It has been evident that the demand for mobile apps has exponentially grown, with around 3.5 billion smartphone users in 2020 and predicted to have reached 3.8 billion users in 2021. The reason behind this is the developers’ rising interest in creating applications with a highly responsive and engaging user interface.

In 2015, Google announced a substantial change in its search engine algorithm and a new regulation requiring websites to be mobile responsive first. From there, designers have realized the value of building responsive architecture in both desktop and non-desktop applications. Still, they also like creating responsive UI in-app to improve user experience.

In practice, however, designers face a complex problem in creating responsive UIs in applications.

Whether it’s customizing modifications in the app, auto-rotating content to fit the screen, or making it suitable with both tiny and large screens, the app development companies can get you covered. Your app must be responsive to layout changes at all costs.

What is Flutter?

Flutter is Google’s mobile app SDK. It includes a framework, widgets, and tools to simplify developers creating and launching visually appealing, quick mobile apps for Android and iOS. Flutter makes developing cross-platform mobile apps painless and straightforward. You don’t need to create separate iOS and Android apps. All you need is a single codebase.

Some more features of Flutter

• Flutter is free and open-source software.
• Flutter is built on Dart, a quick, object-oriented programming language that is simple to learn in and of itself.
• Provides its widgets, which are rendered using a high-performance rendering engine. They’re quick, attractive, and adaptable.
• Flutter apps look and feel excellent, thanks to the rich widgets.
• You can create your unique app design, and you can also use readily available UI elements that meet the platform’s requirements.
• Flutter’s architecture is based on today’s top-rated reactive programming.
• It’s quickly catching up to React Native, as well as native app development.

Flutter marks Google’s remarkable accomplishment in two key areas. These two key areas are building a platform-agnostic framework for Android and iOS native apps. These work great in production and creating a genuinely platform-agnostic framework for Android and iOS native apps. A web app development company can help you build a flutter app that you need.

Why is Flutter gaining so much popularity?

1. A cross-platform framework enables developers to create apps for both iOS and Android using the same code.
2. Flutter is an open-source framework. This means that it’s free to use and comes with a wealth of documentation and community assistance to help even beginners get started.
3. Because it is built on Google’s in-house language, Dart, this framework is straightforward to learn and use.
4. Despite its youth, Flutter has attracted the attention of major corporations such as Google, Alibaba, eBay, Emaar, and others.
5. The hot reload functionality makes launching or upgrading a Flutter-based app a breeze.
6. Developers may change the code in real-time on emulators, simulators, and hardware without restarting the app. This makes app development companies love Flutter.
7. It’s one of the main reasons Flutter is the first option of developers when it comes to creating UIs, fixing problems, and adding new features.

Hopefully, you’ve realized why Flutter has become so popular for app development. When creating a responsive layout in an app, Android and iOS take different ways to handle forms for different screen sizes.

But why do you need responsive mobile app design?

Responsive design refers to using a single code set that adapts to variations in device layout. The UI of the responsive app adjusts to the device’s screen size and shape. An app with a responsive UI can run on various devices, including smartwatches, phones, tablets, and laptops, without building numerous interfaces.

When the user resizes the window on their laptop or changes the orientation of their phone or tablet, the same software will alter the page size to fit the screen. This shows us why responsiveness is an essential factor for designing mobile apps.

Why should you use Flutter in your Mobile Apps?

You may feel that Flutter’s great, but why should I use it to design my mobile apps, or why ​​ do app development companies prefer Flutter? Or how do I integrate Flutter with my mobile apps? You may feel like a beginner, clueless and thinking about starting, but trust the process; Flutter will help you grow your app development.

The following are the important benefits from the standpoint of an app owner: Flutter enables your team to create a beautiful app UI with seamless animations while also speeding up the mobile app development process and lowering app development costs.

We are simply now talking about the pros of Flutter. These are explained well in detail, which will essentially convince you why you should start designing your mobile apps using Flutter. They are listed here.

Faster code writing

Flutter allows a web app development company to create more dynamic and faster mobile apps. We can change the code and immediately see them in the app! This is called a “hot reload,” which takes only a few milliseconds. It also allows teams to experiment more, add features, and correct errors quickly. These are a few features of Flutter that every top Flutter app development team adores.

When we wish to change or experiment with an app’s look and examine the impacts on the spot, hot reload also incredibly convenient in developer-designer collaboration. In other words, with Flutter, your designer or tester may collaborate on the UI with a developer, making adjustments – such as “Put it 2 pixels right” or “Speed up the animation” – and seeing them immediately.

However, in the case of native app development, the project must be recreated, which takes substantially longer. You must wait for every change – sometimes for several minutes.

One code for two platforms

E-commerce web development services developers design a single codebase for your two apps covering both Android and iOS platforms. Because it has its widgets and designs, Flutter isn’t reliant on the forum.
It would be like you’ve got the identical app on two different platforms. What’s essential is that you can differentiate your apps if you want to.

Less testing

It’s easier to test if you have the same software on two platforms. The Quality Assurance process might be made more efficient. Because there is only one codebase, the developers only have to write automated tests once.

Moving ahead, because there is just one app to check, Quality Assurance specialists have less work to complete. Naturally, if your apps differ in some way, they must be evaluated on both platforms.

Faster Apps

Flutter apps run smoothly and quickly, without stuttering or cutting out when scrolling. There are many Flutter technical app articles available online if you want to know why and how it works from a technical standpoint. Also, look at the Flutter documentation regarding app performance recommended practices.

Designs that your users will love

Flutter is made to make it simple to develop your widgets or tweak the ones that already exist. On Flutter’s official website, you can browse through a catalog of Flutter’s widgets. Flutter can view thousands of authentic and beautiful yet unique app designs here.

You can also use these widgets and templates for your app. Flutter allows you to do so. It also provides you with basic templates and structures to design your app from scratch.

The same app is compatible with older devices as well.

Even on older Android and iOS platforms, your new app will look the same. Supporting outdated devices does not incur any further expenditures. Flutter requires Android 4.2 or later and iOS 8 or later.

Perfect for MVP!

Do you require an MVP (Minimum Viable Product) to demonstrate to your investors your app? Flutter is ideal, especially if you’re short on time.

Is Flutter appropriate for all types of mobile apps?

There are a few situations when it’s worth considering whether Flutter will be a good fit:

Instant Apps & Progressive Web Apps

They must be compact, and Flutter apps, even when optimized, are more significant than native apps. Depending on whether it’s a release or development build, the overhead ranges from a few to 20 MB. It’s worth noting that Google only allows apps to be 10MB in size.

Apps that use Bluetooth to communicate with any hardware
If you wish to utilize Flutter to create an app with these characteristics, you can:

Develop these features individually for iOS and Android, then use platform channels to integrate them into the main Flutter app. In this scenario, it’s difficult to say whether it will save you more time than developing two 100 percent native apps.
Using an existing Bluetooth plugin for Flutter, such as FlutterBlue, simultaneously develops these capabilities for both platforms.

As mentioned earlier, Flutter is still in its youth, so some people might think that it isn’t good enough. Agreed, Flutter has gained so much popularity but it still isn’t rich enough. Rich when it comes to widgets, packages, libraries, etc.

But day by day, Flutter is being upgraded. With new features and updates continuously being added on, Flutter is developing into every mobile app developer’s first choice.

There are almost 200 open issues and 36 awaiting Pull Requests on the FlutterBlue repository on Github (as of 06-12-2019). These figures indicate that many people are working to develop the Flutter software.

In the case of fast-evolving technology like Flutter, frequent plugin updates are critical — and it has recently been upgraded.
