What components or tools do you use to create interfaces that adapt to different screen sizes?

To create responsive interfaces in Flutter, the following components and approaches are usually used:

• MediaQuery — allows obtaining the screen size and device orientation to adjust widget sizes and layout.

• LayoutBuilder — provides size constraints from the parent widget, helping to build different layouts depending on available space.

• Flexible and Expanded — help flexibly distribute space among child widgets.

• AspectRatio — maintains a specified aspect ratio.

• OrientationBuilder — reacts to changes in screen orientation.

• Responsive frameworks and packages (e.g., flutter_screenutil, responsive_builder) — simplify the creation of responsive interfaces.

Example of using MediaQuery:

Widget build(BuildContext context) {
  var screenWidth = MediaQuery.of(context).size.width;
  if (screenWidth < 600) {
    return MobileLayout();
  } else {
    return TabletLayout();
  }
}
