Flutter iOS build failed when I run flutter run

Question

I have an issue with Flutter. I can't run my app on an iOS simulator and I can't build release for iOS. I get this error when I run app :

event sent after app closed: {id: 0, progressId: null, message: Running "flutter pub get" in Splitti...}
event sent after app closed: {id: 0, progressId: null, finished: true}
Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running pod install...
Running Xcode build...
Xcode build done.                                           41,3s
Failed to build iOS app
Error output from Xcode build:

I use flutter 1.22.5 version. How can I solve this issue, I have tried all the solutions but so far my problem is not solved.

Answer 1

First of all, My environment is windows 7 and laptop. But, you can think. In my opinion, you have to follow 'flutter doctor'

First, He recommended android licenses. you have to solve it. By use git bash here, command 'flutter doctor --android-licenses' and follow them.

If it isn't clear, it is another problem. maybe need to install java 8 on the net and Java development kit on the visual studio extensions and correct Path for JDK.

Second, ✗ Flutter plugin not installed; this adds Flutter specific functionality. ✗ Dart plugin not installed; this adds Dart specific functionality.

• on Android studio, you can find plugins. Search dart and install it. and then find flutter and install it.

if you solved all, all close them, re run android adv manager. and delete all device and remake device. you can run emulator. keep this emulator and close android studio, and open visual studio. it is better than android studio for flutter. If you open visual studio, you can use start debugging. you can see your project on emulator at visual studio like android emulator

Answer 2

1. Delete Podfile.lock
2. run pod install in iOS directory
3. Flutter clean && flutter run

You should be good to go.

Answer 3

use pod install in ios directory
