SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Flutter developers frequently encounter cryptic layout exceptions such as "RenderFlex overflowed", "Vertical viewport was given unbounded height", and "Incorrect use of ParentData widget". This Skill provides a systematic diagnostic workflow to identify the root constraint violation and apply the correct widget-level fix. ## Core Features & Use Cases - Error Signature Diagnostics: Maps common Flutter layout exceptions (unbounded height, unbounded width, RenderFlex overflow, ParentData misuse) to their underlying constraint causes. - Step-by-Step Resolution Checklist: Guides you from capturing the exception in debug mode through applying the fix and verifying with hot reload. - Concrete Code Examples: Provides before-and-after Dart snippets, such as wrapping a ListView in Expanded inside a Column, or a TextField in Expanded inside a Row. - Use Case: Your app crashes with "Vertical viewport was given unbounded height" after adding a ListView inside a Column. The Skill identifies the unbounded constraint and instructs you to wrap the ListView in an Expanded widget. ## Quick Start Ask the AI to fix the "RenderFlex overflowed" or "unbounded height" layout error in your Flutter widget tree using this Skill.

FAQPage Schema
How do I fix "Vertical viewport was given unbounded height" in Flutter?

This error occurs when a scrollable widget like ListView or GridView sits inside an unconstrained vertical parent such as a Column. Wrap the scrollable child in an Expanded widget to consume remaining space, or use a SizedBox to give it an absolute height constraint.

How to fix RenderFlex overflowed error in Flutter Row or Column?

A RenderFlex overflow happens when a child requests more space than the parent allocates. Wrap the overflowing child in Expanded to force it to fit the available space, or in Flexible to allow it to shrink below the allocated size.

Why does my TextField throw an unbounded width error inside a Row?

A TextField or TextFormField inside a Row receives infinite horizontal space and cannot determine its width, triggering the InputDecorator unbounded width error. Wrap the text field in an Expanded or Flexible widget to constrain its width.

What causes "Incorrect use of ParentData widget" in Flutter?

This error occurs when a ParentDataWidget is not a direct descendant of its required ancestor. Ensure Expanded and Flexible are direct children of Row, Column, or Flex, and that Positioned is a direct child of Stack.

Should I worry about "RenderBox was not laid out" errors?

No, this is a cascading side-effect error rather than the root cause. Ignore it and look further up the stack trace for the primary constraint violation, which is usually an unbounded height or width error.
