// 1. const: const Text('Title') vs Text('Title')

// 2. Narrow BlocBuilder: Scaffold(body: BlocBuilder(...)) 
//    vs BlocBuilder(builder: (ctx, state) => Scaffold(...))

// 3. buildWhen: buildWhen: (prev, curr) => prev.data != curr.data

// 4. ListView.builder vs ListView(children: [])

// 5. Keys: key: ValueKey(items[i].id)

// 6. Batch API:
// ❌ for (item in items) await api.fetch(item.id);
// ✅ await Future.wait(items.map((i) => api.fetch(i.id)));
