如何在底部导航中换行

我正在尝试构建一个 Flutter 应用程序，我想在其中使用底部导航栏。但是在项目长度更长的底部导航项目上，文本不会换行。我想将文本换行到下一行。

以下是正在发生的事情的图像：

以下是代码：

class HomeScreen extends StatefulWidget {
@override
  _HomeScreenState createState() => _HomeScreenState(imageurl, name, email);
}

class _HomeScreenState extends State<HomeScreen> {
@override
  Widget build(BuildContext context) {
    // TODO: implement build
    return Scaffold(
bottomNavigationBar: Theme(
        data: Theme.of(context).copyWith(
            // sets the background color of the `BottomNavigationBar`
            canvasColor: Colors.white,
            // sets the active color of the `BottomNavigationBar` if `Brightness` is light
            primaryColor: Colors.red,
            textTheme: Theme.of(context)
                .textTheme
                .copyWith(caption: new TextStyle(color: Colors.yellow))),
        child: SizedBox(
          height: 90,
          child: Column(
            mainAxisSize: MainAxisSize.min,
            children: [
              BottomNavigationBar(
                selectedItemColor: Colors.orange,
                type: BottomNavigationBarType.fixed,
                unselectedFontSize: 12,
                elevation: 2,
                currentIndex: 2, // this will be set when a new tab is tapped
                items: [
                  BottomNavigationBarItem(
                    icon: new Icon(
                      Icons.home_outlined,
                      color: Colors.black,
                    ),
                    title: Flexible(
                      child: new Text(

                  ),
                  BottomNavigationBarItem(
                    icon: new Icon(
                      Icons.star_border,
                      color: Colors.black,

                          ),
                        ),
                      )),
                  BottomNavigationBarItem(
                      icon: Icon(

                          ),
                        ),
                      ))
                ],
              ),
            ],
          ),
        ),
      ),
);
}
}

有人可以帮助我如何在下一行中显示 ... 文本吗？
