which is the best for mobile app development react.native or flutter ?
(cause I am react.js developer learning react.native was kinda fun)
and for real big projects using react.native & flutter better or useing java(android studio ) & swift(Xcode)?

[Lykkeskov]

I've created a few mobile and desktop apps with flutter, both using VS Code and Android Studio.
So far this has worked for what I needed it to, including stuff like connection to physical hardware over bluetooth and dynamic UI updates.
Granted these projects weren't very big and just for personal use, but the process wasn't too difficult and the outcome was also good.
I'm used to using PyCharm, so Android Studio was pretty easy to use, but VS Code also worked great, though I haven't tried Xcode.
Hope some of that helps.

If you're already familiar with React.js, React Native is a smooth transition — it reuses many patterns and feels familiar.

For large-scale apps, both React Native and Flutter can handle complex features, but native development (Java/Kotlin for Android, Swift for iOS) gives you more control and performance when needed.

Many teams mix both: use RN/Flutter for speed, and go native for critical parts.

React Native and Flutter both have their strengths for mobile app development. React Native is known for faster development times, especially for simpler apps, while Flutter excels in UI design and offers a single codebase for both iOS and Android. For large projects, using Java with Android Studio and Swift with Xcode is often recommended, as native development provides better performance and access to platform-specific features.
Choosing between React Native, Flutter, or native development with Java and Swift depends on the specific needs of your project, your team's expertise, and the desired user experience. For simpler applications or projects with tight deadlines, React Native or Flutter may be suitable. However, for larger, more complex applications requiring high performance and extensive platform integration, native development is often the better choice.

There’s no single “best” framework for every use case—it depends on your goals, team, and app requirements. But here are the most popular frameworks and what they’re best at:

✅ 1. Flutter
Best for: Cross-platform apps with a beautiful, custom UI

Why: Fast development with one codebase for Android/iOS/web/desktop, great performance (compiles to native), and strong community

Language: Dart

✅ 2. React Native
Best for: Teams familiar with JavaScript/React

Why: Reuses React knowledge, large ecosystem, decent performance

Language: JavaScript (or TypeScript)

✅ 3. Native Development (Swift/Kotlin)
Best for: Maximum performance, platform-specific features

Why: Direct access to device APIs, full native experience

Language: Swift (iOS), Kotlin (Android)

✅ 4. Xamarin (.NET MAUI)
Best for: .NET developers building for multiple platforms

Why: C# codebase, native performance, Microsoft support

Language: C#

React Native, you can write mobile apps for iOS and Andoid at the same time while keeping your code persistant, only small changes based on platform may be required on theming and on other little places but the main feature keeps the same

I recommend using React Native. It’s great for building apps that work on both Android and iOS with one codebase.

As someone who already knew a bit of React, it was super easy for me to get started. There are also a lot of helpful libraries you can use to add features to your app without too much extra work.

I recommend using FLutter, i use it myself and it is super useful

Hey! I’ve actually worked with React Native myself, and since you’re already into React.js, it’s a super smooth transition — honestly pretty fun, like you said. For big projects, React Native can totally scale if set up right, though sometimes native (Java/Swift) gives you more control and performance. Flutter’s great too, but if you're already comfy in the React world, I’d say stick with RN and go deeper. 🚀

[bekov28]

If I were you I would just stick with React Native, since you are already aware of JS and React.js and React Native is a more powerful cross-platform than you think. It's performance is near native-level unless you are aiming for high-performance apps, such as games or AR/VR. So it is better to go deeper with RN.

[AshirAzeem-Developer]

Honestly, if you already know React or JavaScript, React Native is the smarter pick — faster to learn, a huge community, and easier integration with native code.

Flutter is great too — polished UI, consistent across platforms — but it comes with Dart, which most devs don’t know, and the apps can be heavier.

So yeah, React Native is a better option overall, especially if you want quicker results and broad support.

I personally like flutter more. You can check out some of the projects i have built on my profile

I think Flutter is the best choice for mobile app development, especially for building high-performance, visually consistent applications across both Android and iOS. It offers excellent performance because it compiles to native code and uses its own rendering engine, which gives developers full control over every pixel on the screen. Flutter is also backed by Google and is designed for scalable, production-level apps, making it a strong option for large projects. While it requires learning Dart, the framework’s rich widget library and consistent behavior across platforms make development smooth and efficient. Compared to React Native, which is great if you already know React.js, Flutter tends to offer more reliable performance and cleaner UI results, particularly when advanced animations or custom designs are involved. However, if a project requires deep native features or platform-specific optimization, native development with Swift and Kotlin could still be the best route.

I would go with React Native for most use cases, it has a strong community, lots of libraries, and works well for both iOS and Android. If performance is a top priority, Flutter is also a solid choice since it compiles to native code and gives a smooth UI. It really depends on the project needs and the team’s experience.
