No such module 'google_mobile_ads' in iOS native code(Flutter plugin)

[andj207]

Plugin Version

google_mobile_ads: ^1.3.0

Steps to Reproduce

I create a Flutter plugin for Admob to reuse in my different projects for banner, interstitial, native ad and rewarded ads. I create it so that I can just add the plugin to other project's pubspec.yaml and use without recode or copy/paste every time.

It works fine on Android native code, the "google_mobile_ads" sdk is recognized and can be accessed without adding any dependency.

But, the problem is that the google_mobile_ads is not recognized in my iOS code (to create the Native Ad Factory) when Run Build in Xcode. When I use "Ctrl + Click" the "FLTNativeAdFactory" class to "Jump to Definition" in Xcode, it works but the build fail with the error. See the attached image.

Here is my code and setup:

• admob_ads plugin pubspec.yaml
  

• the ios code podspec

Pod::Spec.new do |s|
  s.name             = 'admob_ads'
  s.version          = '0.0.1'
  s.summary          = 'A new Flutter plugin project.'
  s.description      = <<-DESC
A new Flutter plugin project.
                       DESC
  s.homepage         = 'http://example.com'
  s.license          = { :file => '../LICENSE' }
  s.author           = { 'Your Company' => 'email@example.com' }
  s.source           = { :path => '.' }
  s.source_files = 'Classes/**/*'
  s.dependency 'Flutter'
  s.dependency 'Cosmos', '~> 23.0'
  s.platform = :ios, '9.0'

  # Flutter.framework does not contain a i386 slice.
  s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
  s.swift_version = '5.0'
end

Hi @andj207, Thanks for filing the issue. To investigate the issue further I would need a minimal and complete sample project.

[andj207]

Hi @maheshmnj here is the minimal and complete sample project. This is a flutter plugin project.

admobads_sample_plugin.zip

Edit: Please run the "admobads_sample_plugin/example/lib/main.dart" to see the error on iOS but work well on Android.

[maheshj01]

Thanks for the sample project @andj207, I am able to reproduce the same error, I don't really have much expertise on the native IOS, But from the error it looks like the google_mobile_ads sdk is not getting imported in the plugin, Hence the error.
Also as per this codelab the config looks correct.

@andj207 Have you found the solution? I have the same problem with you when I tried to create an Admob plugin for my apps. For me, I used google_mobile_ads: ^2.0.1 version.

[andj207]

@dtvtkien No, I'm still waiting for a fix. Currently I have to remove native ad type, just use other ads types or have to use google_mobile_ads in the main project code instead of in a plugin.

[lmmartinb]

@andj207 do you have any update or workaround? Thanks in advance

[DaeHyeonNam]

I solved it by using Runner.xcworkspace instead of Runner.xcodeproj file.
Hope it solves your problem too.

I solved it by using Runner.xcworkspace instead of Runner.xcodeproj file. Hope it solves your problem too.

I dont get it @DaeHyeonNam , what do you mean by "Using" Runner.xcworkspace instead of Runner.xcodeproj file ?

[DaeHyeonNam]

@Blast06 Have you tried to build the application using Runner.xcworkpsace? My error came up only when I tried to build using Runner.xcodeproj.
