• This PR is for issue 🥃Splash Screen App #4 i.e. Splash Screen App

Proposed Changes

• Made splash screen for the application using the dark theme.
• I removed an unused dependency in the pubspec.yaml file i.e. assets/icons/ otherwise it was showing an error in the console.

Additional Info

• The UI code for the splash screen can be found in lib/src/screens/welcome/welcome.dart and I also made separate widgets for the page, so it is easier to read. The widget related code can be found in lib/components/welcome_splash.dart and I had to create a model for each splash page that can be found in lib/model/welcome_model.dart.
• Added a new route i.e. to splash screen in lib/routes/navigation_route.dart.

I made splash screen for your application. All the code can be found in welcome.dart. I divided my code into separate files so that it is easier for reading purpose. I have followed all proper naming conventions. The separate widgets that I made for the application can be found in welcome_splash.dart. Since all the screens had same theme, a photo, a heading, a caption, and an index. So I created a separate model class for it welcome_model.dart. I created a new controller WelcomeController for the navigating between the pages and to store the content of the page and also for the pagination below the images. The skip button on the splash screen will navigate you to Home screen. There was also an unused dependency lying in pubspec.yaml file, I removed it as well.

I have made the splash screens for your application. For splash screens to work I added new files such as a new model and a new controller to handle the navigating and the content of the splash screen.

It solves issue #4
