flutter-fix-layout-issues

Fix a RenderFlex overflow by restructuring the widget tree to enforce proper parent-child constraints. Wrapping the overflowing child in an Expanded or Flexible widget provides bounded dimensions and resolves the rendering exception.

A Flutter ListView throws an unbounded viewport error inside a Column because the vertical constraints are unbounded. Wrap the ListView in an Expanded widget to constrain its height and resolve the layout failure.

Unbounded constraint violations in Flutter UI debugging occur when widgets fail to render due to improper parent-child constraint negotiation. The parent provides infinite space, requiring layout primitives like SizedBox to establish strict boundaries.

Use Expanded to force a child to fill available space and resolve layout errors with strict boundaries. Use Flexible when the child can be smaller than available space, allowing proper constraint negotiation without forcing maximum dimensions.

The systematic workflow to resolve Flutter layout constraint violations involves diagnosing the root cause of unbounded height or width failures, then applying a checklist of fixes using Expanded, Flexible, or SizedBox widgets to restructure the tree.

Yes, this Skill works for debugging unbounded width errors in Dart by diagnosing improper parent-child constraint negotiations. It guides precise widget tree restructuring using standard Flutter layout primitives to satisfy rendering requirements.
