What is semantic label in Flutter?

container : Whether this node introduces a new semantic node (SemanticsNode) in the semantic tree . It can not be separated or merged by upper layer semantics, that is, independent. explicitChildNodes : The default is false, indicating whether to force the display of the semantic information of the child widget.

ExcludeSemantics class Null safety A widget that drops all the semantics of its descendants . When excluding is true, this widget (and its subtree) is excluded from the semantics tree. This can be used to hide descendant widgets that would otherwise be reported but that would only be confusing.

In Semantics, we have (among others) three useful String parameters for that: label, which is a brief description of the widget , hint, which is an explanation of the action that will occur when the widget is interacted with, and value, which provides a textual description of the widget’s state.22 Tem 2018
