Hello coders.

I am Kumar Lakshmanan from codingfrontend.

Last 3 months I learn Google flutter framework to create Android apps. Yeah this is my second project in flutter. This is a simple project to change your wallpaper dynamically from internet. 
I hope you like this Android app and also this app is user friendly.

I use API integration to fetch photos from website. I will spend 20 days to create this app and thousand lines of code in dart programming language. Finally, yes I will make it.

What is flutter ?

Flutter is Google's portable UI toolkit for crafting beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.

What is Dart ?

Dart is a client-optimized programming language for apps on multiple platforms. It is developed by Google and is used to build mobile, desktop, server, and web applications. Dart is an object-oriented, class-based, garbage-collected language with C-style syntax.

Flutter and Dart .

Dart is the programming language used to code Flutter apps. Dart is another product by Google and released version 2.1, before Flutter, in November. As it is starting out, the Flutter community is not as extensive as ReactNative, Ionic, or Xamarin. ... Dart looks a bit like C and is an object-oriented programming language.
