Specify dependencies in the run() method

You can specify dependencies in the run() method of your seeder.

class DatabaseSeeder extends Seeder
{
    public function run()
    {
        $user = User::factory()->create();
 
        $this->callWith(EventSeeder::class, [
            'user' => $user
        ]);
    }
}

class EventSeeder extends Seeder
{
    public function run(User $user)
    {
        Event::factory()
            ->when($user, fn($f) => $f->for('user'))
            ->for(Program::factory())
            ->create();
    }
}
