How to set a default value of 1 year from now for expire_at in Laravel migrations?

I am creating fields for a table in Laravel. I want to create a expire_at column using $table->timestamps() but set a default date of 1 year from now.

Currently, I am trying the following:

$table->timestamps('expire_at')->default('1 year from now');

But this doesn’t seem to work. How can I achieve this?

Any help would be appreciated.
