cache消しとく

sudo rm -rf cache

そしたらいつも通りする

flutter pub upgrade
flutter pub get
flutter run

きちんとpod installする

出てくるエラー

Error output from CocoaPods:
↳

[!] Automatically assigning platform `iOS` with version `8.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies.
To update the CocoaPods specs, run:
  pod repo update

対処①

1.Go to /ios folder inside your Project.
2.Delete Podfile.lock
3.Run pod install --repo-update
4.Run flutter clean
5.Once complete, rebuild your Flutter application: flutter run

[!] CocoaPods could not find compatible versions for pod "sqflite":
  In Podfile:
    sqflite (from `.symlinks/plugins/sqflite/ios`)

Specs satisfying the `sqflite (from `.symlinks/plugins/sqflite/ios`)` dependency were found, but they required a higher minimum deployment target.

platform : ios, '13.0'にしてpod install 実行

podfile

# Uncomment this line to define a global platform for your project
platform :ios, '13.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.

対処③

ios>Flutter>Flutter.framework>Release.xcconfigで以下の２行を追加

#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig"
#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig"

Release.xcconfig

#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig"
#include "Generated.xcconfig"
#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.release.xcconfig"
#include "Pods/Target Support Files/Pods-Runner/Pods-Runner.profile.xcconfig"
