有什么解决方法可以将BottomNavigationBarItem转换为不同的语言?
我使用Lang.getString(context,key)来访问 map (从json文件加载)以获取正确的翻译,对这样的标签(即“Home”)进行硬编码没有任何意义。我该怎么办?
PageView(
controller: pageController,
onPageChanged: _pageSwipped,
children: <Widget>[Page1()],
),
bottomNavigationBar: BottomNavigationBar(
items: const <BottomNavigationBarItem>[
BottomNavigationBarItem(
icon: Icon(Icons.list),
label: Lang.getString(context, key), // it doesn't work because it should be constant.
),
],
currentIndex: _currenIndex,
selectedItemColor: Colors.blue,
iconSize: _deviceSize.size.height * 0.046,
selectedFontSize: _deviceSize.size.height * 0.023,
unselectedItemColor: Colors.grey,
onTap: _bottomTapped,
)
最佳答案
从行中删除 const 关键字
items: const <BottomNavigationBarItem>[
......
......
]
