多个命令产生颤动 GoogleUtilities

Question

我正在尝试为应用商店构建。使用命令flutter build ipa 并得到以下错误。虽然构建工作（当我从 Android Studio 运行时）在调试模式下，但我可以收到推送通知。

warning: Multiple targets match implicit dependency for linker flags '-framework GoogleUtilities'. Consider adding an explicit dependency on the intended target to
resolve this ambiguity. (in target 'Runner' from project 'Runner')

我为推送通知中的推送图像添加了 ImageNotification 新目标通知服务扩展

这是我的 pod 文件：

# Uncomment this line to define a global platform for your project
platform :ios, '14.3'

# 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)
  end
end

target 'ImageNotification' do
  use_frameworks!
  pod 'Firebase/Messaging'
end

Answer 1

将 pod 'GoogleUtilities' 添加到 PodFile 中的 ImageNotification 目标和 Runner 目标。

target 'ImageNotification' do
  ...
  pod 'GoogleUtilities'
end

target 'Runner' do
  ...
  pod 'GoogleUtilities'
end

然后删除 PodFile.lock 然后运行flutter clean，然后flutter pub get，然后flutter build ios。 之后在 Xcode 中打开 ios 模块并构建存档。 它会起作用的。
