What Is Flutter App Framework?

In short, Flutter app development platform is a hybrid mobile development platform with UI tool kits which have a native feel to them even though they are hybrid made. Flutter app development platform comes with pre-coded UI elements such as menu bars, buttons and more. These pre-coded elements are made with google material design for android devices and Cupertino for iOS, in fact, flutter app development platform uses Dart which is an object-oriented programming language. Dart shares a huge amount of its coding practises with Kotlin and Swift, which is the foundation for Android and iOS respectively So when compared with other development platforms such as Xamarin, Ionic and Cordova, Flutter app development is much more close to the native platform when compared any other Hybrid mobile development platform.

What Does Flutter App Do?

Flutter app development platform outclasses its competition by having precoded UI elements and widgets which cuts down time on developing time and coding errors. Flutter app development platform is a mixture of native codes of Android and iOS which is buoyed by DART foundation. Flutter app development platform makes it easier for developers to put in time coding functionality of the application instead of wasting time on coding for the front end part of the application.

How To Program In Flutter App Framework?

To start programming in Flutter app development platform, one only needs to know the basic concepts of programming such as loops, conditions, variables and syntaxes. The programmers do not need experience in coding with Kotlin or Swift or in Dart for that matter. Developers need to go to Google’s codelab to start coding, the developers will code the core of the program in OOPS format and execute it When completed the codelab will show the program in Swift and Kotlin program. Developers will need to choose between the Android Studio or iOS simulator as the primary platform. Codelabs will choose Android Studio as default but developers will have the choice to choose otherwise. Once this is complete developers can choose between pre coded UI elements or can create a new one. Flutter app development platform also comes with pre-coded widgets native to both iOS and Android respectively.

How To Run Flutter App In Android?

To run a flutter app in android, first, the application needs a launcher icon which can be uniquely created or a one can be chosen from the flutter_launcher_icons package. Incase of a unique icon, developers need to follow guidelines prescribed in Material Design. After the icon is finalized, the application needs to be digitally signed. Next, the entire codes of the application are shrinked with R8, this enabled by default by Google Play store.

The Flutter application needs a manifest, this manifest contains the app name, label and tag lines. The manifest, more importantly, contains all the permissions needed from the user to execute the application on their device. In the next step, build configuration is done, here developers need to input application id (applicationId) which has to be a unique and final id given to the application.  Next developers need to input the internal version name and number of the application (versionCode & versionName). Next, the minimum and existing API levels need to be specified, (minSdkVersion & targetSdkVersion).

Next step is to make the Flutter app into an apk for uploading to the google play store. Before uploading developers need to go through a checklist which deals with language localizations, distribution to other Google platforms such as google home, google wear, smart TVs and more. Application listing tweaks for the end-user for better visibility of the application. Once this is done, update your application with a new version and your application is ready for deployment.

Can Flutter App Be Used For iOS?

Yes, Flutter app uses the Dart programming language which is a mix of Swift and Kotlin, Swift is the base programming language for iOS devices. Flutter app development platform comes with pre-coded settings for Xcode, this makes the development for the front end a breeze when compared with other hybrid mobile development platforms.

Our Mobile application development process

Learn how we approach your mobile development application requirement, it’s not just coding that goes into the process, we have digital artists, marketers, quality analysts and business analysts who contribute their individual competencies

Concepts and research

First, we answer some questions which an end-user could ask before him/herself before installing and your application

Why choose your application?

How much better is your mobile application than your competitor’s mobile application?

How much easier is it to use this application than the other application?

Will this application be stable all the time?

Will this application do what the other application with lesser clicks?

The answers to these questions give us what the end goal of your application should be, it may be the core functionality or it could be user experience and most of the time it is both. We identify the target demographics of your application, the competitors of your application, research what they got right, what they got wrong and where we can be better than them and fill the demand gaps in the market. We come up with concepts which will give your application the edge in the marketplace while being better than your current competition.

Realistic Goals and Timeframe for Flutter App Development

The next step is to decide between what is feasible and realistic within a given time frame. Here clients and developers come to a consensus on what the end goal should be given. Functionality and features are decided on, this will make sure that end product and clients demands and expectations are the same. This is an initial and critical stage of the Flutter mobile app development cycle, which drives the rest of the process with a clear and precise end goal.

Flutter Prototyping & Wireframes

Here the Flutter app is given a wireframe, this will finalize the placements of buttons, sliders, images and more. When creating a complex mobile application, wireframing helps developers and digital artists to have a vision of what the final application will look like. Wireframe also gives the initial mould to clients about their Flutter app’s look and feel.  A wireframe can serve as a checklist for APIs, servers, data diagrams, data integrations, push notifications and other technical aspects. Wireframing also provides a canvas to digital artists to unleash their creativity and give the Flutter app a better user experience.

Development Of The Flutter Application

Once the wireframing is done and everybody is on the page of the team, the flutter app development starts, coding is done in Dart programming language, the codes are executed on both Android studio and Xcode to make sure that the application has similar performance and feel in both the individual platforms. While the Flutter app is hybrid in nature, developers need to tweak the hybrid Flutter app to be as native as possible. Strict standards are maintained as the application needs to be stable, look and feel native and outperform the competition. Even though Flutter comes with plenty of pre-coded UI elements and widgets, all elements of the application is custom made and designed to give the end-user a one of a kind experience

Flutter App Debugging & Testing

Here things are more complicated than usual since our Flutter app, complicated in the sense that codes here are debugged individually. This answer questions such as how to debug flutter app on android or how to debug the flutter app on iOS, the answer is they are not debugged as flutter app, instead they are individually debugged in Android Studio for the android side of the application and in Xcode for the iOS side of the application. This is done so that the Flutter app meets the individual guidelines set by the individual platforms. By individual standards, iOS has much stricter guidelines and takes a longer time for approval when compared with the Android Play Store. The end-user also prefers a bug free application for obvious reasons.

Launching the Flutter application

Deployment of the flutter app happens on individually, these native platforms have separate checklists for approving the application for their individual apps store. For Apple’s app store it takes around 2 to 7 days for approval and the Android Play Store takes around 2 to 4 hour for approval.  Parallelly our marketing team optimizes your application’s metrics attracting the target demographics and to increase the marketing team launches marketing campaigns, creates marketing collaterals and landing pages to maximize your brand and application to a wider audience.
