error: 'Flutter/Flutter.h' file not found when flutter run on iOS

1-Run flutter create (your project name). in the previous folder where you have your project(cd users/user/"projects_folder") (this will recreate your ios folder).

2-uncomment #platform :ios, '9.0' in the Podfile - i set that '10.0'

3-pod repo update

4-pod install

Flutter version on my mac was higher than the flutter version where I coded the application on… So I just downgraded my flutter to the version I coded on And tada Error resolved Make sure you are on the same version of flutter as the laptop you coded on In my case I coded it on old version of flutter on my windows laptop and tired to run on latest version of flutter so the error popped up. If this is your case then go through the below link - Flutter simulator error: Command PhaseScriptExecution failed with a nonzero exit code

If you only encounter this problem when running "flutter build ipa", in XCode make sure your Deployment Info under Runner and Pods matches the 'platform' in ios/Podfile.

This happened me too. After follow below steps problem sorted for me !

1. Back up the Runner folder in your ios folder to a safe place.
2. Delete the ios folder:
3. Go to the root directory, run the following command:

flutter create .

4. After above step, will create ios folder. Copy and paste the Runner folder you have backed up before to the new ios folder:
5. Run the project in android studio or VS code
6. Navigate to your ios folder and run:

pod install

7. ios > Runner.xcworkspace right click and Flutter > Open iOS module in xCode

It will work :)

1. Copy info.plist, Assets.xcassets and other important files.
2. Create a New project with same name and bundle id.
3. Add an iOS project in your old project and add 1st step information in that.
4. Run project. It's working now.

I found a simple solution. just in case save backup :)

1. rm -rf ios
2. flutter create -i swift .

That's it.

In my case I had modified my Run Script (in Targets - Runner - Build Phases) to add Crashlytics. Actually we should create a new Run Script for Crashlytics. My answer should also work for those who removed or mispositioned their Run Script:

Make sure the Run Script is between Check Pods Manifest.lock and Compile Sources :
the contents of the script should be :

 /bin/sh "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build 

inside the Shell (/bin/sh).

While writing this answer, the Run Script for the latest version of Crashlytics should be at the last.

A really simple solution that worked for me was simply: close the xcode project. Then, on Android Studio, build the iOS archive by going to Build -> Flutter -> Build iOS. Then reopen the xcode project and it built and ran fine.

The error "No such module 'Flutter'" typically occurs when the Flutter framework is not properly linked or recognized by your iOS project. This can happen for several reasons, such as a corrupted installation or issues with the project configuration.

To resolve this error, you can simply reinstall Flutter. Here are the steps to do that:

1. Uninstall Flutter:

• Delete the Flutter SDK folder from your system.

2. Download the Latest Flutter SDK:

• Go to the official Flutter website: flutter.dev.
• Download the latest stable version of the Flutter SDK for your operating system.

3. Extract and Set Up Flutter:

• Extract the downloaded file to your desired location.
• Add the Flutter bin directory to your system's PATH.

4. Run Flutter Doctor:

• Open a terminal and run flutter doctor to check for any issues and make sure everything is set up correctly.

5. Reopen Your Project: Open your Flutter project in your IDE (like Xcode or Android Studio) and ensure that the project is configured to use the newly installed Flutter SDK.

By following these steps, you should resolve the "No such module 'Flutter'" error and be able to build your project successfully.

worked for me;

Xcode => Runner => Build Settings and put "Allow Non-modular Includes In Framework Modules" to "yes"

I spent some time on this. It turned out the problem was the order of some statements in the podfile -> post_install do |installer|

Specifically

flutter_additional_macos_build_settings(target) 

MUST come last and not first.

Here is that working section in my podfile. The first 2 loops are specific to libraries I am using in my project, but notice I put the statement added by Flutter last:

post_install do |installer| installer.pods_project.targets.each do |target| if target.name == 'webcrypto' target.source_build_phase.files.each do |file| if file.settings && file.settings['COMPILER_FLAGS'] flags = file.settings['COMPILER_FLAGS'].split flags.reject! { |flag| flag == '-GCC_WARN_INHIBIT_ALL_WARNINGS' } file.settings['COMPILER_FLAGS'] = flags.join(' ') end end end if target.name == 'webcrypto' || target.name == 'super_native_extensions' || target.name == 'printing' || target.name == 'irondash_engine_context' || target.name == 'cryptography_flutter' || target.name == 'PromisesObjC-FBLPromises_Privacy' || target.name == 'PromisesObjC' target.build_configurations.each do |config| config.build_settings['MACOSX_DEPLOYMENT_TARGET'] = '12.4' end end #This MUST come last otherwise the build will fail with 'FlutterMacOS/FlutterMacOS.h' file not found flutter_additional_macos_build_settings(target) end end 

If this was your problem then update your podfile, delete the Pods directory and the podfile.lock file, then run flutter pub get and rebuild. Good luck.

flutter pub cache repair 

this worked for me
