问题 My Idea: I want to use the Firebase Auth Plugin in Flutter to register the users. But before they can access the App, they have to verify their Email address. Therefor I push the Firebase users after registration to a verification screen. This is just a loading screen wich tells the user that he has to verify his email. But now: How can I continuously listen, if the users email is verified or not and send him (when true) to the Homescreen? I'm new to Flutter and I don't know if I have to use

问题 I am building a map related component where the properties like center zoom features will be pushed to the component by props . When the map component are mounted, I will set the map view and add some features according to the props . And when the state changed I am not sure if updating the map view by componentWillReceiveProps is the right way. Also, when user intereact with the map, the map view will change which means the internal state of the map compontent have changed, is it necessary

问题 I am recently learning Angular 6 with @ngrx/store while one of the tutorial is to use @ngrx/store for state management, however I don't understand the benefit of using @ngrx/store behind the scene. For example, for a simple login and signup action, previously by using the service(Let's call it AuthService) we might use it to call the backend api, store "userInfo" or "token" in the AuthService, redirect user to "HOME" page and we can inject AuthService in any component where we need to get the

问题 I am researching into what is the best way to store the UI state, Should I use something like Redux-UI (https://github.com/tonyhb/redux-ui) to store/manage the UI state? or should I create my own actions/reducers for the UI? Also... when I have stored the UI state, how do I make sure if the browser is refreshed, I still have exactly the same state of the page? Just as a normal web page would including Data taken from the server. I have Redux with thunk middle wear implemented and a store. I

问题 As suggested here in the Mobx documentation I have created multiple stores in the following manner: class bankAccountStore { constructor(rootStore){ this.rootStore = rootStore; } ... class authStore { constructor(rootStore){ this.rootStore = rootStore; } ... And finally creating a root store in the following manner. Also I prefer to construct children stores within master's store constructor. Moreover, I found that sometimes my child store has to observe some data from parent store, so I pass

问题 What are the do's and don'ts about Cache VS Session VS Cookies? For example: I'm using Session variables a lot and sometimes have problems in a booking-application when users start to order products and then go to lunch and come back some hours later and continue the booking. I store the booking in the session until the user confirms or aborts the booking so I don't need to talk to the database and handle halfway bookings in the database when users just click the X in the browser and never

问题 I am learning ngxs but I can't understand when should I use patchState and setState ? What's the difference? const state = ctx.getState(); let data = this.service.list(); ctx.setState({ ...state, feedAnimals: data }); vs. let data = this.service.list(); ctx.patchState({ feedAnimals: data }); 回答1: Those two pieces of code are equivalent. patchState is just a short hand version of the setState({...state, ... } code. In future patchState will most likely be evolving to a more useful immutability

问题 We are using Asp.net Session in our application for state management. By default, In-proc mode is being used. But now, we have to look for an alternative as we have been asked to remove Session from our application by our client due to performance issue. One of the way is to keep everything at Client side say in hidden field on Postback. It's not a good approach for sure. Is there any other way of doing it? Im sure there would be an alternative. PS: Please don't suggest Querystring. Thanks,

问题 I'm trying to understand the accepted answer for Persisting DataSource in GridView after PostBack as I have a similar problem. Quote: I steer clear of putting stuff into the VeiwState or session unnecessarily, so I think the best way to persist this data is to Cache it. When I look at the MS suggestions for state management: ASP.NET State Management Overview caching is no where to be seen. There is a comment (search for Jim_Huff), asking about this, but it isn't answered. Question : What's
