White label app - exclude other flavors(schemes) during build time
Let's say I want to write a white label app which will describe my application - for example main view is AVIEW. Then I want to have different flavors(schemes) which will have their implementations of AVIEW in specific directories. The case is that if I build target#1 I don't want to have implementations from target#2, #3 etc. included. How can I achieve that?

What are the common problems you are facing while developing apps with Flutter? Problems may include issues with ide, libraries etc.
I am going to list common problems I face daily. My problems are mostly with the toolings. I mostly use Vs code, I don't if these problems exist in Android studio or xcode. This is not a support or help post, because I have already tries most of the solutions mentioned in github and SO.Vs code sometimes builds old code and hot restart/reload don't work properly.I have to do flutter clean too often due to 1.Analyzer terminates every time after flutter clean and sometimes when a build is complete.When the codebase gets bigger then constant termination of analyzer means you have no auto complete, errors/warnings while the analyzer restarts.While debugging using breakpoints, hot restart does not work and gets stucks on syncing files.Lack of audio libarary support from the flutter team. I was working on an audio streaming app, there is not a single library which plays both local and remote audio files, plays in background, have notifications and lock screen controls in both android and ios. When we ended up doing is using multiple plugins to achieve this. For someone who doesn't have great knowledge of both native platforms, this makes getting this done harder and wait for the community to implement features.The problems listed above are already have issues in github and threads in SO. I just want to know if you are facing similar issues. If not what are the other problems you are facing.

Is it viable to use Flutter without using Material or Cupertino?
My application has a unified design, not specifically inspired by Material or Cupertino design patterns.I'm hesitating between 2 approaches: - Using material (the most advanced and polished package) and twisting the widgets and the theme to "unmaterialize" it, - Only using the unopinionated package widgets.The later makes more sense to me, but at the time I have serious doubts about the viability of the solution. When asking about using Flutter without Material (like here), people are like "Yeaaah sure! It is technically possible, do whatever you want". But I found literally zero feedback about going to production with this approach.The only useful "neutral" widget I found is WidgetsApp it just wires up the navigation stuff and that's it. There is no Scaffold, no theme inheritance mecanism...Other example: I have a drawer in my app. AFAIK, a drawer not a material thing, however in Flutter, it is a widget from the material package. So what should I do? Implement my own?Are there people out there who doesn't use Material or Cupertino? I mean, for real?

Purchasing a physical Android device for testing.
I'm an iPhone guy and don't see myself switching any time soon, but wanted to start testing on a physical device. I've found some imei blocked android devices on my local craigslist and was wondering if that was a smart purchase.It says it basically can't be activated on any carrier, which I don't imagine I would need. It's about 50% of the normal used price.Is there something I'm not thinking about?

👉You can specify whether your Flutter project uses Swift, Objective C, Kotlin, or Java by specifying:

"--ios-language objc" or "--android-language java" when you type "flutter create".

💡By default new projects use Kotlin and Swift.— Flutter (@FlutterDev) April 17, 2020
