Unable to flutter run -d all

[ilyakam]

Today is my first day with Flutter. I got the "Hello World" app to work on both the virtual iPhone Xs and Pixel 3 after running a basic flutter create advertising_id_demo.

I then followed the installation instructions for this package. After adding advertising_id: ^0.9.1 as a dependency to the project's pubspec.yaml file and running flutter pub get, the "Hello World" app fails to build with the following error / stack trace:

I've created a demo repo that you can clone to help with debugging:
https://github.com/ilyakam/advertising_id_demo

Here's some info about my setup:

• macOS version 10.14.5
• Xcode version 10.2.1
• Android Studio version 3.4
• Flutter version 1.7.8+hotfix.2
• Cocoapods version 1.7.4
• Simulator version 10.2.1 running iPhone Xs on iOS 12.2
• Emulator running Pixel 3 on Android 9.0 (API 28 x86)

Could you please help? It's possible that I'm doing something wrong, I just don't know what.

I was able to make some more progress with this today, by:

1. Changing the configuration in ./ios/Runner.xcodeproj/project.pbxproj as described in this comment
2. Creating a new ./ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings file via Xcode with the following contents (as described in this comment):

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
     <key>BuildSystemType</key>
     <string>Original</string>
   </dict>
   </plist>

However, here is the main error I'm seeing now:

Failed to build iOS app
Error output from Xcode build:
↳
    ** BUILD FAILED **


Xcode's output:
↳
    /Users/ilya/Programs/flutter/.pub-cache/hosted/pub.dartlang.org/advertising_id-0.9.

    #import <advertising_id/advertising_id-Swift.h>
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1 error generated.

I suspect that the problem is with this line:

advertising_id/ios/Classes/AdvertisingIdPlugin.m

Line 2 in 128cea7

#import <advertising_id/advertising_id-Swift.h>

I looked all over this project for advertising_id-Swift.h and couldn't find one.

I've also noticed a few other of things…

1. This plugin's .podspec file has not been updated from the original Flutter template
2. Your avatar is Tux inside of Bugdriod (meaning, Linux and Android specific)
3. When filtering all 200 of your repos by language, neither Swift nor Objective-C appear even once

…which unfortunately begs the question: did you have a chance to test this plugin on iOS? And if so, how did you set it up on your end?

I have the same problem, could you solve it? @ilyakam

[ilyakam]

No, I gave up on Flutter because I found the ecosystem lacking (e.g., this thread) and switched to React Native instead, where I was able to make ample progress.

Were you able to fix the issue, @operando?
