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.
GetWidget Loader is a simple yet very useful component used widely in any applications. It spins in a circular manner in the centre of the screen and indicates that something is getting loader and appears soon on the screen within a fraction of seconds. In day-to-day lives people are so used to mobile applications and are on the edge to see the data or the objects on their screen when-ever they open any apps.In this case the loader helps and spins over the screen which indicates the data is being loaded.
GetWidget loader is not only a circular loader, its more than a basic and a circular loader.It is widely divided into basic, ios, circular, square,loaders. So, let's get into one by one and make use of them efficiently.
Basic loader is a simple and a android type of loader which can be used in any applications and gives a simple and elegant look to the applications.
Ios loader is used in any kind of applications, be it a android or a ios apps.
Circular loader is a circle type of loader and is different from basic loader. A circular loader is a full rounded type of loader and can be customized with any colors of choice.
Square Loader, as the name itself defines, it is a loader of square type and can be customized with any colors.
Custom loader is such a loader in which the user can use any kind of icons, images, text as the loader and show them spinning on the screen until the data loads.
How to Start:
Now, here is the guide about how we should you can start developing Flutter Toast Widget with the help of GetWidget UI Library.
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.
Import full package:
Note: dependencies: getwidget: ^1.0.11
Keep playing with the pre-built UI components.
Example of a simple Basic Loader which acts as a android loader:
import 'package:getwidget/getwidget.dart'; GFLoader(),
Example of Ios Loader:
import 'package:getwidget/getwidget.dart'; GFLoader( type:GFLoaderType.ios ),
Example of Circular Loader:
import 'package:getwidget/getwidget.dart'; GFLoader( type:GFLoaderType.circle ),
Example of Square Loader:
import 'package:getwidget/getwidget.dart'; GFLoader( type:GFLoaderType.square ),
Example of Custom Loader:
import 'package:getwidget/getwidget.dart'; GFLoader( type: GFLoaderType.custom, child: Image(image: AssetImage(your gif here...), ),
Example of Custom Loader with icons:
import 'package:getwidget/getwidget.dart'; GFLoader( type: GFLoaderType.custom, loaderIconOne : Icon(Icons.insert_emoticon), loaderIconTwo : Icon(Icons.insert_emoticon), loaderIconThree : Icon(Icons.insert_emoticon), ),
Example of Custom Loader with Text:
import 'package:getwidget/getwidget.dart'; GFLoader( type: GFLoaderType.custom, loaderIconOne : Text('Please'), loaderIconTwo : Text('Wait'), loaderIconThree : Text('a moment'), ),
Now, let's see the types of loaders altogether in the following example:
