The package will allow you to simulate the Netflix app menu behavior.

The class i created is just a simple imitation, so there can be stack memory problems or graphical performance issues on older devices.

HOW TO USE IT

You need page_transition (at least version 1.0.0) and after_layout (at least version 1.0.5) in order to use this package.

After you have imported it, you should create your personalized Stateful or Stateless Widget classes. After you did this, on your main default function you have to create a list of objects and to return the NetflixAppBar instance.

• LIST OF OBJECTS

  Let's create a simple list of objects

  //we initialize the list
  List<DrTextTransitionTitleObject> titles = new List();
  
  //we add a new Widget class, one of them you created
  titles.add(new DrTextTransitionTitleObject("title", "slug", your_class_name()));

• NetflixAppBar ARGUMENTS

   NetflixAppBar(List<DrTextTransitionTitleObject> titles, int duration,
        {Widget header,
        double headerHeight = 0,
        Color background = Colors.transparent,
        Color appBarColor,
        int dumping = 100,
        double titlePaddingLeft = 16,
        double titlePaddingRight = 15,
        double titleActiveFontSize = 20,
        double maxOpacity = 0.6,
        double initialOpacity = 0,
        bool pinned = false,
        TextStyle titleStyles = const TextStyle(
          color: Colors.white, fontSize: 16, fontWeight: FontWeight.bold),
        Widget leading,
      Function(ScrollController, String, NetflixAppBar) onScreenChange})

Example:

    List<DrTextTransitionTitleObject> titles = new List();

    titles.add(new DrTextTransitionTitleObject("Movies", "movies", Movies()));
    titles.add(new DrTextTransitionTitleObject("Tv Series", "tv", Tv()));
    titles.add(new DrTextTransitionTitleObject("About Me", "about", AboutUs()));

    int milliseconds = 700;

    TextStyle titleStyles = const TextStyle(
        fontFamily: "Dr1",
        color: Colors.white,
        fontSize: 18,
        fontWeight: FontWeight.bold);

    instance = NetflixAppBar(
      titles,
      milliseconds,
      initialOpacity: 0.3,
      maxOpacity: 1,
      dumping: 100,
      titleStyles: titleStyles,
      titleActiveFontSize: 21,
      appBarColor: Colors.black,
      background: Colors.black,
      onScreenChange:
          (ScrollController controller, String slug, NetflixAppBar instance) {
        print("Controller received correctly \n We are on $slug screen");
        this.currentSlug = slug;
        this.instance = NetflixAppBar.getInstance();
        var newTitles = this.instance.titles;

        //....

      },
    );
    return instance;

IMPORTANT

after the first screen transition the class that wraps NetflixAppBar instance will be disposed, so be careful.

STATIC FUNCTIONS

• getInstance()

  NetflixAppBar.getInstance() will return the current NetflixAppBar instance. So you can get info about current titles, attributes, and so on

• notify()

  NetflixAppBar.notify() will allow you to update graphical elements on the current displayed screen

• goBack()

  NetflixAppBar.goBack() will allow you to return to the previous screen

• DrTextTransitionTitleObject ARGUMENTS

  DrTextTransitionTitleObject(String name, String heroTag, Widget function,
        {List<DrTextTransitionTitleObject> newTitles,
        bool personalized = false,
        Widget overrideWidget,
        Function overrideAction,
        TextStyle primaryStyle,
        Widget header,
        double headerHeight,
        double paddingLeft = 0})
  

Example:

    List<DrTextTransitionTitleObject> titles = new List();
    List<DrTextTransitionTitleObject> tvTitles = new List();

    var movies = new Movies();
    var tv = new Tv();

    titles.add(new DrTextTransitionTitleObject("Movies", "movies", movies,
        header: switchHeader("movies")));
    titles.add(new DrTextTransitionTitleObject("Tv Series", "tv", tv,
        newTitles: tvTitles, header: switchHeader("movies")));
    titles.add(new DrTextTransitionTitleObject("About Me", "about", AboutUs()));

    tvTitles.add(new DrTextTransitionTitleObject("Tv Series", "tv", tv,
        newTitles: titles,
        header: switchHeader("tv"),
        personalized: true,
        overrideWidget: Icon(
          Icons.search,
          color: Colors.white,
          size: 32,
        )));
    tvTitles.add(new DrTextTransitionTitleObject("Movies", "movies", movies,
        newTitles: titles, paddingLeft: 35));
