prismTestSizes top-level constant

Map<String, Size> const prismTestSizes

Sizes worth testing any adaptive component at.

These are not arbitrary: phone is the narrowest layout most apps support, tablet straddles the compact/medium boundary, and desktop is where two-pane layouts and extended navigation rails appear.

Implementation

const prismTestSizes = <String, Size>{
  'phone': Size(320, 568),
  'tablet': Size(834, 1112),
  'desktop': Size(1440, 900),
};
