Need null safety

I have a problem using the bcrypt hash for authentication between Android and IOS platforms. The code I use works for IOS but does not work for Android. The hahs have a different standard of android for IOS, the library generates a hash with initials $ 2a for IOS and for android $ 2b. I found it very strange that the same code works for IOS and for Android not. interesting that in the case of the hash generated for android with the initials $ 2b I can authenticate the user with it if I change the initials of the hash to $ 2a. I can't understand why it generates different password patterns between the platforms but only one of the patterns works, maybe it's a configuration problem, so I'll leave the specifications in case someone is willing to help me and thank you in advance.

** Code snippet using Bcrypt: **

NOTE: the server uses this same configuration as Bcrypt.

example of hash generated for IOS: $2a$10$prQYpugK9/r8mqyagF93FehEOsxeFSSixNLfsPURagyXqN1FAJn9a

example of hash generated for Android: $2b$10$zZUCr6112k86MvYCU48/tOFO7cbvKP3yXREt9grHbCqq3sKWpGHFa

CocoaPods could not find compatible versions for pod "flutter_bcrypt":
In Podfile:
flutter_bcrypt (from .symlinks/plugins/flutter_bcrypt/ios)

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

The plugin flutter_bcrypt uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing
it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration .

Generating hash of password using 'hashPw' is taking much time on iOS, aprox. 19s.
On Android it's working fine.

final password = "my_s3cret_p@ssw0rd";

var salt10 = inputUser.cryptoSalt;
print("--- salt10 " + salt10);

var pwh10 = await FlutterBcrypt.hashPw(password: password, salt: salt10);
print("--- pwh10 " + pwh10);
