Is this code is correct to get reset password in email using firebase??

Arjun, Hi!

Please, never post your code as print-screen. All real developers really hate this. And you don't want such adverse reaction, right? :)

As about your code. Hard to tell. Looks less or more good.

Try asking some more precise question - if you have something not working, describe the problem as best as possible. I'm afraid there is no chance to get response to "is this awkward 26-lines fragment correct despite I won't told you what is happening". :)

Good luck!
