Peek constructor

const Peek({ double peek = 0, double peekRatio = 1, AlignmentGeometry peekAlignment = Alignment.center, })

🔲 Peek

A 🌟 Surface may be provided a 🔲 Peek to define several attributes about the shared space at the adjacent edge of 📚 SurfaceLayer.BASE and 📚 SurfaceLayer.MATERIAL.

• It may be considered to function like a border for the Surface.child content.
  • Note that Surface does not currently support actual Borders.
  • To give a border to a Surface, provide a Surface as a child to a DecoratedBox or Container.

Implementation

const Peek({
  this.peek = 0,
  this.peekRatio = 1,
  this.peekAlignment = Alignment.center,
}) : assert(peek >= 0, '[Peek] > Provide a non-negative `peek`.');
