Hey, If you are using Unity you are going to have to do the end to end development on Unity, you can directly build for android and iOS on Unity. I dont see how Flutter or React Native fit into this equation. Unity is a standalone engine. As for Social Chats, you could use Firebase or your own API and integrate that in Unity in C#

I agree with Sahil. If Unity is a requirement, best way is to use just that to create your app.

If you really want, it should be possible to use Flutter and Unity together. Using Flutter Unity Widget. Although I wouldn't recommend it just yet. It's too early days.

If you do end up using it, I would be very interested in reading about your experiences.

You can start by small steps with Flutter and after Unity. Flutter = best choice to build a small cross-platform mobile app. With or no flutter, use directly Unity. Y'll have complete control but it's harder for new mobile developers. Keep in mind, the requirement is Unity!

Given your experience in electron I think the shortest hop is going to be React Native. Especially since half of the requirements are server-side. Google is doing a pretty great job bringing up Flutter and the tooling is pretty great. For me however, dart seemed like quicksand and not everything is in its final home. React Native is mature, and considering my cursory analysis of your experience and the low complexity of this project, you've got quite a lot of room to grow into Javascript Land. Ultimately, my recommendation is always "play with both, see what you like, and get to know the documentation and the community." Keep your head on a swivel and set aside time to peek greener pastures, but spend most of your time delving deeply into what you're already doing.

But yeah, go with React Native first, get bored of it, learn what the shortcomings are through experience and then see if something else is really more attractive or just a new shiny.

Well, I will personally recommend to go for React Native as I have worked in both of them. React native has big community and it is easy to opt as compared to Flutter. There no doubt about the fact that Flutter is a great framework for developing both Android/IOS apps. However, you should have some experience to go for the same. Both will require prior knowledge as for React Native you have to go through Javascript first with which you are already familiar and for Flutter you need to go through Dart. So being familiar with Javascript you should go for React Native. You can go expo which has lot of inbuilt functionalities for the React Native developers.

I would never recommend you to go with Ionic, Because of the User experience it provides is subpar. Flutter is most promising, Can be easily used to develop great user experience in no time. React native is also good, but it's phasing out in my opinion, while Ionic has already phased out. Flutter also provides great developer experience, resulting in fast and productive developers. I would have to press hard to think of a CON about flutter when recommending it for your needs.

Maturity, Community, Facility, Libs React Native is the principal platform of mobile cross-platform development today, Flutter is it's a promise.

Even if React Native is older (I didn't say mature) you should go for Flutter, It's works really well and the developer experience is great (auto-completion, plugin etc). I spent years with React Native and now I am using Flutter and I don't regret It. Even if you have to learn a new language, It's pretty simple even more If you know some OOP, Java and Javascript ES6 syntax in some case. One other advantage is the facility to design app in Flutter, you have widgets for everything and you can adapt any design made by your designer. For example you can't make a simple custom box shadow with React-Native ...

Flutter is built on DART which is written in GO. GO compiles to binary. Hence is faster than any java based framework. It provides superior performance and has a simplified UI process for designing apps.

I don‘t have practical experience with flutter but between ionic and react native I‘d say both a perfectly viable options and we have used both for a number of production apps. We normally go with ionic on capacitor because we build a lot of pwa/web apps so we can use the same code for all. We don‘t use much of ionic elements, we do most styles on our own.

The comments that the user experience is bad I cannot agree with. A well designed and developed ionic apo can hardly be distinguished from a native app. But obviously that depends also on the usecase and type of app.

I hope this helps

It depends also on your team skills. Flutter is fast to learn, fast to develop with and the performance is much better in comparison to React. If your team is already highly skilled in React Native it could be the better option - if not Flutter is my 100% recommendation. We rapidly prototype and deliver MVPs with Flutter since two years.

