我在使用 Framer Motion 库时遇到问题，尤其是 AnimatePresence 过渡。我可以让它在正常情况下工作，但是当我将我的 Routes 包装在自定义实现中时，我无法让退出动画工作。

当我导航到不同的路线时，我确认在组件上使用 useEffect 挂钩正在卸载，但退出动画不是由父级 AnimatePresence 触发的。

任何帮助将不胜感激。

这是我的代码：

应用程序.ts

const App = () => {

    const auth: AuthContextState = useContext(AuthContext);
    const db: FirestoreContextProps = useContext(FirestoreContext);

    const components = {
        home: HomeScreen,
        classes: ClassScreen,
        users: UserScreen,
        login: LoginScreen
    }



    return (
        <Background>
            <Navbar/>
            <Dashboard isLoggedIn={auth.data.authenticated}>
                <AnimatedRoutes>
                    <RouteTransition path={`/home`} key={0}>
                        <HomeScreen key={0} />
                    </RouteTransition>
                    <RouteTransition path={`/classes`} key={1}>
                        <ClassScreen key={1} />
                    </RouteTransition>
                    <RouteTransition path={`/users`} key={2}>
                        <UserScreen key={2} />
                    </RouteTransition>
                    <RouteTransition path={'/login'} key={3}>
                        <LoginScreen key={3} />
                    </RouteTransition>
                    <RouteTransition exact path={'/'} key={4}>
                        <Redirect to={'/home'}/>
                    </RouteTransition>
                </AnimatedRoutes>
            </Dashboard>
        </Background>
    );
}

动画路线：

type Props = {
    exitBeforeEnter?: boolean
    initial?: boolean
}

export const AnimatedRoutes: FC<Props> = ({
    children,
    exitBeforeEnter = true,
    initial = false,
}) => {

    return (
        <AnimatePresence exitBeforeEnter={exitBeforeEnter} initial={initial}>
            <Switch>
                {children}
            </Switch>
        </AnimatePresence>
    )

}

type RouteProps = {
    key: number
    exact?: boolean
    path: string
    slide?: number
    slideUp?: number
}

export const RouteTransition: FC<RouteProps> = ({

    children,
    key,
    exact = false,
    path,
    slide= 0,
    slideUp = 0,
    ...rest

}) => {

    return (
        <Route path={path} exact={exact} {...rest}>
            <MountTransition key={key} >
                {children}
            </MountTransition>
        </Route>
    )
}

安装过渡：

type Props = {
    key: number
    slide?: number
    slideUp?: number
}


const Container = styled(motion.div)`
    display: flex;
    height: 100%;
    width: 100%;
`

export const MountTransition: FC<Props> = ({
    children,
    key,
    slide = 0,
    slideUp = 0,
}) => {
    return (
        <Container
            key={key}
            initial={{opacity: 0, x: slide, y: slideUp}}
            animate={{opacity: 1, x: 0, y: 0}}
            exit={{opacity: 0, x: slide, y: slideUp}}
            transition={{type: 'tween', duration: 2, ease: 'easeInOut'}}
        >
            {children}
        </Container>
    )
}

尝试这样的事情：

<Route
   render={({location}) => {
     return (
       <AnimatePresence exitBeforeEnter>
          <Switch location={location} key={location.key}>
             <Route .../>
             <Route .../>
             <Route .../>
           </Switch>
       </AnimatePresence>
     )
   }}
 />
