我正在尝试创建一个登录表单，但出现此错误。

export default function LoginScreen(props) {
        const [Submit, setSubmit] = React.useState('')
        const windowWidth = Dimensions.get('window').width
        const windowHeight = Dimensions.get('window').height
        const [valuePass, setValuePass] = React.useState('')
        const [valueUsername, setValueUsername] = React.useState('')
        const [secureTextEntry, setSecureTextEntry] = React.useState(true)
    
        const toggleSecureEntry = () => {
            setSecureTextEntry(!secureTextEntry)
        }
        const AlertIcon = (props) => <Icon {...props} name='alert-circle-outline' />
        const renderIcon = (props) => (
            <TouchableWithoutFeedback onPress={toggleSecureEntry}>
                <Icon {...props} name={secureTextEntry ? 'eye-off' : 'eye'} />
            </TouchableWithoutFeedback>
        )
    
        return (
            <View>
                <Text>Login</Text>
                <Input
                    placeholder='Username'
                    value={valueUsername}
                    style={{ width: windowWidth - 50, borderRadius: 16 }}
                    onChangeText={(nextValue) => setValueUsername(nextValue)}
                    size='large'
                />
                <View style={{ height: 15 }}></View>
                <Input
                    style={{ width: windowWidth - 50, borderRadius: 16 }}
                    size='large'
                    value={valuePass}
                    placeholder='Password'
                    caption='Should contain at least 8 symbols'
                    accessoryRight={renderIcon}
                    captionIcon={AlertIcon}
                    secureTextEntry={secureTextEntry}
                    onChangeText={(nextValue) => setValuePass(nextValue)}
                />
                <View style={{ marginTop: 25 }}>
                    <Button
                        style={{ borderRadius: 15 }}
                        onPress={setSubmit(true)}
                        size='large'
                    >
                        Submit
                    </Button>
                </View>
            </View>
        )
    }

谁能解释为什么会发生这个错误？

我是本机react的新手。

忽略这个（只是为了增加音量）==我必须添加一些无用的句子，因为 StackOverflow 给了我'It looks like your post is mostly code; please add some more details.'（对这个 stackoverflow 错误感到很沮丧）
