capture method

@override Map<String, Object?> capture()

Every part's state, in registration order, as one value restore takes back: flutter3d_sim's Snapshot, whose data holds plain values only.

Implementation

@override
Map<String, Object?> capture() => <String, Object?>{
  for (final part in _parts)
    part.id: <String, Object?>{
      'version': part.version,
      'data': part.capture(),
    },
};
