Flatter pusher在Android中工作，但在IOS中不工作

Question

我使用一个包pusher_client：^2.0.0在Flutter中，它可以在Android上正常工作，但是当在ios模拟器上运行我的项目时，我在控制台中收到错误。

当我运行flutter run时，我得到以下错误，由于内容长度，我删除了错误的一些重复部分。

但在我注释掉上述文件和＜code＞pusher_client：^2.0.0＜code＞中的＜code＞时。yaml然后运行＜code＞颤振运行

有人能帮忙吗拜托

首先，更新您的IOs/pod文件以包含以下行:

平台：ios，“13.0”

将以下代码添加到Podfile中的post_install命令：

target.build_configurations.each do |config|
         config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
     end

例如，我的post_install是这样的：

post_install|安装程序|installer.pods_project.targets.each|目标|flutter_additional_ios_build_settings（目标）target.build_configurations.each做|配置|config.build_settings.delete'IPHONEOS_DEPLOYMENT_TARGET'end end end

转到您的 pubspec.yaml。并将pusher_client依赖关系替换为我的分叉：

pusher_client： git： url：git://github.com/thijskuilman/pusher_client.git

转到项目根文件夹。运行扑动干净

尝试在iOS设备或模拟器上运行该应用程序
