ResponsiveAspectRatio class
A widget that adapts its layout based on the aspect ratio of its constraints.
This widget takes a list of aspect ratios and a corresponding list of builders. Each builder is used when the aspect ratio of the constraints is less than or equal to the corresponding aspect ratio in the list. If none of the aspect ratios match, the last builder in the list is used.
