I can't run my Flutter app on my iOS emulator at all and I've looked at similar posts to no avail. Any pointers on what to do? Or any other communities I can try getting help from? Thanks!
Due to a breaking change made by https://github.com/flutter/flutter/pull/58635, you can upgrade flutter_svg to 0.18.0 or downgrade flutter otherwise.
upgrade your flutter_svg plugin to
flutter_svg: ^0.19.0
Since this morning, the generation step of built value (pub run build_runner build) is failing with
[SEVERE] built_value_generator:built_value on lib/client.dart (cached):
Unknown error in BuiltValueGenerator for myproject|lib/client.dart.
NoSuchMethodError: The method 'getParsedLibraryByElement' was called on null.
Receiver: null
Tried calling: getParsedLibraryByElement(Instance of 'LibraryElementImpl')
I tried upgrading to built value 6.6.0 (from 6.3.2), but it didn't help
Dart version is 2.1.0-dev.9.4
Any suggestions are welcome

This plugin was migrated from using the deprecated Android Support Library to AndroidX. If your project was migrated to use it as well you should install version 4.X.X of the plugin. If you are using the old project structure please use version 2.4.11
Had the same problem.
tried to migrate to AndroidX using this method as suggested by flutter documentation :
1.tried menu Refactor > Migrate to AndroidX
2.got "No usages found"
I still had the error , so i tried the solution in this link (using the selected answer) :
[Flutter Projects & Android X Migration Issues
And it worked perfectly
Running dartanalyzer on this snipped found on flutter.io/get-started/codelab yields these errors:

$ dartanalyzer --version
dartanalyzer version 1.24.3
What can I do to make the analyzer run correct?
For Flutter projects instead of running dartanalyzer you should run flutter analyze. Flutter ships with it's own SDK, so the regular dart analyzer doesn't work without some extra configuration - which that command provides.

I got this issue resolved. It was because jar version mismatch. I was using jRules Studio version 7.1.1 and was executing using jRules version 7.0.0 jars .
I modified my classpath to use version 7.1.1 jars for jRules version 7.1.1 rule studio.
