Flutter 'Error running pod install' When I use 'flutter_barcode_scanner: ^1.0.1'

Question

When trying to run my flutter project I get:

Error running pod install

I've tried:

• flutter clean
• flutter upgrade

Everything in flutter doctor is good

iOS/Podfile: platform :ios, '9.0'

If I delete ' flutter_barcode_scanner: ^1.0.1 ' in pubspec.yaml it work so I think the problem from ' flutter_barcode_scanner: ^1.0.1 '

flutter run:

Launching lib/main.dart on iPhone1 in debug mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: 7CQFF4JBHQ

Answer 1

The plugin requires you to set your ios deployment target to 11

from the plugin's docs

iOS - Requires Swift support

Deployment target : 11

To solve this, open your Podfile at ios/Podfile and change the deployment target to 11.

change the second line of your Podfile from

# platform :ios, '9.0'

to

platform :ios, '11.0'

make sure it's not commented i.e there's no # in front of the line

In Flutter project, I Also faced with this issue. Fixed by doing those steps, (FYI- I used flutter_barcode_scanner: ^2.0.0)

1st step :- run this commands

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
flutter pub get

this can be do manually , go to ios/Podfile and delete Pods, Podfile and Podfile.lock. then run flutter pub get

2nd step :- using code editor, open your Podfile at ios/Podfile and change the # platform :ios, '9.0' to platform :ios, '12.0'

3rd step :- run this commands

cd ios
pod install
cd ..

4th step :- open your project in Xcode and change iOS Deployment Target to 12.1

5th step :-

Last Step :- Now you can run flutter build ios or flutter run
