Wallpaper App made with Flutter with Dynamic Theming.

Wallpaper App made with Flutter

This is a wallpaper app made with flutter.

This is just a UI demo. If you want to learn how to apply an image as wallpaper, check out reWalls

Concepts used:

• State Management using Provider
• Dynamic Theming
• Navigation Using PageViews and BottomNavigationBar

EXCEPTION CAUGHT BY RENDERING LIBRARY

Got this Error when changing theme:

Can you change wallpaper on IOS using this app?

I'm just curious if IOS allows you to change the wallpaper using fluter apps.

New logo/icon proposal

Good day sir. I am a graphic designer and i am interested in designing a logo for your good project. I will be doing it as a gift for free. I just need your permission first before I begin my design. Hoping for your positive feedback. Thanks

the method dispatch is not defined for class ChangeThemeBloc

I would like to contribute in your project

Hey, I am Siyona. I would like to contribute in this app can you please assign me task.
This is for my open source contribution class
