添加firebase_storage后CocoaPods依赖冲突问题求助

问题情况 #

我开发了一款用Firebase Auth做身份验证、Cloud Firestore存储数据的Flutter应用，添加firebase_storage依赖后触发了CocoaPods版本兼容错误：Podfile.lock里的Firebase/Firestore版本是10.3.0，但cloud_firestore 4.4.5要求依赖Firebase/Firestore 10.6.0。执行pod repo update后问题依然存在，相关配置和报错信息如下：

报错信息 #

[!] CocoaPods could not find compatible versions for pod "Firebase/Firestore":
  In snapshot (Podfile.lock):
    Firebase/Firestore (= 10.3.0)

  In Podfile:
    cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 4.4.5, which depends on
      Firebase/Firestore (= 10.6.0)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Firebase/Firestore` inside your development pod `cloud_firestore`.
   You should run `pod update Firebase/Firestore` to apply changes you've made.

解决步骤 #

• 统一Firebase插件版本，避免any模糊匹配
  把pubspec.yaml中所有Firebase相关依赖的any替换为兼容的具体版本，确保它们对应相同的iOS Firebase SDK版本。比如可以用以下版本组合（均兼容Firebase iOS SDK 10.6.0）：

  firebase_auth: ^4.4.2
  firebase_core: ^2.12.0
  cloud_firestore: ^4.4.5
  firebase_storage: ^11.2.6
  

• 清理本地依赖缓存和Pod文件

  1. 执行Flutter清理命令：flutter clean
  2. 进入ios目录，删除旧的Pod锁文件和Pods文件夹：

     cd ios
     rm Podfile.lock
     rm -rf Pods
     

  3. 回到项目根目录，重新拉取依赖：flutter pub get

• 强制更新Firebase Pod版本
  进入ios目录，执行以下命令让CocoaPods直接更新Firebase/Firestore到满足要求的版本：

  pod update Firebase/Firestore
  

• 检查Podfile（可选）
  打开ios/Podfile，确保没有硬编码的Firebase版本限制语句，如果有直接删除，让CocoaPods自动处理版本兼容。
