This issue was resolved in Laravel 8.5 https://github.com/laravel/framework/issues/34391​
Views can use something called Hints to tell the framework where to look for the view file. The theme always uses a hint of Mail::
which corresponds to the resources/views/vendor/mail/html
folder. What if we want to locate our theme somewhere else?
We can define our own hint and bind it into the system in the AppServiceProvider
with;
app/Providers/AppServiceProvider.phppublic function boot(){$this->loadViewsFrom(resource_path('views/mail'), 'appmail');}​
With this, we are saying that any view file that is hinted with appmail::
is found in the views/mail
folder.
Then, in the Notification, add the hint in the theme function;
public function toMail($notifiable){return (new MailMessage)->theme('appmail::mycorp')->subject('Password Reset')->line('Your password reset code is specified below')// etc
