Usage

Complete example

MeasuredSize(
              onChange: (Size size) {
                setState(() {
                  print(size);
                });
              },
              child: Text(
                '$_counter',
                style: Theme.of(context).textTheme.headline4,
              ),
            );

onChange will be called when the [Size] changes.

onChange will return the value ONLY once if it didn't change, and it will NOT return a value if it's equals to Size.zero
