带有反应导航的 Expo SDK 45 启动画面
Expo SDK 45 splash screen with react navigation
我刚刚升级到 Expo SDK 45,我收到一条警告:“expo-app-loading 已被弃用,取而代之的是 expo-splash-screen:使用 SplashScreen.preventAutoHideAsync() 和 SplashScren.hideAsync( ) 相反。https://docs.expo.dev/versions/latest/sdk/splash-screen/。所以我做了并遵循了提供的 link。
我现在遇到的问题是,在示例中,他们在根视图的 onLayOut 上调用了 onLayOutRootView。现在我正在使用 react-navigation,所以我的根视图嵌套在我的应用程序中很深。
我是否必须将这个函数向下传递到根视图,或者是否有办法将这个函数传递到我的 providers/navigationcontainer 之一?或者任何其他修复?
//imports
export default App = () => {
const [appIsReady, setAppIsReady] = useState(false);
const scheme = "dark";
useEffect(() => {
async function prepare() {
try {
// Keep the splash screen visible while we fetch resources
await SplashScreen.preventAutoHideAsync();
// Pre-load fonts, make any API calls you need to do here
await Font.loadAsync(customFonts);
} catch (e) {
console.warn(e);
} finally {
// Tell the application to render
setAppIsReady(true);
}
}
prepare();
}, []);
const onLayoutRootView = useCallback(async () => {
if (appIsReady) {
await SplashScreen.hideAsync();
}
}, [appIsReady]);
if (appIsReady) {
return (
<StripeProvider publishableKey={PUBLISHABLE_KEY}>
<ThemeProvider theme={scheme === "dark" ? darkTheme : lightTheme}>
<StatusBar barStyle={scheme === "dark" ? "light-content" : "dark-content"} />
<OrderProvider>
<CartProvider>
<FavoriteProvider>
<FirebaseProvider>
<UserProvider>
<NavigationContainer
theme={scheme === "dark" ? darkTheme : lightTheme}
ref={navigationRef}
>
<RootStackScreens on/>
</NavigationContainer>
</UserProvider>
</FirebaseProvider>
</FavoriteProvider>
</CartProvider>
</OrderProvider>
</ThemeProvider>
</StripeProvider>
);
} else {
return null;
}
};
谢谢。
您可以尝试用 flex:1
.
将所有内容包装在 View
中
像这样:
...imports...
import { View } from "react-native";
export default App = () => {
...code...
const onLayoutRootView = useCallback(async () => {
if (appIsReady) {
await SplashScreen.hideAsync();
}
}, [appIsReady]);
if (!appIsReady) {
return null;
}
return (
<View style={{ flex: 1 }} onLayout={onLayoutRootView}>
<StripeProvider publishableKey={PUBLISHABLE_KEY}>
...
</StripeProvider>
</View>
);
}
