flutter-smell-list-performance

What problem does it solve?

Flutter apps with large lists or grids can suffer from slow builds and janky scrolling when lists are rendered with non-builder widgets, lack of pagination, and unstable item keys.

Core Features & Use Cases

• Detect performance smells in ListView, GridView, and Sliver-based lists.
• Recommend and apply builder-based rendering (ListView.builder, SliverList) and implement stable keys.
• Use cases include long product grids, chat lists, and data-heavy lists where smooth scrolling is critical.

Quick Start

Inspect a Flutter screen with a long list, identify non-builder patterns, and convert to a builder-based approach with stable keys and optional pagination.
