Issues getting started 5.12.23 on iOS #48

Closed mikhael28 closed 1 year ago

mikhael28 commented 1 year ago

Hi there! I'm looking at using the another_brother package to integrate with Brother's printing SDKs - having some issues pop up, would love to post them here for others to potentially chime in. It's probably a pain, but my environment is sort of bleeding edge on the dependency side.

Steps to Reproduce:

  1. Fork the demo prime(https://github.com/CodeMinion/Demo-Another-Brother-Prime) and clone to local machine.
  2. cd into the repository, and clone the another brother repository directly into the codebase (with 0.0.34, which was just merged in a few hours ago).
  3. Run flutter pub get, which works just fine. Below is the output of transitive dependencies.

8. I updated the `permission_handler` library to 10.2.0 - and it worked! Build builds! Whether or not it prints I have no idea, because I don't have my printer, but the Android simulator booted the app! When I tried to print something, it asked for permissions to access files, and then it crashed. Here are the logs.

ANYWAYS, back to iOS :)

10. Well, same issue. I went ahead and opened XCode and updated the minimum distribution to iOS 11 for all the pods, as Flutter 3.10/XCode 14.3 require this. Same issue, but I'm pretty confident this step is necessary.
11. It seems that the issue is caused by the iOS simulators on Xcode, running on ARM, are somehow not supported - so, following someone's advice on SO I added an addition post_install hook in the Podfile. Full post_install code is below:

post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) target.build_configurations.each do |bc| bc.build_settings['ARCHS[sdk=iphonesimulator*]'] = uname -m end end end

12. This made some progress - the Xcode build built, but the iOS app was not built. Logs here:

(base) mikhael-cedar@Mikhaeks-MBP Demo-Another-Brother-Prime % flutter run Launching lib/main.dart on iPad Air (5th generation) in debug mode... Running pod install... 1,005ms Running Xcode build...

Error launching application on iPad Air (5th generation).

13. Running the build from XCode yielded a slightly different error

Undefined symbols for architecture arm64: "_OBJCCLASS$_BROTHERSDK", referenced from: objc-class-ref in TbStartCommunicationMethodCall.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

14. I then set the simulators to run on Rosetta, X64, and that works - however, i end up getting an error that it cannot find `another_brother`

Parse Issue (Xcode): Module 'another_brother' not found /Users/mikhael-cedar/Workspace/Demo-Another-Brother-Prime/ios/Runner/GeneratedPluginRegistrant.m:11:8

15. I ran flutter clean, but to no avail. Pod install shows the installation of another brother.

[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target Runner to Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig or include the Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig in your build configuration (Flutter/Release.xcconfig).


16. I changed another brother before the clean, to go back to pulling from the pub.dev package (0.0.33) instead of locally, as I thought that might be the solution. I think the issue at this point, is that XCode is still expecting another brother to come locally, isntead of remotely. 

Any thoughts on the last step?

Hi @mikhael28 ,

Thanks for reaching out and for the detailed info.

Here are a couple of things that might help:

Thanks again for reaching out. I hope this helps but don't hesitate to reach out if you still running into trouble.

mikhael28 commented 1 year ago

@CodeMinion so, my question is - how can I get around not building for iOS? Is the only option, that I will have to foresake the XCode simulator... forever? Is there a way to conditionally import fake Driver software, so that if I'm not actively using the APIs, that it will import dummy code/driver dependencies?

Because, I would imagine, most developers will not be okay with permanently giving up the Simulator UI.

Another question would be - why are we using the TypeB SDK? Looking at the compatibility list on their website, the ver4.x SDK seems to have much better support for iOS and Android - especially for the QL models, which are what I care about the most.

mikhael28 commented 1 year ago

Well, I've gone ahead and decided to have the app work on a physical device for now. @CodeMinion do you know when 0.0.34 will be merged into the pub.dev release? Also, is there going to be another hackathon this year?

CodeMinion commented 1 year ago

Hi @mikhael28 ,

Glad you got it working. I am currently waiting for some verification on some of the new printers we added (which I do not own) and if those clear we will be publishing to pub.dev soon after.

As for the hackathon I believe there will be, though you should reach out to Linus over Slack for more details. I chat with him from time to time over the slack from last year's hackathon.

mikhael28 commented 1 year ago

Great, ty! I don't have time to compete this year, but I'm happy to a demo to participants of some real world usage in the logistics/international freight space.
