flutter project not running on ios

Question

Have a previously running app that is no longer running and I have been trying to work this out for weeks. Have got it to a point now where it almost runs but I get the following issues at the last hurdle:

flutter run -v

This appears to successfully build the app and launch it, the screen briefly goes white and then the app closes. The last entries from the terminal output is:

And the issue looks different in Xcode (although is quite likely exactly the same issue). Looks like maybe a memory leak? I am not sure how to read this information. I get an error appearing that looks like this:

io.flutter.204.ui (625): signal SIGABRT

And then in the logs beneath I have:

Thousands of times until it runs out of memory, but I am not quite sure what this is, or how to begin trying to resolve it.

could you share your whole project with us so we can debug on it by trial and error? — Edin, Apr 04 '20 at 08:25
I don't think that's going to be possible, xxx. It is an app already fully functional and published on the Android Store. I am just trying to publish the same application through Xcode into the Apple store now. Apologies. Is there no troubleshooting steps you are aware of that I could use to help narrow down the cause of this? — Bisclavret, Apr 04 '20 at 14:17
ok but could you post the output from the flutter doctor please? — Edin, Apr 05 '20 at 12:23
Is this happening after integrating firebase into your app? If yes, then have you followed the steps mentioned on the pub page correctly? — RoyalGriffin, Apr 06 '20 at 20:33
does the install work if you go into the project folder with the terminal and run: flutter build ios? — Edin, Apr 07 '20 at 08:44
Do you have developer account? If it is an iOS 13.3.1 then you need to have a developer account to run it on a real device. https://github.com/flutter/flutter/issues/49693 . Have you tried to run it on a simulator? — Zeynal, Apr 07 '20 at 09:57
@Bisclavret You might need to specify a build version. I added code and a link in my answer. — aldobaie, Apr 11 '20 at 22:15

This is still a problem. `flutter clean` and `pod deintegrate` don't work. They are useless, even though issue is probably with pods, but, no idea why it doesn't work on debug mode. `flutter build ios` is successful, but, it doesn't run. Then, I have to go to Xcode and run project from there. That way, it works, but, hot reload deosn't work. Flutter is just annoying. — Karanveer Singh, Oct 15 '21 at 08:24

Steps To Take

Update Xcode and macOS.
Open Xcode and download/install simulators.
From the Flutter app directory, open ios/Runner.xcworkspace in Xcode and select a development Team under Signing & Capabilities.
Follow these instructions: https://flutter.dev/docs/development/ios-project-migration
Then run in the terminal in your project folder:

flutter clean && flutter build ios && flutter run

Continue Only If It Still Doesn't Work!

6a) If above doesn't work and you are using git or another source control, then I committed everything and pushed it up. Then, I deleted the folder, git fetched it again and everything worked normally.

6b) Another solution is to remove all pods:

Delete the Pods folder and the `Podfile.lock` file.

and then rebuild the pods and the project with the following commands from your projects folder in the terminal:

cd ios && pod deintegrate && cd ..
flutter clean && flutter build ios

Hi @Hannes Sverrisson. I managed to follow through your advice exactly as listed in your answer. At the part where it states "flutter build ios" I get a critical error: "fatal error: too many error emitted, stopping now [-ferror-limit=] 1 warning and 20 errors generated." I will post the output of this in my original question so that you can see. – Bisclavret Apr 13 '20 at 04:04
@Bisclavret, this new error message is quite different, thus, I have added the the step 6b for you depending on these new errors that you have added, if step 6a was not possible (you didn't clarify if you did git clone again) then this should help your build. – Sverrisson Apr 13 '20 at 14:13
Thank you Hannes. After trying your 6b step, the flutter build ios now completes successfully (or at least it claims to). After trying flutter run -v again, I am right back to the start of this issue: [+5026 ms] mDNS lookup failed, attempting fallback to reading device log. [ ] Waiting for observatory port. So while it has possibly done some stuff, it hasn't had any effect on the original issue at all, unfortunately. Appreciate all of your time though. I would love any further suggestions. – Bisclavret Apr 14 '20 at 13:53
One thing I have noticed, not sure if it helps at all, is my ios/Frameworks folder is totally empty. In Xcodes debugging it looks for files in here over and over again until it crashes. Are there supposed to be files in this folder? If so, why wouldn't I have any? Thanks again. – Bisclavret Apr 14 '20 at 13:54
@Bisclavret there should be Runner.pods there at minimum, but it appears if you can build, ios/Frameworks folder. Delete the Pods folder and Podfile.lock file. After that run: "flutter build ios" again. If this doesn't work push the code into git and do solution 6a. – Sverrisson Apr 14 '20 at 19:54
I have already deleted the pods folder and the lockfile, as I mentioned previously, as this was your 6b solution. I'll try set up a git account later today and push/pull it into there. Not sure how this can help as it is just going to leave the code base exactly the same. I think you mentioning that I should have files in my ios/Frameworks folder is very likely the issue here. Any idea what can cause this? – Bisclavret Apr 14 '20 at 23:44
@Bisclavret the code in that folder is made when you build, but you are not able to that's why they are empty. The Git account helps because the problem is not with your code and it will just save your code files but you will make a new Flutter build project. – Sverrisson Apr 15 '20 at 10:55
If I make a brand new build and try to pull my repo down again, will I still have to go through the painful process of setting up all the xcode config settings again? All those build settings etc.... I spent more time on all that junk than I did writing the entire app. Or does it pull all that information as well? – Bisclavret Apr 15 '20 at 12:55
@Bisclavret it stores all your config also and if you get into problems again you can always pull code fresh from Github. You can make a free account and your code is accessible always from all computers – Sverrisson Apr 15 '20 at 13:02
Hi Hannes, thanks again for your continued feedback. I created a new git repo and pushed everything up. I then renamed my old project and created a new one with "flutter create app_name". I then moved into this folder and pulled my repo down into it. I verified that the files had transferred over, all looks good. I ran "flutter run -v" in this new project and got the exact same error: mDNS lookup failed, attempting fallback to reading device log. Waiting for observatory port. – Bisclavret Apr 15 '20 at 13:49
I have also added another edit to the question, with output of a build failure in xcode when I try and run the application from there. – Bisclavret Apr 15 '20 at 14:09
@Bisclavret it looks like you need do step 3, to set your Team in Signing & Capabilities in Xcode. Also are you building a release instead of debug? What command did you use for running. – Sverrisson Apr 15 '20 at 15:01
Hi Hannes. According to my settings, my signing is already set up. Is it possible for me to do this wrong such that it breaks the app? It also lists my signing certificate along with the signing code for that certificate. Could it be the wrong one? For running the application I generally just use flutter run -v, or in xcode I just open the xcworkspace file and hit the run button, targetting my iphone. – Bisclavret Apr 16 '20 at 12:29
@Bisclavret it's very hard for me to answer these questions without seeing all. Now that you have pushed the code to Github you can send me a private message with the path to the source and I can try to build the code on my side, unless it's proprietary. – Sverrisson Apr 16 '20 at 12:50
Oh man, that would be absolutely amazing if you could take a quick look. I have gone to your profile but can't see any way to message you on there. How do I get in touch with you? – Bisclavret Apr 16 '20 at 13:15

