In today’s competitive app market, businesses are developing hybrid applications to create versatile applications that work seamlessly across multiple platforms. Flutter has emerged as the leading choice for developers and companies alike. But why is Flutter considered the best platform for hybrid app development? This article explores the advantages of Flutter and why many companies are opting for it to build cross-platform applications.

What is Flutter?

Flutter is an open-source UI software development kit (SDK) created by Google. It allows developers to create natively compiled applications for mobile, web, and desktop from a single codebase. With a growing developer community and continuous updates, Flutter has gained massive popularity for its ability to deliver visually appealing and highly functional hybrid apps.

Advantages of Flutter in Hybrid App Development

1. Single Codebase for Multiple Platforms

One of Flutter’s biggest strengths is its ability to develop apps for both iOS and Android using a single codebase. This eliminates the need for separate development teams for each platform, saving time and resources. By leveraging Flutter’s “write once, run anywhere” approach, developers can ensure consistent performance and appearance across platforms, leading to faster development cycles.

2. Fast Development with Hot Reload

Flutter’s hot reload feature allows developers to instantly see changes made to the code without losing the app's current state. This significantly speeds up the development process by enabling real-time iteration and testing. With quicker debugging and faster adjustments, Flutter helps developers deliver high-quality apps more efficiently.

3. Customizable Widgets for Flexible UI

Flutter offers a rich library of pre-designed and customizable widgets that make UI development both flexible and intuitive. Whether you need a native look or a customized design, Flutter provides the tools to create a smooth user experience. The ease of designing attractive interfaces without compromising functionality gives it a huge edge in hybrid app development.

4. Excellent Performance

Flutter doesn’t rely on WebView components or JavaScript bridges, unlike other hybrid frameworks. Instead, it uses Dart, a modern programming language that compiles native machine code. This ensures Flutter apps perform nearly as well as native apps, offering smooth animations and fast response times that are critical for a good user experience.

5. Vibrant Community and Ecosystem

Another significant benefit of Flutter is its growing community and support ecosystem. The platform is backed by Google, which means continuous improvements, reliable updates, and a plethora of libraries and plugins to extend its functionality. Whether you're a Flutter app development company or a solo developer, the availability of community support can help you overcome challenges during the app creation process.

Why Choose Flutter for Your Next Hybrid App?

Choosing Flutter can provide businesses with cost-effective and future-proof solutions. With access to top-notch tools, reusable code, and superior performance, Flutter app development services offer a reliable path for hybrid apps that don’t compromise on quality. As more industries lean toward hybrid development, Flutter’s versatility makes it the go-to choice.

Conclusion

Flutter offers great performance and is lightweight, which led it to gain fame among app and game developers. Read more to discover why the flutter app and game development have become popular. If you are planning to Best Game app development for users and Gamers read this blog I highly recommended it.

Even though Flutter delivers high-performance apps by default, there are some common pitfalls potentially slowing down the functionality. Experts suggest practices that can help you overcome these errors and ensure optimized app performance.

There are plenty of Flutter performance tuning methods to follow, which results in developing the best and optimized app. We are going to discuss some of the best Flutter performance tuning practices.

The flutter framework does an amazing job just by being super faster that too by default. However, that doesn’t mean you’ll overlook its performance completely. Every new technology or trend has its own pros and cons, and so is the case with Flutter app performance, it is extremely slow comparatively. Besides this, you can utilize this framework to make your apps not only fast but efficient and less CPU time and battery consuming.

Flutter framework was introduced by Google a few years back, so for performance optimization, you need to keep some guideline in mind, which are as follows:

Update state only when you must

Don’t target many widgets when updating the state

Don’t involve computationally intensive task outside your build methods.

So the hard truth about flutter performance optimization is “everything depends” on your app. You can only test to get the right solution to each problem while performance optimization.We would like to share some basic advice being flutter developers, what we’ve experienced so far:

Basic advice

Never commit the mistake of testing the flutter app when it’s in debug mode, perform the test when it’s in profile mode.

