SPResponsiveSizedBox class

A SizedBox whose width and height can change by viewport breakpoint.

Values are automatically resolved using the current viewport width. Application code does not need to read MediaQuery or manually call SPResponsiveValue.resolve.

Example:

SPResponsiveSizedBox(
  height: const SPResponsiveValue<double?>(
    base: null,
    lg: 350,
  ),
  child: chart,
)

A resolved null width or height behaves exactly like a null width or height on Flutter's native SizedBox.
