BreakpointValue<T> class

A responsive value that adapts dynamically dinamically to relative width screen breakpoints

final cellCount = BreakpointValue(xs: 1, s: 2, sm: 4, lg: 20);

This class is not usually used directly and if you are using Layout, it is recommended to use the context.layout.value(xs: 1, s: 2, sm: 4, lg: 20); to get directly the responsive value.

Calculating the responsive values is usually done by this library automatically but it can also be calculated with the following methods: To get the value for a given breakpoint use the method resolveForBreakpoint. If there is a Layout inside the widget you can also use resolve(context) that will automatically calulate the value for the container width provided by the closest Layout inside the upper widget tree from the context referenced provided as param.
