Flutter stuck on Building Dart code after doing flutter build ios

问题

I'm trying to build an archive by doing flutter build ios but I encounter a problem on Starting Xcode build

$ flutter build ios

Building com.example.example for the device (ios-release)...
Automatically signing iOS for device deployment using specified 
development team in Xcode project: XXXXXX
Running pod install...                                       
Starting Xcode build...
  ├─Building Dart code...     

I already build an archive one (last week) and it was working. Maybe this is due to flutter upgrade ?

$ flutter doctor

Doctor summary (to see all details, run flutter doctor -v):

en-GB)

That's an issue that was fixed very recently and the fix should already be available in the master channel.

flutter channel master
flutter doctor

You can also try dev channel, but I'm not sure if it landed there already.
The fix will of course be included in the next beta channel, but a beta release just came out last week, so it will probably take a while to the next.
