Answer 1

语法错误，用这个

const CustomHeader = (props) => { 
    const {title, home} = props;
    ....
    props.navigation.goBack() 
}

或

const CustomHeader = ({title, home, navigation}) => {
   .....
   navigation.goBack() // <== No props.navigation
}

Answer 2

请在 CustomerHeder 组件中指定传递给 prop 的值。

<CustomerHeder title={"title"} isHome={"something"}/>

const CustomerHeder = (props) => {
  
  const {title, isHome} = props   


   return ...
}

你也可以试试……

const CustomerHeder = ({title , isHome}) => {
  
   


   return ...
}
