutter hot paths by forcing expensive layout calculations. This Skill detects these layout smells and recommends scalable replacements to eliminate jank.

The best way to refactor non-scrolling Columns is replacing them with ListView or SliverList. This Skill detects heavy layout patterns and prescribes const widgets and scrollable list replacements to keep Flutter UIs smooth.
