Common Flutter Errors & Rules (from evanca/flutter-ai-rules)

1. RenderFlex overflowed: check if a Row or Column contains unconstrained widgets. Fix by wrapping children in Flexible, Expanded, or by setting constraints.
2. Vertical viewport was given unbounded height: ensure ListView or similar scrollable widgets inside a Column have a bounded height (e.g., wrap with Expanded or SizedBox).
3. An InputDecorator...cannot have an unbounded width: constrain the width of widgets like TextField using Expanded, SizedBox, or by placing them in a parent with width constraints.
4. setState called during build: do not call setState or showDialog directly inside the build method. Trigger dialogs or state changes in response to user actions or after the build completes (e.g., using addPostFrameCallback).
5. The ScrollController is attached to multiple scroll views: make sure each ScrollController is only attached to a single scrollable widget at a time.
6. RenderBox was not laid out: check for missing or unbounded constraints in your widget tree. This is often caused by using widgets like ListView or Column without proper size constraints.
