控件BrnExpandableGroup的backgroundColor设定无效

[RalghRao]

您好! 我不确定是不是因为我个人失误还是控件的问题导致背景色设定失效,如果是因为我个人原因导致的那很抱歉打扰了。
以下是我的代码：

return Scaffold(
      appBar: AppBar(title: Text(title)),
      body: const Center(
        child: Text('Home'),
      ),
      drawer: Drawer(
        // Add a ListView to the drawer. This ensures the user can scroll
        // through the options in the drawer if there isn't enough vertical
        // space to fit everything.
        backgroundColor: Colors.red,
        child: ListView(
          // Important: Remove any padding from the ListView.
          padding: EdgeInsets.zero,
          children: [
            const DrawerHeader(
              decoration: BoxDecoration(
                color: Colors.black,
                image: DecorationImage(
                  image: ExactAssetImage(
                      'images/logo_technology_financial.png'),
                  fit: BoxFit.fitWidth,
                ),
              ),
              child: Text(''),
            ),
           BrnExpandableGroup(
              title: "Dashboards",
              backgroundColor: const Color.fromARGB(255, 51, 51, 51),
              children: [
                ListTile(
                  title: const Text('Item 1'),
                  textColor: Colors.white,
                  contentPadding: const EdgeInsets.symmetric(horizontal: 32.0),
                  hoverColor: const Color.fromARGB(50, 255, 255, 255),
                  selectedColor: WitechfinThemeUtils.primary,
                  selectedTileColor: Colors.black,
                  onTap: () {
                    Navigator.pop(context);
                  },
                ),
                ListTile(
                  title: const Text('Item 2'),
                  textColor: Colors.white,
                  contentPadding: const EdgeInsets.symmetric(horizontal: 32.0),
                  hoverColor: const Color.fromARGB(50, 255, 255, 255),
                  selectedColor: WitechfinThemeUtils.primary,
                  selectedTileColor: Colors.black,
                  onTap: () {
                    Navigator.pop(context);
                  },
                ),
              ],
            ),
           BrnExpandableGroup(
              title: "Cost Management",
              backgroundColor: const Color.fromARGB(255, 51, 51, 51),
              children: [
                ListTile(
                  title: const Text('Cost Report'),
                  textColor: Colors.white,
                  contentPadding: const EdgeInsets.symmetric(horizontal: 32.0),
                  hoverColor: const Color.fromARGB(50, 255, 255, 255),
                  selectedColor: WitechfinThemeUtils.primary,
                  selectedTileColor: Colors.black,
                  onTap: () {
                    Navigator.pop(context);
                  },
                ),
                ListTile(
                  title: const Text('Cost Optimization'),
                  textColor: Colors.white,
                  contentPadding: const EdgeInsets.symmetric(horizontal: 32.0),
                  hoverColor: const Color.fromARGB(50, 255, 255, 255),
                  selectedColor: WitechfinThemeUtils.primary,
                  selectedTileColor: Colors.black,
                  onTap: () {
                    Navigator.pop(context);
                  },
                ),
              ],
            ),
          ],
        ),
      ),
    );

以下是我运行后的结果:

Bruno的版本是2.2.0

----补充----
机型是Windows的Edge
Flutter SDK是flutter_windows_3.0.3-stable
