我想整合mobx https://mobx.js.org/ and mobx-坚持 https://github.com/pinqy520/mobx-persist with 反应导航 https://reactnavigation.org/.
我读过这些文章:

[4] MobX + React Native:注入存储的方式 https://stackoverflow.com/questions/45670065/mobx-react-native-way-to-inject-stores
[5] MobX - 当我可以在将数据注入 React 组件时使用“inject”时,为什么我应该使用“observer” https://stackoverflow.com/questions/48437102/mobx-why-should-i-use-observer-when-i-could-use-inject-when-injecting-data
[6] 在 React 组件中注入 Store 会导致错误 https://stackoverflow.com/questions/46139278/injecting-store-in-react-component-results-in-error
但我仍然遇到这个错误:
undefined is not a function (evaluating 'decorator(target, property, desc)')
这是我的 App.js 渲染:
render() {
const hydrate = create({
storage: AsyncStorage
});
hydrate('playerStore', stores.PlayerStore);
hydrate('settingStore', stores.SettingStore);
// .then(
// // () => console.warn('some hydrated')
// );
return <Provider {...stores} >
<AppWithNavigationState />
</Provider>;
}
这是我的routeStore.js:
import {observable} from "mobx";
import {action} from "mobx-react/native";
import AppDrawer from "../appDrawer";
import {autobind} from 'core-decorators';
export default class RouteStore {
@observable.ref navigationState = {
index: 0,
routes: [
{ key: "R1", routeName: "ContentStack" },
],
};
@action
dispatchNavigation(action, stackState = true) {
const previousNavState = stackState ? this.navigationState : null;
return this.navigationState = AppDrawer.router.getStateForAction(action, previousNavState);
}
}
这是我的 appWithNavigationState.js:
import React from 'react';
import {observer, inject} from "mobx-react/native";
import {addNavigationHelpers} from "react-navigation";
import AppDrawer from "../appDrawer";
@inject(stores => ({ routeStore: stores.RouteStore }))
@observer
export default class AppWithNavigationState extends React.Component {
render() {
return (
<AppDrawer navigation={addNavigationHelpers({
dispatch: this.props.routeStore.dispatchNavigation,
state: this.props.routeStore.navigationState,
})} />
);
}
}
我还使用装饰器包,如下所示:
npm install babel-plugin-transform-decorators-legacy --save-dev
并且这个设置在babelrc
file:
{
"presets": ["react-native"],
"plugins": ["transform-decorators-legacy"]
}
你能帮我解决这个问题吗?