Always make sure that you run your flutter app on real advice rather than iOS stimulator or Android emulator. No doubt, these software emulators are great for testing but they have a certain characteristic, which is not the right fit for flutter apps.

If possible keep one real device aside for testing flutter apps and don’t use it for any other purpose.

CPU/GPU governors

Modern operating systems often vary the frequency of each CPU and GPU at their dumping as per the load and some other heuristics. However, while running a flutter app test on Android device you can turn off these governors that process is recognized as “scale locking”. Follow the below steps:

Create a script that scale-locks your performance-test device

If you want something generic and lightweight, then look at the following example that shows you the excerpt sets of CPU to the user governor.

Keep in mind, that your aim here is not to fuel real-world performance, but to have comparable metrics between the runs.

Then you need to experiment and tailor the shell script to the device you’ll be using.

Flutter Driver

Flutter driver allows you to implement your app automatically. Here’s how:

Don’t implement your app manually when testing the performance of your app, use Flutter drivers to ensure that you’re comparing every aspect of the flutter app.

Make sure you write an effective flutter driver code so that it implements and provide you with what you really want to measure. If you’re developing a general app try to walk through every aspect of your flutter app being a user.

In case, if your app has an element of chance mock those out.

If you want to add custom timeline events you can do so by using Timeline’s startSync () and finishSync () methods.

It is crucial to saving both the summary and imperatively the raw timeline while running your flutter app test.

For every version of your test, implement it many times

Timeline

Timeline is the raw output of your profile runs that flutter dumps in JSON file and you can load it into chrome://tracing.

You need to learn how you can open a full timeline in Chrome’s tracing line timeline. All you need to do is just add chrome://tracing in a browser in Google Chrome and click on “Load” and select the JSON file.

Make use of WSAD keys to walk around the timeline in chrome://tracing and 1234 change modes of operation.

If you’re setting your performance testing for the first time, then consider running Flutter driver with full Android systrace. This will give you a detailed insight into what’s actually happening in the device, including CPU scaling information.

Now how you can run test on full Android systrace? First, begin Android systrace with: /path/to/your/android/sdk/platform-tools/systrace/systrace.py–atrace-categories=gfx,input,view,webview,wm,am,sm,audio,video,camera,hal,app,res,dalvik,rs,bionic,power,pm,ss,database,network,adb,pdx,sched,irq,freq,idle,disk,load,workq,memreclaim,regulators,binder_driver,binder_lock. Then start the app with: flutter run test_driver/perf.dart –profile –trace-systrace. In the end, start the Flutter Driver with: flutter drive –driver=test_driver/perf_test.dart –use-existing-app=http://127.0.0.1:NNNNN/.

Metrics

We recommend you to look at as many metrics as possible, yet we’ve outlined some useful ones being experienced flutter’s i/O app developers:

Build times and rasterization times are only implementable for rigid performance tests that don’t comprise much besides building UI.

We suggest you to not to view timeline frame as a way to compute frame per second (FPS) because flutter profiling tools doesn’t equip you with real frame rate information.

You retrieve maximum data by measuring the total CPU time spent running Dart code. This count codes execute themselves every time, be it in your build methods or outside them.

One of the best and easiest way to understand the total CPU time spent running Dart code is to measure the extent of MessageLoop: FlushTasks events in the timeline.

Results

Once you’re done with setting up your flutter app performance, you’ll be able to compare experiments and commits with confidence. Here’s an answer to your common dilemma “Is this optimization worth the maintenance overhead?”

It seems that in this specific scenario the answer is “Yes”. With only a few more lines of codes, each automated walkthrough of your apps takes 12% on an average less time of CPU.In a nutshell, we would say that you should embrace this sentence “it depends” forever when running performance optimization for your flutter apps because in another scenario it might show you up some different results.
