Summary information about a SemanticsNode object.

A semantics node might SemanticsNode.mergeAllDescendantsIntoThisNode, which means the individual fields on the semantics node don't fully describe the semantics at that node. This data structure contains the full semantics for the node.

Typically obtained from SemanticsNode.getSemanticsData.

Constructors

SemanticsData({@required int flags, @required int actions, @required String label, @required Rect rect, Matrix4 transform })

Creates a semantics data object.

Properties

actions → int

read-only
hashCode → int

read-only
label → String

A textual description of this node.

read-only
rect → Rect

Operators

operator ==(other) → bool

The equality operator.

Methods
