How to Make a Flutter App [Beginners]

Introduction:

There was a time when businesses relied upon traditional avenues such as brick and mortar spaces, telephone, and formal letters for sales and service goals. Not anymore! Today, the same business entities exploit desktops and laptops for the said tasks.

In fact, even these platforms are shrinking as people around the world have switched to smartphones to buy products/services, and that too with just a few taps. How? Of course through dedicated mobile applications.

Mobile App:

No wonder the manufacturing, trading, and services industries are migrating to this intuitive way of attracting customers, and at the same time engaging and addressing their issues quickly. While the number of mobile app users in developing nations is growing in double digits every year, the developed countries have already reached several milestones in terms of usage. So, what makes these apps so popular? There are several reasons, and some of the compelling ones are mentioned below.

– Mobile Apps are intuitive.

– Light-weight and therefore do not hog memory.

– Apps are easy to operate.

– responsive in terms of display and accomplishing day-to-day tasks.

In short, they have become an integral part of human lives. Whether you want to book tickets, order food from a restaurant, purchase goods or watch movies online, the buzzword is Mobile App.

Some of the business areas where these applications play a crucial role –

Healthcare

Companies can quickly update, send important messages and reminders to their customers through these applets. It is not only cost-effective but an amazing way to address customer issues in real-time.

After Sales Service

Now, this is one area where businesses can really make a big impact. By responding to service requests quickly, manufacturing and trading companies can build a large base of happy customers. This, in turn, would provide a span and spike for future growth.

Standalone Application

Standalone mobile applications such as inbound and outbound CRM’s can help businesses connect with customers in a seamless manner, address bottlenecks, liaise with sales folks, and schedule meetings to pursue daily goals. Moreover, app data can then be exploited in an intelligent manner to chalk out future plans.

It is because of these reasons that the mobile app market is growing at a scorching pace, as more and more businesses realize the benefits of providing one for their customers. Furthermore, apps assure enormous growth and provide that humane touch and a link between the company and the customers/vendors. That it simplifies business process cycles in yet another feather in its cap.

Interestingly, Flutter Software from Flutter Development Company makes the app building process less tedious. Mentioned below is a beginner example of how to build a “Hello World” application in Flutter?

Simply install the Flutter application after downloading from the developer website and then run the following command. Incidentally, there is no need for any supplementary compilers or programs.

So, why do we need to initiate this step? The answer is to know if all the components and dependencies have been registered properly. Mentioned below is a typical output after running the above command. What you need to remember is that not all the components are required, especially the editor which you can choose as per your taste.

Once the desired environment is created choose a location for building your first application and then execute the following –

The above command/instruction/code will create the following directories and files

Congratulations! The raw shell for the application has been created which due to its simplicity utilizes just a single file – main.dart. The next step is to delete the content of this file and replace it with the following code.

So, what does the above code mean? The first line in the code requests material.dart, a repertoire of various components/widgets existing within the application IDE also called the library. These are buttons, forms, layouts, animation, etc. The next line of code “runApp” builds a local widget within the root widget.

As mentioned above Flutter app development is all about widgets ( built-in and customized ).

The next two lines specify the state of the widget ( Stateless or Active state ) which is typically achieved via the createState() method. This app fits into the former category and therefore requires a “build” command. A stateless app such as those with just text or images is easy to build and execute. The final step is to run this code.

Thankfully, Flutter does the same from the same window and does not require a different compiler/execution platform. Depending on your preferred method and connected device choose any one of the following options.

You can also use built-in simulators in case no devices are connected.

Interestingly, Flutter is based on an object-oriented programming framework boasting intriguing concepts in the form of native components that allow programmers to create intuitive and highly complex applications that are flexible, secure and future-ready, and demand ridiculously low development period.

Tagged as one of the most popular frameworks, Flutter offers amazing application components such as animations, digital motion work, and a plethora of native features. Moreover, these apps are responsive and therefore device-independent.

Here are some of the silent features which are sure to make any new app programmer smile.

Cross-Platform Code

Write a single piece of code for iOS and Android platforms. Yes, Flutter uses single source code to build cross-platform applications. This not only saves development costs but also reduces development time drastically.

Built-in Widgets

Built-in widgets and customization allow programmers to create apps rapidly. Materials or widgets form the very essence of Flutter which is easy to deploy and edit.

Quick Deployment

Experimentation with various widgets, code, and components is super simple. This, in turn, reduces testing time, and therefore deployment too is also quick.

Hot Reload

This is one feature that makes Flutter stand out in a crowd of other IDE’s and development platforms. Hot reload your application after every bug fix or design modification to see the changes. There is no need for an external compiler or decoding platform.

Hassle-free Maintenance

When it comes to application maintenance Flutter is second to none. Because of its ready-made widgets, the code is minimized which in turn reduces redundancy.

If you are a beginner mobile app programmer or planning to work for a Softwar e Development Company you should try Flutter. It is a feature-rich and future-ready IDE that boasts cross-platform compatibility and easy integration of third-party components.
