showNotification in react不起作用

Question

1.生命周期回调的调用。I有如下代码：

// app.js
<Admin>
   <Resource name="FooList" list={FooList} />
</Admin>

// FooList.js
class FooList extends React.Component {
     componentDidMount () {
         showNotification("foo")
     }
}

export default connect(null, {showNotification})(FooList)

在安装组件时，控制台中出现了一个错误：

 Warning: React does not recognize the `showNotification` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `shownotification` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

2.调用某些事件(例如单击).--在其他情况下--我有一些处理程序，并在其中调用showNotification。

class Foo extends React.component {
   handleClick = () => {
      showNotification('Hello, World')
   }
}

export default connect(null, { showNotification })(Foo)

在本例中，调用了handleClick，但没有出现通知，但控制台中没有错误

贝娄是我对这个项目的依赖。

"dependencies": {
  "@material-ui/core": "1.5.1",
  "@material-ui/icons": "3.0.1",
  "apollo-boost": "^0.1.22",
  "apollo-link-schema": "^1.1.2",
  "graphql": "^14.0.2",
  "graphql-tag": "^2.10.0",
  "graphql-tag.macro": "^2.0.0",

  "graphql.macro": "^1.0.2",
  "material-ui": "^0.20.2",
  "ra-core": "^2.4.3",

  "react-scripts": "^2.1.1",
  "redux": "^4.0.1",
  "redux-thunk": "^2.3.0",
  "seamless-immutable": "^7.1.4"
}

如何在react admin应用程序中显示通知？我错过了什么？

动作分派器作为组件上的属性传入，因此名为mapDispatchToProps。因此，要调用动作分派程序，可以使用this.props.showNotification('Hello, World')
