iOS模拟器运行Flutter应用失败：libphonenumber_plugin Pod兼容问题

在iOS模拟器运行名为coincrux的Flutter项目时，Pod install执行失败，报错信息如下：

[!] CocoaPods could not find compatible versions for pod "libphonenumber_plugin":
  In Podfile:
    libphonenumber_plugin (from `.symlinks/plugins/libphonenumber_plugin/ios`)

Specs satisfying the `libphonenumber_plugin (from `.symlinks/plugins/libphonenumber_plugin/ios`)` dependency were found, but they required a higher minimum deployment target.

Failed to run Pod install.

解决步骤 #

报错核心原因：libphonenumber_plugin依赖要求更高的iOS最低部署版本，当前Podfile设置的iOS 11.0不满足要求，按以下步骤修复：

1. 升级iOS部署目标
   打开ios/Podfile，将platform :ios, '11.0'修改为platform :ios, '12.0'（或更高版本，比如13.0，可根据依赖兼容情况调整）

2. 清理缓存并重新安装依赖
   依次执行以下命令：

   flutter clean
   cd ios
   pod deintegrate
   pod install
   cd ..
   flutter pub get
   

3. （可选）降级依赖版本
   若不想升级iOS部署目标，可尝试降低intl_phone_number_input的版本（libphonenumber_plugin是它的间接依赖），但此方法可能引发其他兼容问题，优先推荐升级iOS部署目标。
