HashCode | Its purpose is to encode your desired hash text | Hashing library

I have a spring boot application with spring web & spring data cassandra as dependencies. And I have a main method in a class annotated with @SpringBootApplication.

I have the following entities:

Hi Everyone, I am new to dart, I tried to implement memoization but it is not working, please tell me how to implement memoization. Thanks in advance.

Hash Functions are incredibly useful and versatile. In general, they are used to map a space to one much smaller space. Of course that means that two objects may hash to the same value (collision), but this is because you are reducing the space (pigeonhole principle). The efficiency of the function largely depends on the size of the hash space.

It comes as a surprise then that a lot of Java hashCode functions are using multiplication to produce the hash code of a new object as e.g. follows (creating-a-hashcode-method-java)

I have been working on a flutter app and recently installed three firebase related pacakges firebase_core,cloud_firestore and firebase_storage. But after installation when I try to import them in a .dart file I am facing 'The system cannot find the path specified

import 'package:quiver/core.dart';' error. So what should I do ,here is my pubspec.yaml file . I even tried adding quiver to the pubspec.yaml if that could fix the erro but it didn't.

I know this question was asked multiple times but I'm loosing my mind, I'm trying to create a Many-To-Many relationship and I'm getting the following exception:

I am using .Net Core 3.1 with React, Typescript and webpack for an SPA. I have multiple modules in react which I load on different page/view of Asp.Net core application.

I am facing issue with auto refresh or hot reload. When I change a parameter which I am passing from module to a component hot reload works as expected BUT if I do any change in component then those are not getting reflected in browser.

If I browse https://localhost:5010/webpack-dev-server I can see home.bundle.js there. Also if change value of "msg" param/prop of HomeComponent in HomeModule.tsx, I can see new bundle generated for home.bundle.js with fresh hashcode and change also reflects to browser on https://localhost:5010/home/ BUT If I do change to HomeComponent.tsx ex: if I change "Home component" to "Home component 123" this change not getting reflected neither on https://localhost:5010/home nor the new bundle NOT generating on https://localhost:5010/webpack-dev-server.

Here is my project structure and files including configuration files. Any help will be highly appreciated.

Update: I added HotModuleReplacementPlugin to webpack.dev.config.js and now when I modify something in component HomeComponent.tsx I see a new entry in https://localhost:5010/webpack-dev-server something like "5f80de77a97d48407bd9.hot-update.json". If I open this file it's content is like {"h":"0dce1f9e44bff4d47fb4","c":{}}

Apart from this another issue is when I run application with F5 from Visual Studio it takes couple of seconds to load website until than browser shows "This site can't be reached"

Project stucture

Sorry for my english I'm French.

I develop in Flutter (dart) and I experience a strange behavior in my code using Cubit (Bloc) when I want to redirect to a page after a form submission (with "Reactive forms" package, but also with classic form) and the step of the Cubit loaded state: I see 2 calls to the page (2 builds) which gives a sort of "flapping" effect which means that the final user sees the interface charging twice.

It's my first application in Flutter.

I created an application containing a login form: when the form is submitted I print another form.

At the beginning of my application I was using "auto_route" package and I obtained a refresh of the page each time I clicked inside the text field after the login process. So I was not able to write anything inside the text field.

I was thinking that the problem came from the "Reactive forms" package so I opened an issue to the github repository of this package: issue opened

But as I didn't see where was the problem I came back to a much more basic development for my application and also a more basic method for managing the pages routing in order to explain my problem to the maintainer of the "Reactive forms" package, a really nice guy which really tried to help me.

But even the maintainer does not understand why I have this problem.

Now I reduced my more simple code in one page.

For the moment I don't have the problem when I clicked inside the text field but I see that interface is built twice and the Cubit loaded state which maybe explains why I had the initial problem.

So now I try to understand why the interface is built twice before debugging my original code.

I think my main problem is that the Cubit loaded state is waiting a synchronous widget return but when I try to redirect to a another page it needs an asynchronous action (with "auto_route" package or more simply using "Navigator.push()" action).

But I don't know how to call a Future inside a Cubit loaded state which wait a classic Widget.

I tried this:
