frames property

Map<String, ({FrameRef? base, FrameRef? head})> frames
final

Each step's two frames, by the id its ComparedItem carries.

Beside the items rather than on them: a preview's shots are cache keys and these are paths, and one field meaning two different kinds of thing is how a reader ends up opening the wrong one.

Implementation

final Map<String, ({FrameRef? base, FrameRef? head})> frames;
