Answer 1

The Material widget is responsible for:

• Clipping: If clipBehavior is not Clip.none , Material clips its widget sub-tree to the shape specified by shape , type , and borderRadius . By default, clipBehavior is
  Clip.none for performance considerations.

• Elevation: Material elevates its widget sub-tree on the Z-axis by elevation pixels, and draws the appropriate shadow.

• Ink effects: Material shows ink effects implemented by InkFeatures like InkSplash and InkHighlight below its children.
