I'm trying to set up a build pipeline on Azure DevOps for my flutter project. The android build works but the iOS build is giving "fatal error: 'Flutter/Flutter.h' file not found".
This is my pipeline:
trigger:
- develop
pool:
vmImage: 'macOS-10.15'
steps:
- task: FlutterInstall@0
displayName: Install Flutter $(FLUTTER_VERSION)
inputs:
channel: 'stable'
version: 'custom'
customVersion: $(FLUTTER_VERSION)
- task: InstallAppleCertificate@2
displayName: Install Apple Certificate
inputs:
certSecureFile: $(APPLE_CERTIFICATE_FILE)
certPwd: '$(APPLE_CERTIFICATE_PASSWORD)'
keychain: 'temp'
- task: InstallAppleProvisioningProfile@1
displayName: Install Apple Provisioning Profile
inputs:
provisioningProfileLocation: 'secureFiles'
provProfileSecureFile: $(APPLE_PROVISIONINGPROFILE_FILE)
- bash: |
set -e ; set -o pipefail
$(FlutterToolPath)/flutter clean
$(FlutterToolPath)/flutter pub get
##################################
cd ios
pod install
xcodebuild -workspace Runner.xcworkspace -scheme dev -destination 'generic/platform=iOS'
cd ..
##################################
$(FlutterToolPath)/flutter build ios --flavor dev -t lib/main.dart --no-sound-null-safety # build breaks here
$(FlutterToolPath)/flutter build apk --flavor dev -t lib/main.dart --no-sound-null-safety
Here FLUTTER_VERSION is 2.0.5, and the certificate and provisioning files come from the Azure Pipelines Library. They are all found and the installation steps are working correctly.
Everything works until flutter build ios, which gives said error. I had the same issue a while ago on my MacBook Pro and I fixed it by opening the ios project with XCode and running Product => Build, the lines enclosed in hashes were added to mimic that behaviour but I'm not 100% sure they are correct.
What I tried:
- I tried adding the lines enclosed with hashes in an attempt to mimic the "Product => Build" XCode feature, which solved this issue on my MacBook Pro a while ago. This isn't working though, the build is fine but then the
flutter buildcommand fails with the same error. - I tried the solution proposed in the answer to this question, however it's not applicable in my scenario because these files are not pushed to the repository thus they don't actually exist
- I tried the solution proposed in the answer to this question but again, this file doesn't exist on the repository.
The weird thing here is that on the MacBook Pro I had this issue once and I resolved it with the "Product => Build" feature. I can easily build the iOS package on my MacBook so I'm thinking there might be some configuration in my MacBook that flutter/xcode aren't finding in the isolated pipeline environment.
