如何在顫動中將小部件與右下角對齊

這是我想要的輸出。

但我無法使用定位的小部件對齊它。

這是我的輸出。我嘗試了這個職位，但它不起作用，我怎么能做到這一點。這是我的代碼

Scaffold(
      backgroundColor: bgColor,
      body: Center(
          child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          Padding(
            padding: const EdgeInsets.all(28.0),
            child: Container(
              height: 190,
              width: double.infinity,
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(25),
                color: containerColor,
              ),
              child: Row(
                // mainAxisAlignment: MainAxisAlignment.spaceBetween,
                children: [
                  Padding(
                    padding: const EdgeInsets.all(28.0),
                    child: Container(
                      height: 130,
                      width: 140,
                      decoration: BoxDecoration(
                          color: bgColor,
                          borderRadius: BorderRadius.circular(20)),
                    ),
                  ),
                  Container(
                    height: 30,
                    width: 60,
                    decoration: BoxDecoration(
                      color: themeBlueColor,
                      borderRadius: BorderRadius.circular(10),
                    ),
                  ),
                ],
              ),
            ),
          ),
        ],
      )),
    );

我如何做到這一點？
