☀️ A Flutter package for some material design app intro screens with some cool animations.

IntroViews is inspired by Paper Onboarding and developed with love from scratch. I decided to rewrite almost all the features in order to make it available to the flutter developers and extensible as possible.

Getting Started

You should ensure that you add the intro_views_flutter as a dependency in your flutter project.

dependencies:
  intro_views_flutter: '^2.6.0'

You can also reference the git repository directly if you want:

dependencies:
  intro_views_flutter:
    git: git://github.com/aagarwal1012/IntroViews-Flutter

You should then run flutter packages get in your terminal so as to get the package.

Usage

• IntroViewsFlutter widget require a list of PageViewModel , and some other parameters. Refer the code below to create a PageViewModel page.

  Final page = new PageViewModel(
      pageColor: const Color(0xFF607D8B),
        iconImageAssetPath: 'assets/taxi-driver.png',
        iconColor: null,
        bubbleBackgroundColor: null,
        body: Text(
          'Easy  cab  booking  at  your  doorstep  with  cashless  payment  system',
        ),
        title: Text('Cabs'),
        mainImage: Image.asset(
          'assets/taxi.png',
          height: 285.0,
          width: 285.0,
          alignment: Alignment.center,
        ),
        textStyle: TextStyle(fontFamily: 'MyFont', color: Colors.white),
      );

• Now refer the code below to get the IntroViewsFlutter widget.

  final Widget introViews = new IntroViewsFlutter(
        [page],
        onTapDoneButton: (){
          //Void Callback
        },
        showSkipButton: true,
        pageButtonTextStyles: new TextStyle(
            color: Colors.white,
            fontSize: 18.0,
            fontFamily: "Regular",
          ),
      );

  For further usage refer the example available.

  For Landscape preview click the link.

  Note : If you added more than four pages in the list then there might be overlapping between page icons and skip button, so my suggestion is just make the showSkipButton: false.

This is the well documented package. I have documented each and every method that I have used, so have a good read to the code and suggest some changes and new feature to be added in the package. See Contributing.md. Feel free to open an issue.
