find<
- @override
override
Returns the value of S that corresponds to the point described by
regionOffset.
Returns null if no matching region is found.
The main way for a value to be assigned here is by pushing an AnnotatedRegionLayer into the layer tree.
See also:
- AnnotatedRegionLayer, for placing values in the layer tree.
Implementation
@override
S find<S>(Offset regionOffset) {
Layer current = lastChild;
while (current != null) {
final Object value = current.find<S>(regionOffset);
if (value != null) {
return value;
}
current = current.previousSibling;
}
return null;
}
