[app-to-app] Request permission failed after integrating flutter framework

💬 Questions and Help

I build iOS framework with command flutter build ios-framework, and my business contains Camera Permission Request. After the framework is integrated, the permission request failed. I know I can add config in Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
      '$(inherited)',
      #dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
      'PERMISSION_LOCATION=1',
      'PERMISSION_PHOTOS=1',
      'PERMISSION_CAMERA=1'
      ]
    end
  end
end

But if the flutter project is built as framework, it won't work, because it won't add the right macro such as PERMISSION_LOCATION=1 to the flutter target. What should I do?

I am having the same issue -> https://github.com/Baseflow/flutter-permission-handler/issues/956

I've labeled this as an enhancement. Related to https://github.com/Baseflow/flutter-permission-handler/issues/956 and https://github.com/Baseflow/flutter-permission-handler/issues/682

We've had some trials and errors, and finally made it. The key regarding add-to app is you must edit podfile in your existing ios app, not the one in the flutter module. Hope you guys have good luck.

[vanlooverenkoen]

We have done that as well, for us that doesn't work. 🤷

[jinsubkim-newin]

Could you try to edit podfile in the flutter module too? I've checked the code and found we added some source code of permissions in both of podfiles.

I have tried:

• updating podfile of the host app
• updating podfile of flutter module
• updating podfile of the host app & flutter module.

None of them worked for us

Same issue. I use Flutter Module Project to build iOS Frameworks, then add these frameworks to my Native iOS Example App, everything works fine except permission. When I call PermissionStatus status = await Permission.microphone.request();, I get a PermissionStatus.permanentlyDenied.

I find @jinsubkim-newin 's answer, and it works!

1. Add Privacy - Microphone Usage Description in Native iOS Example App's Info.plist

2. Find ".ios" folder(a hidden folder) in Flutter Module Project's folder. Open "Podfile" inside ".ios" and edit like this:

   post_install do |installer|
   installer.pods_project.targets.each do |target|
   flutter_additional_ios_build_settings(target)
   
   # flutter permission_handler required.
   target.build_configurations.each do |config|
     # Xcode 14.3 remove arc folder, need update deployment_target version.
     # ref: https://blog.csdn.net/crasowas/article/details/129901398.
     config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
     config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
     '$(inherited)',
     ## dart: PermissionGroup.microphone
     'PERMISSION_MICROPHONE=1',
     ]
   end
   end
   end

3. Flutter Module Project call flutter build ios-framework --output=framework/ to build iOS Frameworks.
4. Add these new frameworks to my Native iOS Example App, and works fine. System permission dialogue shows up when I first call PermissionStatus status = await Permission.microphone.request();

Hope this helps.
