DiffLayout class final

Random-access layout storing runs instead of one object per visible line. Constructing and expanding a large context region costs one block, while accessing an individual row takes logarithmic time.

Constructors

DiffLayout(List<FileDiff> files, {DiffMode mode = DiffMode.unified, Set<int> collapsed = const {}, Set<DiffGapId> expanded = const {}, Map<DiffGapId, GapExpansion> expansions = const {}, int contextThreshold = 0, bool expandAll = false, Set<DiffGapId> collapsedHunks = const {}, bool showHunkHeaders = false})
Indexes logical diff rows without allocating a list of every row.