I had a similar issue. I downloaded a Flutter sample, and it kept crashing after a brief white screen without any understandable errors. I finally found that some of the codes or packages were depending on newer version of Flutter than the stable version.

In the terminal type:

flutter channel

see what is your current channel, then you can try master or beta channels:

flutter channel master
flutter upgrade

See if this helps!

Also check this suggested solution: https://github.com/flutter/flutter/issues/29286

You need to run
flutter build ios --debug (or --profile or --release) 
flutter run --release
before you launch the project in Xcode.

@bisclavret I updated the answer with a link to a suggested solution. see if that would solve your problem. – aldobaie Apr 11 '20 at 22:14
Hi aldobaie. I appreciate you taking the time to post a suggestion, but updating flutter is an absolute no-go. Absolute last resort after ruling out every other possible fix. The reason is that flutter development is awful, and every single time I have updated flutter so far, it has critically broken every single application in my suite, often taking weeks or months of full-time work to fix. You can see my thread here: https://github.com/flutter/flutter/issues/54088 a flutter dev has suggested I do this and I cloned my system to humour him. The disastrous results are posted there. – Bisclavret Apr 13 '20 at 02:47
This solution worked for me. – Onur Kağan Aldemir Jul 16 '21 at 23:25

There doesnt seem to be enough information right now for us to fix your issue, but from the flutter doctor it may be a problem with the flutter SDK version you are using as it is 7 months old and you are using a new version of xcode to build the project. It looks like there were problems similar to what you are having related to that version of the SDK. Reference

So first, try updating your flutter sdk with flutter upgrade

Please update the flutter doctor and the output of your latest debug run when you have updated so we can try and help you further.

Also, can you try running it on a simulated iOS device as well as an external device to see if it may be a problem with how the xcode project is configured to build?

Hi Jwildsmith, thank you for your reply but I will refer you to my comments above that you should never, ever allow any updates to flutter. The backend development is too unstable and just.... poor. Results of upgrading are posted in this thread: https://github.com/flutter/flutter/issues/54088 – Bisclavret Apr 13 '20 at 03:01
With regards to the information side, is there any tools I can use to find the source of this memory leak? Like something must be trying to do this, somewhere: Failed to find snapshot: /private/var/containers/Bundle/Application/E00E6D3690/Runner.app/Frameworks/App.framework/flutter_assets/kernel_blob.bin ... is there anything I can use to find out what is trying to do this? The developers of this platform would absolutely know what is doing this. Otherwise what are they even doing. – Bisclavret Apr 13 '20 at 03:14

I was also getting this error but after installing latest version of android studio this has been gone.I think this is occuring by system not manually. you also should try it.

Hi mate. This is for ios. It's Xcode. There are no issues in this application on my windows machine running Android Studio. The app has been published on the android store for a year now. – Bisclavret Apr 13 '20 at 02:59
Do you know what Android Studio is? It's a coding platform like VSCode. With Flutter apps, a lot of us prefer using Android Studio, and you can run the app on iOS from ANdroid Studio. – Globe Oct 16 '22 at 04:46
