Can you share an example of the most complex tasks you faced recently?

One of the complex tasks in Flutter was optimizing the application's performance with a large number of widgets and animations. For example, RepaintBoundary was used to limit repainting, and lazy loading of data and widgets was implemented to reduce rendering load.

Another example is integrating with native platform APIs via platform channels, where it was necessary to handle asynchronous calls and errors correctly to avoid hangs and crashes.

// Example of using RepaintBoundary
RepaintBoundary(
  child: CustomPaint(
    painter: MyCustomPainter(),
  ),
)
