我创建了一个带有“FacebookShare”依赖项的颤振插件。我的 pod 规格如下所示，

Pod::Spec.new do |s|
  s.name             = 'plugin name'
  s.version          = '0.0.2'
  s.summary          = 'A new Flutter plugin for share image and text in social media'
  s.description      = <<-DESC A new Flutter plugin for share image and text in social media
                       DESC
  s.homepage         = 'https://github.com/jayarajm/flutter_share_social_media.git'
  s.license          =  :file => '../LICENSE' 
  s.author           =  '...' => '...' 
  s.source           =  :path => '.' 
  s.source_files = 'Classes/**/*'
  s.public_header_files = 'Classes/**/*.h'
  s.dependency 'Flutter'
  s.dependency 'FacebookShare'

  s.ios.deployment_target = '8.0'
  s.static_framework = true
end

在示例项目中，插件引用本地路径。所以我没有收到安装 pod 或运行项目的任何问题。发布到“https://pub.dartlang.org/”后。

我尝试在项目中使用 dart 包，但在安装 pod 时遇到问题。我附上了下面的错误，

这个错误你解决了吗？ 【参考方案1】：

我遇到了类似的问题，输出相同 <PBXGroup UUID...，就我而言，当我运行 pod install --verbose 时，我意识到 pod install 期间出现特定错误
