AdaptiveContainer class

A simplified declarative wrapper around ContainerQuery. It allows you to specify different widgets for different container sizes without writing if/else logic.

Example: AdaptiveContainer( xs: Icon(Icons.menu), // Show icon on very small width md: Text("Menu"), // Show text on medium width lg: Row(...), // Show full row on large width )
