Specs satisfying the 'firebase_admob', but they required a higher minimum deployment target in Flutter

Question

My Flutter app has stopped working when updated firebase_admob to the newest version with firebase_admob: ^0.11.0+1, maybe it has a conflict between a package of the firebase. I'm trying to build an app for iOS but the flutter run fails because of cocoapods:

I'm just updating two packages of the firebase family to the newest version. The package I'm using:

firebase_admob: ^0.11.0+1
firebase_crashlytics: ^0.4.0+1

This is the output of pod install --repo-update

Updating local specs repositories

CocoaPods 1.10.1 is available.
To update use: `sudo gem install cocoapods`

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.10.1

I have some problems on my iOS device, while it's working perfectly on android. I'm getting an error on pod install

I've tried this using the flutter dev & master channel and have the same issue. I'm currently using master. I've tried removing my Pods folder and re-running pod install but not working anyone

This is the output of flutter doctor -v

Solution

To fix CocoaPods compatible versions

With the newer version of firebase sometimes need to run pod update manually, after that it generally found everything it needs to build.

To solve this issue follow the below command

1. Go to Your_Project_Directory/ios/
2. pod repo update
3. rm -f Podfile.lock
4. pod update
5. pod install
6. run flutter run

To fix required a higher minimum deployment target

You just need to update the iOS target in Xcode to at least 10.0. This was the reason for the version bump in all the FlutterFire packages. And Firebase admob works just fine on the latest versions.

BREAKING FEAT: forward port to firebase-ios-sdk v7.3.0.

• Due to this SDK upgrade, iOS 10 is now the minimum supported version by FlutterFire. Please update your build target version.

To fix it increasing your target version iOS target. To change your

Go to your flutter project. Navigate to ios and open  Podfile file and replace the second line of that file with this:

platform :ios, '12.0' or platform :ios, '10.0’ whatever you prefer of > 10
