Try using Stack and Positioned

return Container(
      child: Stack(
        children: [
          Column(
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              Expanded(
                flex: 1,
                child: Container(
                  color: Colors.blue,
                  child: Image.asset('assets/images/logo.png'),
                ), // Put FortuneWheel here instead of Container
              ),
            ],
          ),
          Positioned(
            left: 0,
            right: 0,
            bottom: 0,
            child: Container(
                height: MediaQuery.of(context).size.height / 2, // Height of the device divided by 2, so the red Container would take half of the screen.
                color: Colors.red,
            ),
          ),
        ],
      ),
    );
