Flutter Loader Widget:

A Flutter loader widget is basically a circular object which spins over the screen and tells that something is actually getting loaded and it spins till the code is executed. Nowadays, loaders play a important role in all applications, be it a mobile application or a web application. In this fast growing environment, the data should load in a fraction of eye blink, as users will not wait too long to see the application running. Meanwhile when the data takes a few seconds to load, then comes the actually role of the loader wherein it keeps spinning on the empty screen which tells the user that something is actually running on the back-end and will soon appear on the screen. Thus it makes the user feel that the data is being loaded rather than looking at the empty screen until the data loads.

So, are you ready to use the loader which plays an important role in any applications and that makes it a user friendly one. Here i am going to use an open-source UI Library known as GetWidget to build this widget. Here is a short introduction about GetWidget Loader widget and why i am using this.

First, Let go with Getting started, It will guide you how to start building a beautiful flutter application UI with GetWidget UI library. Now, we have to install the GetWidget package from pub.dev, To import the package in your Flutter project follow the below guide.

Install Package from pub.dev :

https://pub.dev/packages/getwidget - Check the detaila about GetWidget Package.
