performActionAt method
- Offset position,
- SemanticsAction action, [
- Object? args
Asks the SemanticsNode at the given position to perform the given action.
If the SemanticsNode has not indicated that it can perform the action, this function does nothing.
If the given action
requires arguments they need to be passed in via
the args
parameter.
Implementation
void performActionAt(Offset position, SemanticsAction action, [ Object? args ]) {
final SemanticsNode? node = rootSemanticsNode;
if (node == null) {
return;
}
final SemanticsActionHandler? handler = _getSemanticsActionHandlerForPosition(node, position, action);
if (handler != null) {
handler(args);
}
}
