[!] 因未指定平台，自动为`Runner`目标分配`iOS`平台及版本`12.0`。请在Podfile中为此目标指定平台。

已尝试操作：

• flutter clean
• 进入ios目录执行pod install

解决方案 #

1. 修复flutter_app_version_checker的podspec问题 #

• 升级插件版本：在pubspec.yaml中更新flutter_app_version_checker到最新版本，执行flutter pub get
• 清除插件缓存：

  rm -rf ~/.pub-cache/hosted/pub.dartlang.org/flutter_app_version_checker-*
  flutter pub get
  

• 若仍无效，替换为功能类似的插件（如package_info_plus）

2. 指定Podfile的iOS平台版本 #

打开ios目录下的Podfile，修改平台配置为适配iOS 18的版本（建议最低14.0）：

platform :ios, '14.0'

3. 清理并重新构建 #

执行以下命令完成全量清理与依赖安装：

flutter clean
rm -rf ios/Pods ios/Podfile.lock ios/.symlinks
flutter pub get
cd ios
pod install --repo-update

4. 处理Firebase警告（可选） #

若需解决firebase_app_id_file.json不存在的警告，重新运行：

flutterfire configure
