Flutter App Development – Everything You Need To Know
Do you want to develop mobile apps more quickly? And to reduce costs with cross-platform development? Of course, you are. That’s why in this article, we will give everything you need to know about Flutter App Development – from the app owners’ perspective.
Flutter is quickly becoming the go-to framework for cross-platform mobile app development. With a single codebase, developers can build beautiful, high-performance apps for iOS, Android, web, and even desktop. In this guide, we’ll walk you through everything you need to know about Flutter app development — including its key benefits, how it reduces costs, comparisons with React Native, and why it might be the perfect solution for your next project.
1. What is Flutter?
First, here is the basic (a.k.a essential) knowledge about Flutter app development.
Let’s put ourselves into the mind of a mobile app developer. You built a cool app, and everyone loves this. But there is just one problem: it’s only on iOS. So, every other day, you get the questions like “when is it coming to Android?”
It’s when you need cross-platform development like Flutter. With Flutter development, you can use the same code base to compile apps directly into machine code for Android, iOS, web, desktop, or anywhere that you might want to paint pixels on the screen.
2. Flutter app development: Advantages and Disadvantages
But which is like all programs, Flutter has both pros and cons. So that, in these paragraphs below, we will tell you what the advantages of Flutter are as well as some advice based on our experience.
2.1. Flutter Advantages
- Faster code writing: With Flutter’s hot reload, developers can check the effects immediately or without delay. In other words, your development team, together with QA engineers and designers, can cooperate more effectively, make quick changes, and see the outcome as well.
- Quicker time to market: As a business owner, you may think that one of Flutter’s biggest advantages is hiring one team for both iOS and Android platforms. However, another important benefit of Flutter is fast time-to-market.
- Less testing: Because you have the same application on both platforms, your quality assurance process will test less. Then it will be much faster.
- One single code base, for many platforms: Write once, deploy everywhere—mobile, web, and desktop. This greatly reduces maintenance and complexity.
- Native performance: The Flutter software uses an internal graphics engine known as Skia. This software allows for faster and well-optimized development than most other mobile app frameworks. A Flutter application will be ultimately indistinguishable from the native app.
- Beautiful UI: This year, Flutter partnered with Google Assistant and the Lenovo teams to host the most recent contest: Flutter Clock. We are always amazed by what developers around the world are building with Flutter. Let’s take a look at the following video:
- Perfect for MVPs: If you’re looking to test and assess your mobile app idea before moving forward with a full-blown software rollout, Flutter is the perfect option, especially if time is short.
- Low-cost app development:You only require one Flutter development team to develop and manage your apps for both Android and iOS versions. Hence, it significantly reduces expenses on human resources and shortens the time required to complete the development tasks.
2.2. Flutter disadvantages
- Small developer community: Flutter app development is making trend. However, it’s a relatively new tool that needs to do some catching up with more established frameworks. Therefore, the pool of developers fluent in Flutter will be moderately smaller than in the case of other tools and frameworks.
- Larger App Size: Flutter apps tend to be slightly larger in size, which might affect download rates in markets with limited data availability.
3. Why should you choose Flutter for cross-platform development?
While there are many cross-platform developments of apps, including Xamarin, developed by Microsoft, and React Native, developed by Facebook etc. Why should you choose Flutter for cross-platform app development?
- Fewer Development Effort – Cross-platform apps require less effort when comparing with native apps. Because developers can use a single code and reuse it on multiple platforms. Hence, the apps will be developed faster.
- Less Time In Testing – You don’t need to have separate quality analysts for each platform or multiple devices to check the app. Instead of two versions for Android and iOS, they have to test only one version of the app.
- Faster Development – What’s more? If you want to customize the app, it is easy for the developers to make the minor changes in a single code.
- Less Development Cost – As a result of all the above advantages, cross-platform app development reduces time to market. On the other hand, the cross-platform apps can run on both Android and iOS alike

4. How does Flutter reduce app development cost?
Let’s see what’s great about Flutter in this Developer Keynote (Google I/O 2021) below.
Flutter helps reduce app development costs mainly by using a single codebase for multiple platforms. Instead of building separate apps for iOS and Android, you only need one development team to handle both, cutting down on time, effort, and hiring costs.
Testing is also simpler. Since the app shares the same code, QA teams only need to test one version. This speeds up the quality assurance process and lowers the resources required.
Flutter’s hot reload feature boosts productivity by letting developers see changes instantly—no need to rebuild the app every time. It makes design tweaks, bug fixes, and team collaboration much faster.
Maintenance becomes easier, too. Updates or fixes only need to be done once, saving long-term costs and reducing the chance of platform-specific bugs.
A real-world example: ByteDance, the company behind TikTok, uses Flutter in over 70 apps. Their team reports that Flutter has helped them deliver new features 30% faster, making it a smart and scalable choice.
5. Flutter app examples
At Google I/O 2021, they also revealed that more than 200,000 apps are using Flutter in the Google Play Store, like WeChat, myBMW, and Grab. Not only that, within Google, more than 30 teams choose to build with Flutter for its productivity.
- Other popular names like BMW, SHEIN, DiDi, Grab, Alibaba, and Reflectly have Flutter-based apps.
- Innovative apps such as Kite (investment trading app) and Wombo (singing selfie app) are built using the Flutter framework.
- Toyota is bringing Flutter to its next-gen vehicle infotainment systems.
- Samsung is porting Flutter to Tizen (a Linux-based Operating System) with an open-source repository.
6. Flutter vs React Native: Which one is better?
Flutter is becoming the go-to choice for many companies when it comes to cross-platform development. One of its biggest advantages is its versatility—it allows developers to build not just mobile apps, but also web and desktop applications from a single codebase. This makes Flutter an excellent solution for projects with limited budgets and tight timelines.
Since its debut, Flutter has made a remarkable impact on the developer community and is showing strong potential to lead the cross-platform race. With the release of version 2.2, Flutter introduced a series of performance and stability improvements. Major tech players like Google, Microsoft, Samsung, and Adobe are also adopting Flutter, further solidifying its position in the market.
On the other hand, React Native remains a strong contender. Backed by Meta (Facebook), it continues to offer all the essential tools and components needed for robust cross-platform mobile development. Its mature ecosystem and large community make it a reliable choice for long-term projects.
In the end, the choice between Flutter and React Native often comes down to your specific project requirements, team expertise, and long-term vision.
Quick Comparison:
| Feature | Flutter | React Native |
|---|---|---|
| Owner | Meta (Facebook) | |
| Programming Language | Dart | JavaScript (and TypeScript) |
| Performance | Near-native, thanks to compiled code (Skia) | Good, but relies on bridge for native modules |
| UI Components | Rich set of built-in widgets for iOS & Android | Uses native components via JavaScript bridge |
| Development Experience | Excellent tooling with Flutter DevTools | Mature, with strong support in VS Code & others |
| Community & Ecosystem | Growing fast, still younger | Larger, more mature community |
| Platform Support | Mobile, Web, Desktop (Windows, macOS, Linux) | Mobile (iOS, Android), some Web/Desktop via 3rd-party |
| Learning Curve | Slightly steeper (Dart is less common) | Easier (JavaScript is widely known) |
| Corporate Support | Backed by Google + used by Microsoft, Adobe… | Backed by Meta + large open-source contributors |
Conclusion
Flutter has emerged as one of the most promising trends in mobile app development, especially since 2021. With strong backing from Google and rapid improvements in each version, it’s positioned as a top contender to lead the cross-platform space shortly.
