Firebase Auth sendPasswordReset issue

[rlee1990]

Firebase Auth sendPasswordReset does not handle errors correctly when the email address does not exist. I receive this error:

I think this is a general problem regarding error handling in firebase_auth.
As in #18312 and #20223 . So I believe it's a duplicate.

And if it is, there's a PR already for that. flutter/plugins#775 .

[rlee1990]

Its not @ffeu the issue is if an error has happened like no account exists it should give an error but its giving the above and sometimes crashing the app

[cyanglaz]

@rlee1990 Are you still experiencing the issue?

[rlee1990]

@cyanglaz i have not tried in awhile so I'm not sure.

[cyanglaz]

@rlee1990 Thank you for the quick response. I would close the issue now since it seems to be being fixed flutter/plugins#775. If you continue to experience the issue, please free feel to reopen or open another issue with details.
