setIsComplexHint method

void setIsComplexHint()

Hints that the painting in the current layer is complex and would benefit from caching.

If this hint is not set, the compositor will apply its own heuristics to decide whether the current layer is complex enough to benefit from caching.

Calling this ensures a Canvas is available. Only draw calls on the current canvas will be hinted; the hint is not propagated to new canvases created after a new layer is added to the painting context (e.g. with addLayer or pushLayer).


void setIsComplexHint() {
  if (_currentLayer == null) {
  _currentLayer!.isComplexHint = true;
