debugDescribeChildren method Null safety
override
Returns a list of DiagnosticsNode objects describing this node's
children.
Children that are offstage should be added with style set to
DiagnosticsTreeStyle.offstage to indicate that they are offstage.
The list must not contain any null entries. If there are explicit null
children to report, consider DiagnosticsNode.message or
DiagnosticsProperty<Object> as possible DiagnosticsNode objects to
provide.
Used by toStringDeep, toDiagnosticsNode and toStringShallow.
See also:
- RenderTable.debugDescribeChildren, which provides high quality custom descriptions for its child nodes.
Implementation

List<DiagnosticsNode> debugDescribeChildren() {
return menus.map<DiagnosticsNode>((MenuItem child) => child.toDiagnosticsNode()).toList();
