getRenderObjectDiagnostics method

Future<Map<String, Object?>> getRenderObjectDiagnostics(
  1. SerializableFinder finder,
  2. {int subtreeDepth = 0,
  3. bool includeProperties = true,
  4. Duration? timeout}

Returns a JSON map of the DiagnosticsNode that is associated with the RenderObject identified by finder.

The subtreeDepth argument controls how many layers of children will be included in the result. It defaults to zero, which means that no children of the RenderObject identified by finder will be part of the result.

The includeProperties argument controls whether properties of the DiagnosticsNodes will be included in the result. It defaults to true.

RenderObjects are responsible for positioning, layout, and painting on the screen, based on the configuration from a Widget. Callers that need information about size or position should use this method.

A widget may indirectly create multiple RenderObjects, which each implement some aspect of the widget configuration. A 1:1 relationship should not be assumed.
