react-native - 来自 React-native-elements/fontAwesome 的图标未显示

Question

我正在为抽屉项目和 headerLeft 设置图标。但图标没有出现在我的 android 应用程序中。我正在使用react-native-elements库在我的代码中使用图标。图标类型是字体真棒。我已经特别提到了图标的类型。

我已经尝试了所有命令，例如react-native link并成功链接了所有库，但没有任何效果。

我希望出现图标，但根本不出现。

这是一种方法，自 2020 年 1 月 20 日起有效。

假设您已经react-native-elements安装，如果没有yarn add react-native-elements

import { Icon } from 'react-native-elements';
.
.
.

// Drawer Navigator
const DrawerNavigator = createDrawerNavigator({
  Home: {
    screen: HomeScreen,
    navigationOptions: {
      drawerIcon: (
        <Icon
          reverseColor
          name='home'
          type='font-awesome'
          size={26}
        />
      ),
    },
  }
});
