I'm trying to deactivate a bottom sheet by swiping it down using useState, but that state is in another component, that is the screen that contains that bottom sheet. I

Code of bottom sheet component:

useSharedValue,

import defaultStyles from "../config/styles";
const windowHeight = Dimensions.get("window").height;
const BottomSheet = ({ children, title }) => {
const translateY = useSharedValue(0);
const context = useSharedValue({ y: 0 });
const gesture = Gesture.Pan()
.onStart(() => {
context.value = { y: translateY.value };
})
.onUpdate((event) => {
translateY.value = event.translationY + context.value.y;
translateY.value = Math.max(translateY.value, -windowHeight / 3);
})
.onEnd(() => {
if (translateY.value > -windowHeight / 4) {
translateY.value = withSpring(0, {
damping: 15,
});
} else if (translateY.value < -windowHeight / 3.5) {
translateY.value = withSpring(-windowHeight / 3, { damping: 15 });
}

translateY.value = withSpring(-windowHeight / 3, { damping: 15 });

introduction:
"Ocorrem na Madeira durante todo o ano. Muito activas e lúdicas na superfície. Muitas vezes aproximam-se curiosamente de barcos e saltam, fazem proa e enfiam a cabeça fora de água. A população desta espécie na Madeira é constituída por dois ecótipos; o maior, do tipo offshore pelágico e o menor, do tipo costeiro, com esta última comunidade mesmo contendo grupos residentes.",
history:
"Os golfinhos roaz-corvineiro comuns recebem o seu nome do seu focinho curto e grosso (ou rostro). São geralmente de cor cinzenta. Podem variar entre cinzento claro e quase preto no topo perto da barbatana dorsal e cinzento claro até quase branco na barriga.",

"Os golfinhos roazes dos Estados Unidos migram para cima e para baixo na costa atlântica, dirigindo-se para norte na Primavera, e novamente para sul no Outono.",

Also, when i swipe down the bottom sheet, it says like this, and it works fine in some android simulators
Image of the screen when i swipe the bottomsheet down
While it should go to the end of the screen, what am i doing wrong?
Trying a solution for the problem 1
const BottomSheet = ({ children, title , deactivateBottomSheet}) => {
const translateY = useSharedValue(0);
const context = useSharedValue({ y: 0 });
const gesture = Gesture.Pan()
.onStart(() => {
context.value = { y: translateY.value };
})
.onUpdate((event) => {
translateY.value = event.translationY + context.value.y;
translateY.value = Math.max(translateY.value, -windowHeight / 3);
})
.onEnd(() => {
if (translateY.value > -windowHeight / 4) {
translateY.value = withSpring(0, {
damping: 15,
});
deactivateBottomSheet();
} else if (translateY.value < -windowHeight / 3.5) {
translateY.value = withSpring(-windowHeight / 3, { damping: 15 });
}
});
I tried to call a function where the animation ends, that is when the translateY.value is 0, and pass it through props to the parent component, and define the function there, but the app crashed.
