Specify dependencies in the run() method

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

 1class DatabaseSeeder extends Seeder
 2{
 3    public function run()
 4    {
 5        $user = User::factory()->create();
 6 
 7        $this->callWith(EventSeeder::class, [
 8            'user' => $user
 9        ]);
10    }
11}

 1class EventSeeder extends Seeder
 2{
 3    public function run(User $user)
 4    {
 5        Event::factory()
 6            ->when($user, fn($f) => $f->for('user'))
 7            ->for(Program::factory())
 8            ->create();
 9    }
10}
