find<S> method

  1. @override
S find <S>(Offset regionOffset)
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.

    final Object untypedResult = value;
    final S typedResult = untypedResult;
    return typedResult;
