プロジェクトを新しく作成、
libとpubspec.yamlのみ上書き

一回目のflutter run

Generating Pods project
Integrating client project
Pod installation complete! There are 4 dependencies from the Podfile and 20 total pods installed.
[!] CocoaPods did not set the base configuration of your project because your project already has a custom config set. In order for CocoaPods integration to work at all, please either set the base configurations of the target Runner
to Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig
or include the Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig
in your build configuration (Flutter/Release.xcconfig
).

無事ビルドできた!
