What methods would you use to optimize the application's performance if you encounter a problem of low efficiency?

To optimize the performance of a Flutter application when efficiency is low, the following methods can be used:

• Performance profiling with Flutter DevTools to identify bottlenecks.
• Minimizing widget rebuilds — use const constructors, shouldRebuild in CustomPainter, or RepaintBoundary.
• Using efficient lists — for example, ListView.builder instead of ListView for lazy loading of items.
• Optimizing state management — apply suitable state managers (Provider, Bloc) to update only necessary parts of the UI.
• Asynchronous data loading and caching to reduce delays.
• Avoid heavy operations on the main thread — move them to isolates.

Example of using ListView.builder:

ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) {
    return ListTile(title: Text(items[index]));
  },
)
