App Development in Flutter for Beginners

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

No wonder then 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.
  • Mobile apps are light-weight and therefore do not hog memory.
  • Mobile apps are easy to operate.
  • Mobile apps are responsive in terms of display and accomplishing day-to-day tasks.

In short, now they have become the need of human lives. Whether you want to book tickets, order food from 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 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 app building process less tedious. Mentioned below is a beginner example on how to build a “Hello World” application in Flutter?

Simply install 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. import ‘package:flutter/material.dart’; void main() => runApp(new HelloWorldApp()); class HelloWorldApp extends StatelessWidget { @override Widget build(BuildContext context) { return new MaterialApp( home: new Material( child: new Center( child: new Text(“Hello world!”), ), ), ); } }

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 createState() method. This app fits into the former category and therefore requires “build” command. A stateless app such as those with just text or image is easy to build and execute.

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