I agree with John. For the most part, Flutter has been easier to maintain as time goes on when comparing to react native. And in the landscape, the people at Flutter appears to be very active with the framework, a lot of things cooking. Flutter web is very new, but it'll only get better, more stable.

For the most part, Dart/Flutter is a great choice for cross-platform application development. The platform is developed by Google, and will be around for a long time. Unless you need to do very low level stuff, like bluetooth tethering or 3D drawing, flutter should be able to handle anything you need it to.

We also had the same discussion, but ended with Flutter cause of it's great community support & great set of packages. Also achieving calling native feature is super smooth. And Flutter support Web as well while React Native don't. Learning curve is also a great point to choose flutter all doc's official videos are super rich to help you out.

We have experience with React Native, Flutter or Xamarin, the lion share of the native cross-platform tools used. They all allow you to create very good user experiences. You can check their reddit pages to see the beautiful designs people recreate. I highly recommend using cross platform tools vs native if your app has generic functionality that doesn't use advanced functionality of the app like VR/AR. So, for something like a dating app without those features, you would probably be better off with cross platform native instead of single platform native (swift/kotlin). If budget is low, a lot of companies have success just using Expo (a framework on top of React Native). It limits you further, but it's the easiest and most affordable to find developers with. Eventually you might decide to move away from it, but at that time ou ll have a lot more money and react native will be an easy tech to move towards.

As the previous commentor said, Next.js or React Native + Expo may be a better option. There's also the options of AssemblyScript + React/Next.js, or NativeScript and Ionic, both of which give you mature ecosystems of tools and close-to-native experiences. Flutter, you're likely to have the same experiences you had with Swift and Kotlin. Flutter requires higher separation of concerns between platforms, doesn't have nearly the third-party support of any of the other options, and is fairly large in binary size. Still, it's a growing system and in the future it may actually outcompete the other options when it has a large enough ecosystem.

Framework like Flutter or React Native can never replace native technologies, Both platform launches their features onto their official framework and Flutter or React Native adopt these new feature via their community support that so you might need to wait or you can write on your own. Also performance is a great factor if your are more focused on performance then it's always advised to go with native on. One of the emerging technology is Kotlin Multiplatform you can try this one if you are building app for both platform. KMM can help you to put all you business logic at single place and can construct UI on the native language.

If your team has a strong background in Python and you want to release some prototype soon, you could try Python and Kivy. Kivy is an open-source, cross-platform Python framework for rapid development of mobile GUIs. It supports both iOS and Android. I have passed a similar situation recently: to start a mobile app with no background in mobile development. Kivy saved me a lot of time. I could develop a prototype and release it faster than I thoght.

To be honest , You need to think these points :

If you already know how to build web apps, give Capacitor a try. You can think of it like "electron for mobile" in that you can build a web app but access native functionality. Pair it with Ionic if you want a UI kit that is optimized for mobile, or build your own UI from scratch.

Other tools have very slow performance. They are usually selected because someone on the team likes Angular, but your customers won't care what framework you're using. They'll just know the app is slow.

I think you should go with Flutter any day because there is a large variety of widgets inventory for it which can fasten up the development time to at least roll out a minimal viable product out there. Performance of Flutter Apps are also better than React Native apps. And as an added bonus, if in future you want to add a web interface for the same, you can do it using the existing codebase if written in Flutter (dart).

IMO if you need to build a simple and quick UI for your app, I'd suggest you go for either React Native or Android with Java or Better Yet, Kotlin (It won't take much time for you to get familiar with it if you know Java. See this https://play.kotlinlang.org/koans/overview). For Backend APIs you can use Python with something like Flask

If a web app would work, you can use your Python skills to build it quickly with Anvil. They handle hosting and deployment, with built-in database and user authentication. There's a drag-and-drop UI designer. But we're not talking a "no code" solution here. You write all the logic (both server- and client-side) in Python.

It depends. If you only need it to run on Android, you might be able to develop it faster in Android Studio (Java/Kotlin) with your experience with Java. Kotlin syntax is different than Java, but Android Studio has conversion from Java to Kotlin built-in.

I think in the long term Flutter would be your best bet, I work with both flutter and react native daily and I am constantly finding reasons why flutter is better then RN, some general things I've found with flutter are the following:

I have been exploring the Flutter lately it's good but if I am building something which is really huge then I will definitely use React Native for these reasons

Capacitor is a perfect tool for creating hybrid apps with any of the leading JS framework, so you don't have to worry about switching from JS to anything else. It also has a great ecosystem, as well as the native functions bridge plugins, most of them require zero-to-minimum effort to set them up. Unlike in React Native/Vue Native, you are not limited to specific components or logic, you are also free to choose any fitting UI kit, and the final product looks and behaves exactly the same regardless of the platform.

I would definitely go with Flutter. I have been writing native apps in iOS (Objective-C/Swift) and Android (Java/Kotlin) for over 6 years. For public-facing apps, we have generally written and maintained 3 code bases (iOS, Android, Web), so we have tried cross-platform solutions, including Ionic and React Native. React Native was definitely better than Ionic, but still lagged significantly behind native, in terms of performance. Flutter is a game-changer. I have been tasked with writing a public-facing app to help users identify fish species. It is backed with AWS Amplify (AppSync/GraphQL). I was able to write a platform-aware UI, with native-looking elements in less time than it would have taken me to write it natively for a single platform. It looks like with just a few UI and backend tweaks, we will also be able to deploy it for Web. I haven't run tests to confirm, but performance appears to be at least as good as native. Here are some additional benefits when using Flutter/Dart with VSCode:

I'll second the recommendation to check out Capacitor, optionally with Ionic. Capacitor provides a sort of "electron for mobile" that runs web apps on iOS, Android, Desktop, and as a PWA on the web, giving you access to the full native functionality on each platform through plugins or custom native code. Ionic then provides a native-quality UI layer and opinionated developer experience that ultimately uses Capacitor under the hood.

I don't know much about Xamarin but I know about PyQt and React Native.

It seems like your app is not really using any native functionality on the phone. I have experience with cross platform iOS & Android development. They are all really good tools! Xamarin (all the project on the website portfolio I attached) is awesome for accessing native functionality (NFC, Sensors, Bluetooth, etc), and I have built apps that have millions of downloads, some that hit Top 5 on Utilities, another that hit Top 50 in Finances. You just have to look at what your application intent is, it seems like it's just to read and post data. For that they are all pretty good, but you should also look into Ionic which may serve the same purpose

Choosing between ios/android and Flutter is not simple. Neither is a one-size-fit-all solution. It would be impossible to suggest one or the other without first analysing particular project’s requirements.

It's a bit late but I suggest staying on Flutter anyway. Though you might face troubles with APIs integration, overall development experience is better on Flutter, so you save some time & power on the project in general. Dunno if it's of any use to you, but as a prove I attach one of many Flutter vs RN comparison articles (you can find any other similar yourself on the web though), hope it helps you make a decision

can you discuss in more detail why cant you integrate that API?

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.

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!

Well, the first resource I would recommend you is my upcoming book by Packt Publishing, "Professional React Native", but it's due late January next year :) . Now jokes aside (the book's real by the way :) ), the easiest way to build a iOS/Android/Web app with React Native is to do: npm install -g expo-cli expo init some-project cd some-project expo eject

Vue Native is definitely production-ready in my experience. I've used both, have apps built with both in production right now, and both are fine technologies. As far as I can recall, there's nothing in RN that you can't do in VN. Given that, I would say go with "the devil you know".
