flutter upgrade to 3.3.8 from 2.10.5 , causing xcode Run error 'Flutter/Flutter.h' file not found

Question

when I upgrade flutter version to 3.3.8(stable latest version) from 2.10.5

VSCode Run and Xcode can't build both.

(error output can see Flutter Run at the bottom in detail)

---

Xcode version: Version 14.0 (14A309)

Flutter version: 3.3.8

---

already try

flutter clean -> flutter pub get

delete Podfile.lock -> pod install

like this fatal error: 'Flutter/Flutter.h' file not found in flutter

---

flutter run

Answer 1

I'm doing hybrid development, adding Flutter to an existing iOS project. It works fine in 3.0.3, but it doesn't work after upgrading to 3.3.8. I found the answer by comparing the differences between the two versions.

Version 3.0.3 is found in .ios/Flutter/podhelper.rb, and Flutter.xcframework is copied from flutter/bin/cache/artifacts/engine/ios-release's Flutter.xcframework to .ios/ Flutter/engine.

def install_flutter_engine_pod
   current_directory = File. expand_path('..', __FILE__)
   engine_dir = File. expand_path('engine', current_directory)
   framework_name = 'Flutter.xcframework'
   copied_engine = File.expand_path(framework_name, engine_dir)
   if !File.exist?(copied_engine)
     # Copy the debug engine to have something to link against if the xcode backend script has not run yet.
     # CocoaPods will not embed the framework on pod install (before any build phases can generate) if the dylib does not exist.
     release_framework_dir = File.join(flutter_root, 'bin', 'cache', 'artifacts', 'engine', 'ios-release')
     unless Dir. exist? (release_framework_dir)
       # iOS artifacts have not been downloaded.
       raise "#{release_framework_dir} must exist. Make sure "flutter precache --ios" has been run at least once"
     end
     FileUtils.cp_r(File.join(release_framework_dir, framework_name), engine_dir)
   end

The 3.3.8 version needs to execute the method in flutter/packages/flutter_tools/bin/podhelper.rb to link Flutter.xcframework. You can see this code in the flutter_additional_ios_build_settings method

# Skip other updates if it's not a Flutter plugin (transitive dependency).
next unless target.dependencies.any? { |dependency| dependency.name == 'Flutter' }

Then the answer is very clear, just add the flutter dependency to xxx.podspec of the error reporting component.

s.dependency 'Flutter'