It's probably not relevant anymore, but I think Ionic with Angular as the frontend is the right choice. For IDE I would choose Visual Studio Code. You can just create a basic web application with responsive design, which is already included if you are going to use Ionic components with Material Design to create your app. You don't need to know Swift, you don't even have to create mobile apps, just create a responsive (Ionic already is) web app, or PWA. Upon browsing your website from a mobile device for example using google chrome, you will be prompted to create a shortcut of the website in your mobile phone. After you do this, there will be an icon in your phone that looks like an icon to launch an app, it will launch your website in full screen mode - for the user's perspective it will look like he is using a native app. Access https://ionicframework.com/docs/angular/pwa from your android chrome browser, go to tab options (3 vertical dots), click on Add to Home screen. When you launch the website from the shortcut, you'll see that it behaves and looks like a native app.

I think you should chose between Flutter and Ionic. With those two options, the main question is about graphs and performance. Are they really important for your application? If the answer is yes, your tool is Flutter but, if the answer is that you need an easy tool to create an app with some basic components I would choose Ionic. You have a library with lots of components that you can use and they have native UI by default (for Android and iOS).

You will find more support if you use Ionic with Angular as frontend framework (you have the option to use Vue or React but this is a new feature for Ionic and I think there are more difficult to learn than Angular).

You can develop and debug the majority of features on PC (I don't know if that is possible with Flutter). And when you will finish the app, create iOS and Android versions is simple.

Flutter is easy to use and easy to understand. Once you have completed the android platform, you can easily build it to ios, Web or desktop on a single code base.

1. Electron is for desktop apps, so not useful for you.
2. Flutter has better performance, but Ionic is decent as well, I would use Ionic unless you're making a game or graphic-intensive app.
3. Ionic is more flexible since you have the whole NPM ecosystem available, while flutter is more recent, thus libraries for it are less in quantity and battle-tested than the ones in NPM.
4. Ionic 4 introduced CSS variables, which improved immensely the theming process for the app, which was the hardest issue Ionic development had.
5. Ionic has extended to many frameworks so it's compatible with Angular and React frameworks, meaning more flexibility, personally I would recommend Ionic with Angular over React since it's more suited to enterprise-level apps.

Hi there. So Electron embeds everything in a webview, which means that what you would have to develop would be a Node project most probably. Ionic does the same (kindof but won't bore you with specifics) but it does it much more efficiently. Usually you do Ionic apps with JS frameworks like Angular or React (this one recently added). Flutter on the other hand does native apps, it does it really good but it's support for Web is in beta and it's relatively simple to setup if you already know the SDK and the environment.

My recommendation would be that you do your app using Angular/Ionic if you reaaally need the multi-platform environment and there's different reasons in this case:

• Since it's a graduation project you need it to be as simple as it can be and adding a new technology adds to the learning curve.
• Flutter is great if you have different complex UI or if you have specific performance needs that require native support and in your case it does not seem like you need that.
• Flutter is also an incredibly powerful tool but it's learning curve might be tricky if you have not developed native apps before so I wouldn't recommend you start off like this if you have time sensitive projects like a graduation project. It does have great docs and an awesome community but I'd suggest you stick as close to what you know as you can.
• Ionic/Angular uses Typescript (a type javascript wrapper) and Angular (JS framework) so you will have to learn a little bit but if you already know HTML, CSS and Javascript you won't have that much of a hard time. Also there's quite a lot in terms of documentation and tooling already tested around this combination.
• Ionic/Angular has a really good CLI that helps you stick to the architecture they recommend so you wouldn't have to worry about it that much.
• Ionic/Angular helps you test either locally in the web browser as well as your devices which is in the end what you want if you are looking for a multi-platform system. Flutter also does this but is not quite in a stable state (yet!).

Anyway, in the end, if you go for the multi-platform suggestion I think, because of time you would be better off with Ionic. If you decide that you don't need that as of right now (which is fine as well) you can start with just the Android app and plan on the different things you might eventually need like a website or other different stuff. Cheers!
