我是一个新的typescript和转换我的jsx到tsx文件。我如何定义一个redux调度为我的onPress属性的类型？我尝试使用“函数”和“AppDispatch”。提前感谢

import { AppDispatch } from "../redux/store"

interface ItemProps {
    item: Custom_date, 
    onPress: AppDispatch, //What should I put here?
    backgroundColor: any,
    textColor: any
}

const Item = ({ item, onPress, backgroundColor, textColor }: ItemProps) => (
    <TouchableOpacity onPress={onPress} style={[styles.item, backgroundColor]}>
        <Text style={[styles.dateTitle, textColor]}>{item.title}</Text>
    </TouchableOpacity>
);

export const DateHeader = () => {
    const { date } = useSelector((store: RootState) => store.nutrition)
    const dispatch = useDispatch()
    const renderItem = ({ item }) => {
        const backgroundColor = item.id === date.id ? "#033F40" : "#BDF0CC";
        const color = item.id === date.id ? '#BDF0CC' : '#033F40';

        return (
            <Item
                item={item}
                onPress={() => dispatch(setDate(item))}
                backgroundColor={{ backgroundColor }}
                textColor={{ color }}
            />
        );
    }

    return (<>
        <FlatList {props} />
    </>)
}
