debugEnhancePaintTimelineArguments top-level property Null safety
This flag will only add Timeline event arguments for debug builds. Additional arguments will be added for the "PAINT" timeline event and for all RenderObject paint Timeline events, which are the Timeline events that are added when debugProfilePaintsEnabled is true. The debugging information that will be added in trace arguments includes stats around RenderObject dirty states and RenderObject diagnostic information (i.e. RenderObject properties).
