Error launching application on yueji的 iPhone.
It seems not FlutterWebView cause the problem, because I have many dependencies in my application, when I remove FlutterWebView and flutter run get the same error but with other library.
flutter doctor -v show this:

@Charles1198 Please check if you can run it on simulator. Can you please try if it's the same on master channel?
Seems similar to #38746
Charles1198 commentedon Oct 3, 2019
On simulator the same error but " Undefined symbols for architecture x86_64:"
Charles1198 commentedon Oct 3, 2019
There has no error 3 days age, I have published both android and iOS app successfully and not open the project until this morning. Today when I try to run the application again, it runs error. It is so weird.
Charles1198 commentedon Oct 5, 2019
Solved by check flutter channel from stable to master.
BondarenkoStas commentedon Oct 11, 2019
@timtraversy Can you please check if you having the issue on master? (to make sure it's the same issue). The fixes landed on master eventually will be in stable, that's the process of development. Hotfixes to stable are done only for some very severe cases, and in general not a good practice.
I understand your pain, and if you can't use dev and stable also blocks you, I can help to find the fix commits, so you can cherry-pick them into your stable.

Dont work from me...
My mac as High Sierra (10.13.6) and continue this error.
This project i created with flutter create name_project
BondarenkoStas commentedon Oct 29, 2019
@pedrobrasileiro You posted doctor with stable, if it doesn't work with master channel then probably there is another cause. Can you please file a new issue with that, including full error log (probably referencing this issue)? In this way things will be less messy and author won't be notified for nothing.

@nicowernli
I met this problem several times later, every time I can solve it by checkout to master channel and then checkout to stable channel. I know it is not the right solution but it works. Hope to help you.

Faced this error recently after upgrading from Flutter 1.9 to Flutter 1.12. Not sure if this is because of the Smartlook plugin or a general Flutter issue. Also, many times the Flutter run command succeeds on iOS emulator and fails other times. Also, I deleted the previous Podfile and let Flutter generate the new Podfile and new Podfile.lock.

flutter run -v: https://pastebin.com/t0G8rEnBError snippet:

The following steps work for me for M1 Mac:
1. Clean up
2. Get pods
3. Run the app (IMPORTANT: Running from Xcode might fail)
