toJson method

Map<String, Object> toJson()

JSON shape: zero entries are omitted so sweep output stays compact.

Implementation

Map<String, Object> toJson() => {
      'phases': {
        for (final p in PdfPerfPhase.values)
          if (phaseCalls[p.index] != 0)
            p.name: {'us': phaseUs[p.index], 'calls': phaseCalls[p.index]},
      },
      'counts': {
        for (final c in PdfPerfCount.values)
          if (counts[c.index] != 0) c.name: counts[c.index],
      },
      'events': {
        for (final e in PdfPerfEvent.values)
          if (events[e.index] != 0) e.name: events[e.index],
      },
    };
