PanResponder 更改 Card Y 值和移出屏幕的问题

Question

I'm new to react-native animation API and PanResponder API.
I want to create google maps clone UI and animations of card which is show after results.
I want to create card and when user swipe up, the card you reach to top of screen and when user swipe down, the card should resize to original position.
Demo of Google Maps that i want to achieve

I have implemented some of code for that, but i am facing problem like card is moving out of screen in top direction (swiping up after card is reach to top position). Sometimes, swipe down works but not always.

if you wanna make bottomsheet then you can use react-native-bottomsheet-reanimated

yarn add react-native-bottomsheet-reanimated

import React, { useEffect, useState } from "react";
import {
  SafeAreaView,
  View,
  Text,
  Dimensions,
  PanResponder,
  Animated,
  StyleSheet
} from "react-native";
import { Searchbar, FAB } from "react-native-paper";
import MapView from "react-native-maps";
import * as Location from "expo-location";
import BottomSheet from "react-native-bottomsheet-reanimated";



const SCREEN_HEIGHT = Dimensions.get("window").height;
const SCREEN_WIDTH = Dimensions.get("window").width;

const App = () => {
  

  const [latitute, setLatitute] = useState(0);
  const [longitute, setLongitute] = useState(0);
  const [isLoading, setIsLoading] = useState(true);


  const pan = useState(
    new Animated.ValueXY({ x: 0, y: SCREEN_HEIGHT - 200 })
  )[0];

  useEffect(() => {
    (async () => {
      let { status } = await Location.requestPermissionsAsync();

      let location = await Location.getCurrentPositionAsync({});
      console.log(location);
      setLatitute(location.coords.latitude);
      setLongitute(location.coords.longitude);
      setIsLoading(false);
    })();
  }, []);

  return (
    <SafeAreaView
      style={{
        display: "flex",
        flex: 1,

            }}
            icon="plus"
            onPress={() => console.log("Pressed")}
          />

          <BottomSheet
