Build attempts to use ARC, which fails

[brianquinlan]

When building package:objective_c as a dependency of a Flutter plugin, I get:

ARC Restrictions (Xcode): ARC forbids explicit message send of 'dealloc'

Could not build the application for the simulator.
Error launching application on iPhone 15 Pro.

Adding

  s.requires_arc = []

to

pkgs/objective_c/ios/objective_c.podspec
pkgs/objective_c/macos/objective_c.podspec

fixes the issue for me.
