isBlockingUserActions property
getter/setter pair
Whether to block pointer related user actions for the rendering subtree.
Setting this to true will prevent users from interacting with the rendering object produces this semantics configuration and its subtree through pointer-related SemanticsActions in assistive technologies.
The SemanticsNode created from this semantics configuration is still focusable by assistive technologies. Only pointer-related SemanticsActions, such as SemanticsAction.tap or its friends, are blocked.
If this semantics configuration is merged into a parent semantics node, only the SemanticsActions from this rendering object and the rendering objects in the subtree are blocked.
Implementation
bool isBlockingUserActions = false;
