### 🚫 Avoid Using ListView with Inline Children #13

@ajaxspace

Description

@ajaxspace

Problem:
ListView is used with a fixed children list instead of a builder-based constructor:

ListView(
  children: [
    ...
  ],
);

Issues:

  • Not memory-efficient for long or dynamic lists
  • Prevents lazy rendering and virtualization
  • Reduces performance on large datasets

Recommendation:
Use ListView.builder or ListView.separated for better performance and cleaner scaling.

✅ Use ListView.builder:

ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) => buildItem(items[index]),
);

✅ Use ListView.separated when consistent spacing or dividers are needed:

ListView.separated(
  itemCount: items.length,
  itemBuilder: (context, index) => buildItem(items[index]),
  separatorBuilder: (context, index) => const SizedBox(height: 12),
);

Impact:

  • Better performance and memory usage
  • Cleaner code structure for dynamic lists
  • Easier to maintain and refactor
