GoogleMaps 3.10.0 podspec was published at the same time.
https://github.com/CocoaPods/Specs/blob/master/Specs/a/d/d/GoogleMaps/3.10.0/GoogleMaps.podspec.json

[jmagman]

I'm actually not sure how this happens. google_maps_flutter pub version is at 0.5.29 and GoogleMaps CocoaPods is at 3.10.0:
https://cirrus-ci.com/task/5509800735801344?command=main#L2220

[module_test_ios] [STDOUT]   google_maps_flutter:
[module_test_ios] [STDOUT]     dependency: "direct main"
[module_test_ios] [STDOUT]     description:
[module_test_ios] [STDOUT]       name: google_maps_flutter
[module_test_ios] [STDOUT]       url: "https://pub.dartlang.org"
[module_test_ios] [STDOUT]     source: hosted
[module_test_ios] [STDOUT]     version: "0.5.29"

[module_test_ios] [STDOUT]   - GoogleMaps (3.10.0):
[module_test_ios] [STDOUT]     - GoogleMaps/Maps (= 3.10.0)

However locally when I try to force this combination locally I get this error, which the test doesn't show:

[!] CocoaPods could not find compatible versions for pod "GoogleMaps":
  In Podfile:
    google_maps_flutter (from `.symlinks/plugins/google_maps_flutter/ios`) was resolved to 0.0.1, which depends on
      GoogleMaps (= 3.10.0)

Specs satisfying the `GoogleMaps (= 3.10.0)` dependency were found, but they required a higher minimum deployment target.

And that makes sense, because google_maps_flutter minimum version is iOS 8.0 and GoogleMaps 3.10 is iOS 9.0.
GoogleMaps 2.7.0 is the last version to have a minimum of 8.0:.

I think the right thing to do it change the podspec to s.dependency 'GoogleMaps', '~> 2.7' until that minimum version is increased to 9.0.

Not sure why this started happening as soon as GoogleMaps 3.10.0 was published.

I have never seen this error before, I'm not touching podspecs (only the fake ones for web components). Odd.

I think the right thing to do it change the podspec to s.dependency 'GoogleMaps', '~> 2.7' until that minimum version is increased to 9.0.

Sounds right, I'm trying to find other similar builds to see which version of GoogleMaps they're grabbing. (There's been 3.0.x versions for as long as 2.7.x, according to the CocoaPods link)

I think there are similarly-failing checks in flutter/plugins, with the Camera plugin:

Have iOS 8 and 9 died suddenly? :/

@ditman That's warning is an old issue #20708 (comment).
Why is camera trying to call GoogleMaps code?
