ios - 使用 firebase-auth 时在 ios 上构建应用程序会导致 flutter 问题

Question

我正在制作一个使用 firestore 和 firebase_auth 的应用程序，在使用 android 时效果很好，但是当我在 ios 上构建它时，它会导致一系列问题:

 error: incompatible block pointer types sending 'void (^)(FIRUser *__strong, NSError *__strong)' to
    parameter of type 'FIRAuthDataResultCallback _Nullable' (aka 'void (^)(FIRAuthDataResult * _Nullable __strong, NSError * _Nullable __strong)')
                                                 completion:^(FIRUser *user, NSError *error) {
                                                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                      completion:(nullable FIRAuthDataResultCallback)completion;

                      completion:(nullable FIRAuthDataResultCallback)completion;

                                                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                              completion:(nullable FIRAuthDataResultCallback)completion;

                              completion:^(NSError *_Nullable error) {

如果需要此信息，我正在使用 firebase_auth 0.6.6。

我想通了这个问题。由于某种原因，这种情况发生在我身上，因为我的项目中同时使用了 firestore 和 firebase_auth ，因此对于 Android，我使用了这两个插件的一个版本，但在处理 iOS 时我需要使用这些插件的不同版本。
