Scroll Navigation Details

(It's recommended to set showAppBar = false on the Screen Widget)

navigationOnTop = True	navigationOnTop = False

Go to a Page Code

final navigationKey = GlobalKey<ScrollNavigationState>();

@override
Widget build(BuildContext context) {
  return ScrollNavigation(
    key: navigationKey,
    navigationOnTop = true, //Default is false
    pages: <Widget>[],
    navItems: <ScrollNavigationItem>[],
  );
}

void goToPage(int index) {
  navigationKey.currentState.goToPage(index);
}

Identifier Details

identifierPhysics = True	identifierPhysics = False

identifierOnBottom = False	showIdentifier = False

Code

return ScrollNavigation(
    showIdentifier = true,
    identifierPhysics = true,
    identifierOnBottom = true,
    pages: <Widget>[],
    navItems: <ScrollNavigationItem>[],
);

Hide AppBar on scroll.

return Screen(
    height: 56.0,
    elevation: 0.0,
    centerTitle: false,
    title: title("Title Scroll"),
    leftWidget: ScreenReturnButton(), //IMPORTANT TO RETURN!
    controllerToHideAppBar: controller,
    body: ListView.builder(
      itemCount: 15,
      controller: controller,
      itemBuilder: (context, key) {
        return Padding(
          padding: EdgeInsets.symmetric(vertical: 5),
          child: Container(
            height: 50,
            color: Colors.blue[50],
