FlexboxContainerDsl

Marker for the context-free flexbox container DSL (Row and Column in this package). This makes sure that scope-specific functions like FlexboxScope.child can only apply to the closest receiver annotated with FlexboxContainerDsl.

Distinct from com.facebook.litho.ContainerDsl so the two DSLs do not interfere: the legacy ResourcesScope.Row { } / Column { } DSL uses @ContainerDsl (which subtypes ResourcesScope), while this DSL applies to FlexboxScope (which does NOT extend ResourcesScope) so that outer ResourcesScope extensions remain reachable inside the children block.
