警告:componentWillReceiveProps 已被重命名，不建议使用

Question

我使用createBottomTabNavigator.

在我的课堂上

const Tab = createBottomTabNavigator({
MainScreen: { screen: MainScreen },
SecondScreen: { screen: SecondScreen }
});
const Container = createAppContainer(Tab);
export default class App extends React.Component {
state = {
isReady: false
};
componentDidMount = () => {
this._load();
};
render() {
const { isReady } = this.state;
if (!isReady) {
return <AppLoading />;
}
return <Container />;
}
_load = async () => {
try {
this.setState({ isReady: true });
} catch (error) {}
};
}

这是我的包.json

"dependencies": {
"expo": "~36.0.0",
"react": "^16.12.0",
"react-dom": "~16.9.0",
"react-native-gesture-handler": "^1.5.2",
"react-native-web": "~0.11.7",
"react-navigation": "3.0.8"
}

这是我的错误

Warning: componentWillReceiveProps has been renamed, and is not recommended for use. 
* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps.
* Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE_ name will work. To rename all deprecated lifecycles to their new names, you can run `npx react-codemod rename-unsafe-lifecycles` in your project source folder.
Please update the following components: SafeView

我做了npx react-codemod rename-unsafe-lifecycles但没有用。

即使在使用最新的 React 版本react-navigation3.x 后，它也会继续发生，因为react-navigation取决于"@react-navigation/native": "^3.6.2"，它使用"react-native-safe-area-view":"0.11"，而SafeAreaView使用已弃用的方法。

4.0.x 版本的 @react-navigation/native 使用 0.14，已更新

因此，升级您的反应导航。希望对您有所帮助。随意怀疑
