App Bar Help
Hey everyone!​I want to integrate a similar app bar to the Khan Academy App in my own flutter application. I will have two pieces of text when the app bar is expanded, and then merge them when the bar is collapsed. Please let me know how I can achieve this.

Beginner -- Creating pages with distint variables
Beginner programmer here, Flutter/Dart is my first language. I am having trouble understanding what I think will be a simple concept. I am trying to create multiple pages of an app using a class as a template. Each page has several textfields where data will be entered. Each of these values will be used in calculations which are specfic to that page and output to variables. My problem is I need to access those off each page and keep them separate for later use. I can get the pages created and do the calculations. I can display those values and calculation results on the created page, but each subsequent page has the same variable name.​I apologize for such simple questions. I feel like I have turned the internet upside down, but I just don't know how to properly phrase a search to come up with anything worthwhile.

Beginner -- Moving data from one class to another
I am a brand new programmer so please excuse my ignorance. Flutter/Dart is my first language and the learning curve is steep. I'm still successfully climbing though.​I am stuck with accessing data from one class to another. I have a parent page and many child pages. I will enter data on the child pages, crunch some calculations on that data, and then display the data on the parent page. The parent page will display data from ALL the child pages. I initially thought using variables was the way to go, but today I read about ValueListenable and that intrigued me. My problem is I don't understand the steps of the ValueListenable process and how the ValueListenableBuilder, ValueNotifier, and ValueListenable all work together.​Is this the best way to move data from one class to another?

When should we extend an existing component instead of Stateless/StatefulWidget?
I realize Flutter was built with composition in mind. Nevertheless, I have seen many, many tutorials and examples where the author does something like this:

class CustomButton extends RaisedButton { final VoidCallback onPressed; final Widget child; const CustomButton({@required this.onPressed, this.child}) : super(onPressed: onPressed, child: child); @override Widget build() {} 

I have also seen many arguing that when customizing a widget such as RaisedButton we should instead create our own StatelessWidget and use the original widget as a child. So as a novice, I'm wondering if this is just a case of some people not following best practices or if there are instances where we would want to do one over the other. Does it matter?One thing I'm unsure about is that when composing a new widget that extends from StatelessWidget, we don't make a call to super(), which would seem to mean that we can no longer pass a normal RaisedButton's properties to CustomButtonunless we explicitly mark them in the constructor. Is this a correct observation?

! No devices available
Hi! I'm haiving some trouble with my phone, why I'd like to run flutter on only a virtual device. I've been working on this for days now with no success. Is it even possible? I'm using android studio, where I have created a new virtual device, but still it says "no device" when I run flutter.

In App paiement for a car park
Hi, Just starting a project with flutter and I am hitting a big wall. Let's say my app is to manage a car park. When a user parks he chose how long he will stay parked and then he pays. How am I supposed to proceed? Should I use Google pay? If so is there any flutter api to do so or should a build it native and use a platform to connect to it? Or can I use an external payment Api to make the payment?

User auth/login flow for different user types
Hi Everyone!​I am make Flutter app with Firebase backend to help people connect with DIY experts.Normal users can sign up using social auth.But need to verify experts are real experts. So when they apply we interview them and if they pass we sign them up. My idea is to enable email/password auth for these expert users. This way we can add them as user via Firebase console with email/password. Then update the database via console with the user details. In app will have separate login flow for experts - separate button for ‘experts’.I am not experience in develop app for two such different user types. I have not see any open source implement in Flutter. Any thought on my idea or any advice on better way?​Thanks!
