Fin*_*ish 3 javascript reactjs flowtype react-native react-navigation
我正在开发一个简单的React Native App,并决定使用用户react-navigation。我还决定使用Flow进行静态类型检查。我不知道的是如何使用Flow定义与导航相关的道具。
例如,我将App.js定义为使用StackNavigator,如下所示:
import StackNavigator from 'react-navigation';
import Main from './app/containers/Main';
const App = StackNavigator({
Main: { screen: Main },
});
export default App;

然后我定义了Main类,但是我不知道如何在我的道具中引用react-navigation:
// @flow
import React, { Component } from 'react';
import { View, Text } from 'react-native';
type Props = {
navigate: ????
};
type State = {};
class Main extends Component<Props, State> {
...
}

根据https://github.com/react-navigation/react-navigation/issues/3643
import { NavigationState, NavigationScreenProp } from 'react-navigation';
type Props = {
navigation: NavigationScreenProp<NavigationState>
};

react-navigation有一个流文件。也许您可以从那里导入或只是复制粘贴
