Well, first of all, if you don’t know what Flutter is, it’s an app SDK (Software Development Kit) by Google to help you develop the modern native apps UI with latest resource enablement and technical superiority. This is done with the help of the supporting latest tools and documents it comes with, to help you with the advanced app UI development needs you have. 

How Flutter helps – in a real-world scenario

Here, let’s take a case of a gaming app like virtual Ludo. Now, this app requires more than one member to play at a time and that’s all in a real-time sync. A programmer developing such an app with a host of Graphic UI elements, functional logic building, and user-interactive features requires about a 50 day of time to code and build a Ludo app, including the time to learn Flutter. And all this doesn’t require any sort of proficiency or expertise with the mobile app development languages or any supported training related to building an app. 

However, that comes even better when you have worked with the technologies like Android/Java and iOS/Swift for building apps in past. 

So, if you compare it with the time of putting up with the earlier technologies, it appears to be just about one-third of that. Your grasping speed and approach towards understanding and applying concepts of course gets you going pretty faster than that. With that you can say that Flutter helps you build fast and most importantly with great level of execution.

Going with the Reactive style

Let’s first find out how do you begin with architecting an app for native platforms like iOS and Android using Flutter.

Firstly, you must be prepared to work on a reactive framework. If you haven’t yet, it should be a learning curve for you. When you are well inducted with Flutter’s approach and reactive paradigm, you are all prepared to build an app on the framework. 

To give you a taste of it, so let’s say you have to work on a Hello <name> app. It would reflect the name entered by the user. Also, let a user to choose the color of the text as per his wish. In a reactive style of coding there is a listener to track changes in the TextField and the Dropdown values. We can enter/change these values in the ‘global state’ and ask Flutter to re-paint. It will accordingly make entry/changes on the Text label. This allows the listeners to stay the same while the new widget repaints itself as per that state. 

As the apps and their requirements get more complex and lengthy, it becomes furthermore helpful going with the reactive references as you get to do updates and changes on a large number of such fields allowing you to scale benefits. Also, with this public API, it was highly simplified. Take a look into how the code looks like for the Text Widget in Flutter. 

class Text extends StatelessWidget {

const Text (this.data, {
    Key key,
    this.style,
    this.textAlign,
    this.textDirection,
    this.softWrap,
    this.overflow,
    this.textScaleFactor,
    this.maxLines,
  }) : assert(data != null),
       super(key: key);

/// The text to display.
  final String data;

  final TextStyle style;
  final TextAlign textAlign;
  final TextDirection textDirection;
  final bool softWrap;
  final TextOverflow overflow;
  final double textScaleFactor;
  final int maxLines;

@override
  Widget build(BuildContext context) {…}

@override
  void debugFillProperties(DiagnosticPropertiesBuilder description {…}
}

This is the brevity and neatness it puts up with to offer you a great interaction value and easy reference through the code.

Everything Widget 

Now, there is something that makes it to deliver a high level of ease and fluidity to the process of development by interacting with well-laid widget-wide library. The new widget architecture favors to derive composition out of the widget elements over limiting them to mere structural elements. So, you get to work with a more powerful, compliant and composable set of Widgets – for just everything you do to build an app with Flutter. 

A Widget can be anything from a structural element (like a menu or button), a stylistic element (like a font or color scheme) or even a facet of layout (like padding). Now, when you get widgets for everything you get to develop your app quite easily and interactively, while being able to reach your app interface in style and with great control over object rendering, composition, collaboration and execution.

No more activity lifecycle management 

Rarely you would find a developer who likes to manage activity lifecycle. Mostly, because it is more like a peripheral activity and does not directly aid to production. But, going with Flutter you do not have to manage it as it is not required as all the activities are streamed through a connected patch where they get traced and loaded in a synchronous manner. So, whether it is about an Activity, Fragment or ViewController, you just don’t need to put up with those sluggish and lengthy ways of managing activity lifecycle. Brilliant. Isn’t it?

Consistent 60 FPS (Frames per second) 

This one is big reason why Flutter makes it to the finest of performance in building a gaming or graphic-rich app. Because of its reactive nature and Dart (compiled programming language replacing JavaScript bridge) support, UI development and rendering become highly compact and swift, allowing it to deliver highly steady visual results with a consistency rate of 60 frames per second. This makes it a highly good contender for native app development for advanced interfacing and visual engagement requirements.

The community support

As Flutter allows you to access a large collaborative community of expert developers and support resources, it becomes really easy to learn, refer, confirm and go about app development effectively. The community forum called ‘Flutter gitter channel’ brings together a large number of seasoned and aspiring developers who greatly contribute to the platform with their expansive curiosity, knowledge, learning and insights to achieve best of value and output working with the platform. Which sums up to no stuck-ups, doubts, misfortunes and best of community support for anything and everything around Flutter.

End Notes

All that put together justify and elucidate the fact that Flutter is one of the most progressive and reliable UI framework SDKs to go with for a native app development. It simply proves that you can reveal great possibilities and prominence out of your app development idea, going with something like Flutter that embraces the best of reactive approach coupled with high-quality and consistency, well backed by a great community support. And the best part is it continues to grow at a fast rate to offer you the most of native UI development possibilities needed by you with time.
