使用useState更新变量时，模态打开和关闭

Question

每当我的应用程序打开一个模态并且尝试使用useState更新变量时，模态都会单独打开和关闭，在我的模态中有一个Switch，当我更改值时，它必须更改一个变量，但是碰巧这个变量我需要使用useState进行更改。

我的代码

    const OverLay = ()=> {

        return(

            <Overlay animated={true}
                     animationType={"fade"}
                     statusBarTranslucent={true}
                     isVisible={over}
                     hardwareAccelerated={true}
                     onBackdropPress={()=>setOver(false)}
                     overlayStyle={{width:"80%",padding:20}}>
                     
                    <Text style={{fontWeight:"bold", alignSelf:"center", fontSize:20, marginBottom:20}}>A impressão digital</Text>
                    <Text style={{fontSize:17}}>A impressão digital permite-te saltar o PIN e desbloquer o App com a tua impressão digital. A impressão digital só funciona caso
                        o teu smartphone suporte ou configuraste.
                    </Text>
                    <Switch
                        trackColor={{ false: "#ddd", true: Cores.primary }}
                        style={{alignSelf:"center", marginTop:10,marginBottom:20}}
                        thumbColor={isEnabled ? Cores.primary : "#ddd"}
                        ios_backgroundColor="#3e3e3e"
                        onValueChange={toggleSwitch}
                        value={isEnabled}
                    />
                        <Button
                            title="Fechar"
                            onPress={()=>{

                                setOver(false);

                            }}
                            buttonStyle={{borderColor:Cores.primary}}
                            titleStyle={{color:Cores.primary}}
                            type="outline"
                        />
            </Overlay>
        );

    }
