Question

我刚开始在反应原生项目中使用flow。对于大多数反应原生api来说，看起来已经有很多很好的流式输入。但是如何让我的流式类型检查器在我的项目中使用它们呢？

这是一个不起作用的例子：

// @flow
import { StatusBar } from 'react-native';

const fn = () => {
  StatusBar.setBarStyle('this-is-not-in-enum');
};

对StatusBar.setBarStyle的调用应该根据react-native源代码中的流类型生成流错误。您可以在https://github.com/facebook/react-native/blob/0.42-stable/Libraries/Components/StatusBar/StatusBar.js#L201

中看到该代码

我的.flowconfig：

[ignore]
; We fork some components by platform
.*/*[.]android.js

; Ignore templates for 'react-native init'
.*/local-cli/templates/.*

; Ignore the website subdir
<PROJECT_ROOT>/website/.*

; Ignore "BUCK" generated dirs
<PROJECT_ROOT>/\.buckd/

; Ignore unexpected extra "@providesModule"
.*/node_modules/.*/node_modules/fbjs/.*

; Ignore duplicate module providers
; For RN Apps installed via npm, "Libraries" folder is inside
; "node_modules/react-native" but in the source repo it is in the root
.*/Libraries/react-native/React.js
.*/Libraries/react-native/ReactNative.js
