Firebase custom verification email

Question

I read some other posts about this topic but couldn't finally figure out how to accomplish this.

I want to send the email-verification email normally send from firebase itself from my own email-provider (like mailjet e. g.) The reason is that I want to customize the email text etc.

I also read about creating a custom email handler which I would do too. But this just handles the action that happens when the user clicks on the link in the email.

At the moment I call this from my flutter app after the users sign up:

user.sendEmailVerification();

this makes firebase send the standard verification email to the user. Instead of doing that I'd need to send the email myself. But like seen here I need to have this oobCode generated. to generate a correct link to handle. I just can't find an example on how to do that. What would be the right approach to send the email myself? Maybe I just did not find the right resource. Thanks a lot.

The answer mentioned above is absolutely correct , I am just adding to that how you can create action url in two ways for testing and then deployment way. 1> for custom email action handler you would have to create your own handlers (using HTML and js , react app , flutter anything you want) after doing that you can either test your handler by routing traffic to it (localhost) using ngrok(that will provide you with https url to route traffic on localhost, preferred method for testing) , or you can deploy it and directly use that url . now with that url go to firebase(your project) -> authentication -> templates -> use whatever handler you want( example reset password or email verification) -> edit and add custom action url to route traffic to your handler( hosted(deployed) or local(ngrok routing) .
