Ok, it seems like the documentation is not clear, you can use that widget inside your build method, like my example below, replace NewPage() widget by the widget you want use after user press 'continue'
class TestingPackage extends StatefulWidget {
#override
TestingPackageState createState() => TestingPackageState();
}
class TestingPackageState extends State<TestingPackage> {
double textScaleFactor = 1.0;
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: WhatsNewPage(
title: Text(
"What's New",
textScaleFactor: textScaleFactor,
textAlign: TextAlign.center,
style: TextStyle(
// Text Style Needed to Look like iOS 11
fontSize: 22.0,
fontWeight: FontWeight.bold,
),
),
buttonText: Text(
'Continue',
textScaleFactor: textScaleFactor,
style: TextStyle(
color: Colors.white,
),
),
// Create a List of WhatsNewItem for use in the Whats New Page
// Create as many as you need, it will be scrollable
items: <ListTile>[
ListTile(
leading: Icon(Icons.color_lens),
title: Text(
'Dark Theme',
textScaleFactor: textScaleFactor,
), //Title is the only Required Item
subtitle: Text(
'Black and grey theme (Tap to Change)',
textScaleFactor: textScaleFactor,
),
onTap: () {
// You Can Navigate to Locations in the App
Navigator.of(context).pushNamed("/settings");
},
),
ListTile(
leading: Icon(Icons.map),
title: Text(
'Google Maps',
textScaleFactor: textScaleFactor,
),
subtitle: Text(
'Open Address Links in Google Maps instead of Apple Maps (Tap to Change)',
textScaleFactor: textScaleFactor,
),
onTap: () {
// You Can Navigate to Locations in the App
Navigator.of(context).pushNamed("/settings");
},
),
ListTile(
leading: Icon(Icons.person_outline),
title: Text(
'Loan Contacts Enhancements',
textScaleFactor: textScaleFactor,
),
subtitle: Text(
'Updated look for faster navigation',
textScaleFactor: textScaleFactor,
),
onTap: () {
WhatsNewPage.showDetailPopUp(
context,
'Info',
"Navigate to any loan then select the bottom right icon to go to the contacts. You can press the dropdown arrow for contact information.",
);
},
),
], //Required
home:
NewPage(), // Where the Button will Navigate (Usually the Login or Home Screen)
showNow:
false, // Show now regarless of version change (Useful for showing from the main menu)
showOnVersionChange:
true, //Show only if the version changes or the user reinstalls the app
),
);
}
}
class NewPage extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Container(
child: Text("new page"),
),
);
}
}
