Flutter Firebase authentication only work when you give test phone number - firebase

Question

My code is working but it authenticate only the test phone no, which is given in the Firebase authentication.
when I'm trying with other number is directly going to PhoneVerificationFailed() and this is the exception msg im getting from this method :-
Error Message
Phone number verification failed. code: firebaseAuth. Message: this app is not authorized to use Firebase Authentication. Please verify that the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed]
Please have a look,and share your thoughts,may be im doing some mistakes.
// Example code of how to verify phone number
void _verifyPhoneNumber() async {
setState(() {
_message = '';
});
final PhoneVerificationCompleted verificationCompleted =
(AuthCredential phoneAuthCredential) {
_auth.signInWithCredential(phoneAuthCredential);
setState(() {
_message = 'Received phone auth credential: $phoneAuthCredential';
});
};
final PhoneVerificationFailed verificationFailed =
(AuthException authException) {
setState(() {
_message =
'Phone number verification failed. Code: ${authException.code}. Message: ${authException.message}';
});
};
final PhoneCodeSent codeSent =
(String verificationId, [int forceResendingToken]) async {
widget._scaffold.showSnackBar(const SnackBar(
content: Text('Please check your phone for the verification code.'),
));
_verificationId = verificationId;
};
final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
(String verificationId) {
_verificationId = verificationId;
};
await _auth.verifyPhoneNumber(
phoneNumber: _phoneNumberController.text,
timeout: const Duration(seconds: 5),
verificationCompleted: verificationCompleted,
verificationFailed: verificationFailed,
codeSent: codeSent,
codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
}
// Example code of how to sign in with phone.
void _signInWithPhoneNumber() async {
final AuthCredential credential = PhoneAuthProvider.getCredential(
verificationId: _verificationId,
smsCode: _smsController.text,
);
final FirebaseUser user =
(await _auth.signInWithCredential(credential)).user;
final FirebaseUser currentUser = await _auth.currentUser();
assert(user.uid == currentUser.uid);
setState(() {
if (user != null) {
_message = 'Successfully signed in, uid: ' + user.uid;
} else {
_message = 'Sign in failed';
}
});
}

SHA-1 configuration is not completed at Firebase end,once SHA-1 Configuration is done it will start to run perfectly.
