Hey, great content! Another use-case for flavors in flutter: "We need app for 2 markets: global and china (use different auth, payment, notification methods), so we did it with flavors". Thank you.
Like without even watching! I'll add it to my watchlater playlist and get back to it when I have time for it to watch without interruptions. Thanks for great topic! More comments later.
@@FlutterExplained That being said, I noticed something strange for the iOS part: when you go to Runner.xcodeproj, then Targets, then Build Settings, then go to the User-Defined part, the FLUTTER_TARGET setting always has the same value, regardless of the scheme... Is it normal?
@@matthieuregnauld9648 To be honest, I do not know :), I checked two of my projects and at least for my examples that is correct it looks normal to me :)
This video has been my go to any time I start a new project. I have a question - I notice you use schema for creating the flavours. I saw a friend use target in React Native. My question is what is can you do the same for flutter. I think so because I have read a medium post where some use it. What is the benefit of using target or schema.
Very good question. In Xcode, a "target" specifies what to build and includes all necessary files and settings, while a "scheme" defines how to build, run, and manage the workflow for one or more targets.
I dont get it why do we have to create 3 separate files for `main_dev, ,main_stg, main_prod`. If there is already a launch.json that can target one `main.dart` ???
Excellent explanation, When I upgraded my Rivier pod library to the latest version, during the runtime I got this error Class 'FlavorConfig' has no instance getter 'state'. Receiver: Instance of 'FlavorConfig' Tried calling: state. Can you help me with what I'm supposed to do here? I really appreciate any help you can provide.
Hi Stefaan, thank you :). Regarding your question I am not sure, it could be possible but it will be very challenging like iOS development is in general. But you can skip the iOS part and just set it up for Android.
Great video! I have one question: if I have 5 flavors, for example, where each one have a list of assets. All the 5 app builds will have all the 5 list of assets, resulting in a build with unused assets, whereas I need only one.
That is correct, it will bundle all the assets that you define in the pubspec.yaml and maybe also a very interesting downside of Flavours. I do unfortunatly have not so much experience to tell you if there is a way to improve the treeshaking in that area, but it is worth investigating!
Hi Cleo, very good question. Probably you would need a build runner that generates the constant file with the flavor name. Another option would be to make the file a none constant file. I hope that helps you :).
Hi Andres, this is a really good question and I am not absolutely sure if this is possible. I will have a look and if I find a solution I will let you know.
Flutter Flavors are an exciting topic because you can create multiple apps right out of one codebase. Additionally, it allows you to manage different stages of Development with them like Dev, Testing and Production. If you have any questions, please feel free to write them right below.

Hi there, that sounds like a very weird error, but you do usually not want to open the android folder, you want to be in the parent folder to build the project. it searches for "lib/main.dart" inside of the android folder probably. But it is hard to analyse the problem without the correct error log.
@@FlutterExplained OH, when i generate apk or aab, i alway open file android inside project to build.Because i want build by android studio tool, not terminal. But when i build this error arrive.
That is because it searches for a different entry point if you rename the main.dart file. One solution is to work then via the cmd stackoverflow.com/a/58514075/3690032 Another solution would be to find out how to set the correct Entrypoint in Android Studio.
Hey, how can i delete a scheme? i created 3 but now i'm gonna use just 2, prod and qa. Since when I deleted the "main_dev.dart" file i can't build the app, got this error "error when reading "lib/main_dev.dart""
Hi I hope I understand you correctly, then you need to change your Android Studio executable or your cmd line. Around 8:06 I explain that part. That should solve your problem inside of Flutter if you want to remove a scheme in XCode you will need to do it there.
Hi thank you for your video! I would like to know if you or someone Know a different way to do it, because in my case I need to build over than 30 apps for each operation system. So, I need some an easy way….
Nice video mate, I see you left Runner as well so I have duplicated the same I have dev, live and Runner (which is the same as live). I do have a problem with Firebase TestLab and integration testing, maybe you can help. Before the flavors was working fine (and on android after flavors works fine as well, but not on iOS). If I run flutter drive --driver=test_driver/integration_driver.dart --target=integration_test/app_test.dart works fine -> routing to Runner flavor if nothing is mentioned But flutter build ios integration_test/app_test.dart --release and then xcodebuild -workspace Runner.xcworkspace -scheme Runner -config Flutter/Release.xcconfig -derivedDataPath $output -sdk iphoneos build-for-testing Fails some tests. Any idea how these flavors and integration testing and TestLab fit in all together?
Hi there, great video! Was just wondering at min 5:00, what's the advantage of using cascade operator after instanciating the class to set the properties values rather than populating them straight in the constructor? Is it just a matter of readability or its more performant? Thanks for the video
Great video i have followed all the config but when i run in ios i am getting below error. acn anybody please tell what i am missing or any help would be appreciate. Thanks Error: Error when reading 'lib/main.dart': No such file or directory
I used to implement flavors in a very rudimentary manner...this is much more intuitive. You sir, have a new subscriber.
Awesome, thank you!
Wow this helps a lot! I like Max's youtube because he understands what we need to know for making a production-level application.
Thank you so much for your feedback. :)

7:15 Why do you not use the "Build flavor" textfield in Android Studio (under Additional attach args)?
I did not know about that :) thanks for the suggestion!
Thanks, very usefull!!!
Glad it was helpful!
Nicely done
thanks so much, you help me a lot
Great Thanx 👍
Is this method still recommended in 2022 with flutter 3.0?
is there a way to flavor a package/plugin?
Great topic, not enough information out there about it!
Thank you for your feedback. That was exactly the issue I had and why I thought a video would be helpful.
How can I use a theme like i need to set the Elevated Button background color of its primary color.
I dont get it why do we have to create 3 separate files for `main_dev, ,main_stg, main_prod`. If there is already a launch.json that can target one `main.dart` ???

Could you tell me how to use the apiEndpoint without context? I need to call it in file where I keep the constants for the API url.
Hi Cleo, very good question. Probably you would need a build runner that generates the constant file with the flavor name. Another option would be to make the file a none constant file. I hope that helps you :).
How can you debug through android studio when running your app through a flavor command? It does not seem to be possible.
is there any approach where we can get --flavor argument in main() without defining any folder scheme , just in main.dart
Awesome tutorial. But unfortunately I am not able generate ios build. Can you please guid me what extra we can do to generate ios build from xcode
Common thing is google services file from Firebase, and how to apply flavor wise google services files into the source code would be helpful.
ok so how about firebase and Google map api?
Thanks.
how can i use flavors for macos ?

AFAIK we changed the filename of main.dart to something else could you try to change the config file name of the file to the correct name.
