flutter clean
deleted podfile.lock
deleted pods folder
pod deintegrate
pod repo update
pod install

but don't help me to solve this error

[coredeveloper]

Having the same issue.

[coredeveloper]

firebase_auth: 0.15.4 <- this helped to solve the issue for a while (while devs a busy digging).

[knaeckeKami]

Me too.
It seems firebase_core 0.4.4+2 is the culprit.
Forcing the old version:

  firebase_core: 0.4.4 # do NOT use ^ !

Fixed to the build for me.

[motorahul]

i didnot receive otp for web mobile authentication

[woody-kim]

I changed dependencies. try this.

dependencies: 
  firebase_auth: 0.15.3
dependency_overrides:
  firebase_core: 0.4.4

Don't use ^ in version.

[motorahul]

Nothing happened no OTP again

I'm having this issue related to Cloud Firestore. Can confirm using firebase_core: 0.4.4 "fixes" the issue. Thank you everyone for posting this so timely, y'all saved my butt!

Rolling back firebase_auth to 0.15.4 worked for me. I'm not exactly certain which version broke, but 0.15.4 works and 0.15.5+2 does not.

[athlona64]

i have some problem with OTP can't sent in some time

[divyanshub024]

Even after rolling back firebase_auth to 0.15.4 I'm getting this error

/Users/divyanshubhargava/workspace/flutter/.pub-cache/hosted/pub.dartlang.org/firebase_auth-0.15.5+2/darwin/Classes/FLTFirebaseAuthPlugin.m:7:9: fatal error: 'UserAgent.h' file not found
    #import "UserAgent.h"

[awhitford]

@divyanshub024 please remember to remove the ^ before the version -- because you don't want to accept the newer version; and you may need to flutter clean too before building.

[divyanshub024]

@awhitford Oh I missed that. It was taking newer because of ^. Thanks a lot for the help.
