React native 在react native中使用矢量图标中的预加载图标

我试着在我的Expo应用程序中使用Entypo的矢量图标中的“拇指朝上”图标。我得到一个关于它是自定义字体的错误，我需要使用font.loadAsync。我浏览了这篇文章和其他一些关于stackoverflow的文章，并根据以下内容修改了代码-

import React，{useState}来自“React”；
从“react native”导入{样式表、视图、文本}；
从“../components/AppText”导入AppText；
从“../components/Screen”导入屏幕；
从“expo”导入{AppLoading}；
从“expo字体”导入*作为字体；
从“@expo/vector icons”导入{Entypo}；
异步函数_loadAssetAsync（）{
等待承诺.all（[Font.loadAsync（Entypo.Font）]）；
}
函数安全扫描报告（props）{
const[isReady，setIsReady]=useState（false）；
如果（！isReady）{
返回(
setIsReady（真）}
onError={console.warn}
/>
);
}
否则{
让报告=(
安全进入
);
if（props.permitAccess==false）{
报告=(
拒绝访问
);
}
返回(
{报告}
);
}
}
const styles=StyleSheet.create({
容器：{
为内容辩护：“中心”，
对齐项目：“居中”，
},
报告容器：{
弹性：1，
宽度：“100%”，
为内容辩护：“中心”，
对齐项目：“居中”，
填充：8，
}
});
导出默认安全扫描报告；

然而，我仍然得到如下相同的错误。我如何使用事先加载的资产，或者资产是否未正确加载

fontFamily "entypo" is not a system font and has not been loaded through Font.loadAsync.

- If you intended to use a system font, make sure you typed the name correctly and that it is supported by your device operating system.

- If this is a custom font, be sure to load it with Font.loadAsync.
