Reactnative Typescript：onPress 类型

我刚刚将react-native 项目移植到typescript，并对作为props 的函数提出了一个问题

我路过:

<DisplayCardsWithLikes
data={testData}
likes={500}
onPress={() => this.props.navigation.navigate("CardDetailScreen")}
/>

到

type Props = {
  onPress: Function
}


const FloatingActionBut到nSimple = (props:Props) => {
  const {onPress} = props
  return (
    <View style={styles.containerFab}>
      <TouchableOpacity style={styles.fab} onPress={onPress}>
        <Icon name="plus" size={16} color={"white"} />
      </TouchableOpacity>
    </View>
  );
};

错误:

Error, caused by child onPress:
o overload matches this call.
  Overload 1 of 2, '(props: Readonly<TouchableOpacityProps>): TouchableOpacity', gave the following error.
    Type 'Function' is not assignable 到 type '(event: GestureResponderEvent) => void'.
      Type 'Function' provides no match for the signature '(event: GestureResponderEvent): void'.
  Overload 2 of 2, '(props: TouchableOpacityProps, context?: any): TouchableOpacity', gave the following error.
    Type 'Function' is not assignable 到 type '(event: GestureResponderEvent) => void'.ts(2769)
index.d.ts(5125, 5): The expected type comes from property 'onPress' which is declared here on type 'IntrinsicAttributes & IntrinsicClassAttributes<TouchableOpacity> & Readonly<TouchableOpacityProps> & Readonly<...>'
index.d.ts(5125, 5): The expected type comes from property 'onPress' which is declared here on type 'IntrinsicAttributes & IntrinsicClassAttributes<TouchableOpacity> & Readonly<TouchableOpacityProps> & Readonly<...>'

总结:

没什么疯狂的，但如果我把onPress定义为一个函数，它会显示一个错误，所以显然这不是正确的类型.你知道这个onPress功能是哪种类型的吗？

谢谢！
