Changing bundle id on flutter ios app for debug, staging, release builds

[Jason Scott]

I'd like to be able to have a different bundle id for my debug, staging and release builds. This is quite easy to setup in Xcode and I can use a new Scheme for each (see examples in this blog post https://medium.com/@danielgalasko/run-multiple-versions-of-your-app-on-the-same-device-using-xcode-configurations-1fd3a220c608).

But I can never get it to play well with flutter. When I select the Scheme for "staging" for example and then Archive I get all sort so of build errors. Prior to doing this I need to `run flutter build ios` but it uses the release scheme by the looks of its.

Its all very confusing so am wondering if anyone has a clear and concise guide on how to do this with flutter..?

Flutter CLI tools 'run' and 'build' take a '--flavor' argument that maps to schemes on iOS.

So `flutter build ios --flavor "MyScheme" ' will work? Trying now...  ;-)

Then after running that I can perform an Archive in Xcode - is that the normal process?

[Mikkel Ravn]

... though the build flavor does not change the fact that Flutter tooling expects you to have debug, profile, release builds. They do add a second dimension though, as in a "free" vs "paid" flavor of your app.

The intention of build flavors is documented here: https://github.com/flutter/flutter/pull/11734

I just managed to get the app archive to work even though I just ran `flutter build io` (which is a release build). Lots of magic here.  ;-)

@Mikkel - thanks for the link - trying to digest it now.

It seems to break when I switch back to the normal Runner Scheme. Back in the flutter dev tools I get this error when trying to run the app: 

Launching lib/main.dart on iPhone X in debug mode...

Running pod install...

Starting Xcode build...

Xcode build done.

Seems that those two errors above was just to restart the ios sim. Not sure why it gets it knickers into a knot after having previously changed xcode scheme's....

[Jason Scott]

Following this issue it looks like what I am trying to do (different bundle id's for different Schemes) is not supported by flutter...

https://github.com/flutter/flutter/issues/15567

That seems to be a big issue for using Flutter in real-life situations. Any ways around this?

I think you have two options to do that:

1st with Xcode configurations. Flutter select the configuration with the
--flavor flag
2nd if you don't want to use configurations you can build your project
with Fastlane gym where you can specify which Scheme you want to build

Thanks for that info Ralph. I still can’t see how you can change the bundle id’s but I need to read this about ten times for it to start sinking in. ;-)

[Jason Scott]

Maybe you’re supposed to keep the same bundle id but just change the icon etc like in that blog post.

[Ralph Bergmann]

I created a new configuration (duplicate a existing one) and named it
"foo". Then select the target -> Build Settings -> Product Bundle
Identifier and change what ever youe need.

If you do that then try and go back to normal flutter development the flutter tooling gets confused about the multiple bundle id’s. There’s an outstanding issue about it I linked earlier.

[Jason Scott]

I followed the blog post on using flutter flavors but `flutter buid ios --flavor <flavor>` causes heaps of xcode build errors such as:

Unable to find the Gerenated.xcconfig include, and

diff: /Podfile.lock: No such file or directory
diff: /Manifest.lock: No such file or directory
error: The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation

Running pod install as the error mention doesn't fix things.

Seems that there's other config that needs to be done to get flutter build to work with flavors on ios which is mentioned in the blog post.
