How to Develop Flutter App for Beginners and Benefits

There was a time when companies relied on traditional avenues like physical spaces, the phone, and formal letters for sales and service goals. Not anymore! Today, the same commercial entities exploit desktop and laptop computers for such tasks. In fact, even these platforms are shrinking as people around the world have switched to smartphones to purchase products/services and that too with just a few taps. How? Of course through dedicated mobile applications.

It’s no wonder that manufacturing, retail, and service industries are migrating to this intuitive way of engaging customers while quickly interacting with and addressing their issues. While the number of mobile app users in developing countries is growing by double digits each year, 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 applications are intuitive.

– Mobile applications are lightweight and therefore do not hog memory.

– Mobile applications are easy to operate.

– Mobile applications are responsive in terms of viewing and performing daily tasks.

In short, they have become an integral part of human life. Whether you want to book tickets, order food at a restaurant, buy products or watch movies online, the buzzword is mobile app.

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

Healthcare: Businesses can quickly update, send important messages and reminders to their customers through these applets. Not only is it cost-effective, but it’s also an amazing way to address customer issues in real time.

After Sales Service – This is an area where companies can really make a big impact. By responding quickly to service requests, manufacturing and marketing companies can build a large base of satisfied customers. This, in turn, would provide a lag and peak for future growth.

Standalone App – Standalone mobile apps such as inbound and outbound crms can help businesses seamlessly connect with customers, address bottlenecks, communicate with sales staff, and schedule meetings to meet daily goals. Furthermore, the data from the app can be intelligently exploited to map out future plans.

It is for these reasons that the mobile app market is growing at a dizzying pace, as more and more companies realize the benefits of providing one for their customers. In addition, the applications ensure enormous growth and provide that human touch and link between the company and customers/suppliers. That streamlines business process cycles is yet another feather in your cap.

Interestingly, Flutter Software from the Flutter Development Company makes the app building process less tedious. Here is an example for beginners on how to create a “Hello World” app in Flutter.

Just install the Flutter app after downloading it from the developer’s website and then run the following command. By the way, there is no need for additional compilers or programs.

Check the code here.

So why do we need to start this step? The answer is to know if all the components and dependencies have been registered correctly. Here is a typical output after executing the above command. What you need to remember is that not all components are required, especially the editor, which you can choose according to your taste.

Once the desired environment is created, choose a location to build your first app, then run 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, uses a single file: main.dart. The next step is to remove the contents of this file and replace it with the following code.

So what does the above code mean? The first line of code requests material.dart, a repertoire of various components/widgets existing within the application’s IDE, also called a library. These are buttons, forms, layouts, animations, etc. The following line of code “run application” build a local widget inside the root widget.

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

The next two lines specify the state of the widget (stateless or active state) which is typically achieved via createState() method. This application fits into the above category and therefore requires the “compile” command. A stateless application, such as ones with only text or images, is easy to create and run. The final step is to run this code. Fortunately, Flutter does the same thing from the same window and doesn’t require a different compiler/execution platform. Depending on your preferred method and connected device, choose any of the following options.

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

Interestingly, Flutter is based on an object-oriented programming framework that features intriguing concepts in the form of native components that allow programmers to build highly complex, intuitive applications that are flexible, secure, and future-proof, and require a period of time. Ridiculously low development. Tagged as one of the most popular frameworks, Flutter offers amazing application components such as animations, digital motion work, and a host of native features. Also, these apps are responsive and therefore device independent.

Here are some of the quiet features that are sure to make any new application programmer smile.

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

built-in widgets – Built-in widgets and customization allow developers to build apps quickly. Materials or widgets form the very essence of Flutter, which is easy to implement and edit.

Quick implementation – Experimentation with various widgets, code and components is super simple. This, in turn, reduces the testing time and therefore the implementation is also fast.

hot refill – This is a feature that makes Flutter stand out from a crowd of other IDEs and development platforms. Reload your app after each bug fix or layout change to see the changes. There is no need for an external compiler or decoding platform.

Hassle-free maintenance – When it comes to app maintenance, Flutter is second to none. Due to its out-of-the-box widgets, code is minimized, which in turn reduces redundancy.

If you are a beginner mobile app programmer or planning to work for a software development company, you should give Flutter a try. It is a future-proof, feature-rich IDE with cross-platform compatibility and easy integration of third-party components.
