flutter 版本升级到 flutter 2 后，我的 flutter 应用程序构建失败

错误：我的酒吧得到结果

/Users/sulfy/Developer/flutter/bin/flutter --no-color pub get 在 myflutterapp 中运行“flutter pub get”...

Because firebase_auth >=1.0.1 depends on firebase_auth_web ^1.0.1 which depends on http_parser ^4.0.0, firebase_auth >=1.0.1 requires http_parser ^4.0.0.
And because dio 3.0.10 depends on http_parser >=0.0.1 <4.0.0 and no versions of dio match >3.0.10 <4.0.0, firebase_auth >=1.0.1 is incompatible with dio ^3.0.10.
So, because myflutterapp depends on both dio ^3.0.10 and firebase_auth ^1.0.1, version solving failed.
pub get failed (1; So, because myflutterapp depends on both dio ^3.0.10 and firebase_auth ^1.0.1, version solving failed.)
Process finished with exit code 1

请建议我修复，我应该删除 dio 吗？或者是否有解决方法来解决这个问题？

在我将 firebase_auth 更新到最新版本后出现上述错误，因为我的带有电话号码身份验证的登录表单显示错误如下

Undefined class 'AuthCredential'.  Try changing the name to the name of an existing class, or creating a class with the name 'AuthCredential'.

我的手机验证码如下

     FirebaseAuth _auth = FirebaseAuth.instance;
    _auth.verifyPhoneNumber(
              phoneNumber: phone,
              timeout: Duration(seconds: 60),
              verificationCompleted: (AuthCredential credential) async {
//error: Undefined class 'AuthCredential'.
             
                Navigator.of(context).pop();
    
                UserCredential result = await _auth
                    .signInWithCredential(credential)
//error: The method 'signInWithCredential' isn't defined for the type 'FirebaseAuth'.
                    .then((value) => null)
                    .catchError((e) {
                  // print('User Exist');
                });
    //error: Undefined class 'UserCredential'.
                User user = result.user;
//error: Undefined class 'User'.
    
                if (user != null) {
              //redirect user
                } else {
                  // print("Error");
                }
                
              },
              verificationFailed: (FirebaseAuthException exception) {
              },
              codeSent: (String verificationId, [int forceResendingToken]) { },
              codeAutoRetrievalTimeout: (String verificationId) {
              //
              });

如果您的 pubspec.yaml 中有指定版本的 http_parser，您可以尝试删除此行，然后运行 flutter pub get。

如果上面没有解决问题，可以试试这个： https://dart.dev/tools/pub/dependencies#dependency-overrides
