Can not build with bitcode enabled

[ChrisLmis]

I need to compile the app with bitcode enabled. When bitcode is enabled, I get the following build error:

ld: -U and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together

This is a result of the setup requirements for this plugin where you have to add these linker flags:

-Wl,-U,_FlutterUnityPluginOnMessage

I understand that this is required to allow Unity to talk to Flutter. Is there any way around this problem?

@ChrisLmis I'm looking for another alternative to fixing this. It's top of my todo list

A temporary fix is to add these line to the end of 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['ENABLE_BITCODE'] = 'NO' 
    end 
  end
end

If you still have issue, try this full Podfile

# Uncomment this line to define a global platform for your project
platform :ios, '10.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

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['ENABLE_BITCODE'] = 'NO' 
    end 
  end
end

I've spend 6 hour today to get the project compiled, it's not fun...

This was fixed in v4.1.0, please use a matching unitypackage
