fixed the issue. Will look into that further This is a new PHP 7.1 feature called Nullable types. You probably are on PHP <7.1.
Your question states you cannot upgrade your PHP version (which you should as versions below 7.2 soon will be depricated). For now you could install an older version of the library. 1.5.1 instead of 2.0.0.

I wish this helpful for you Create a function that generates the 10 digit random key then passes it through a validator with a unique rule set. If the validator gives you an error re-run the same function to generate a new one
code :
public function randomId(){

     $id = str_random(10);

     $validator = \Validator::make(['id'=>$id],['id'=>'unique:table,col']);

     if($validator->fails()){
          return $this->randomId();
     }

     return $id;
}

it should still fix some issue A for loop may be appropriate for you in this case. If you don't have an object for the codes, you can do something like this:
code :
$total_wanted = 100;
for ( $i = 0; $i < $total_wanted; $i++ ) {
    DB::table('codes')->insert(['code' => uniqid("prefix")]);
}
$total_wanted = 100;
for ( $i = 0; $i < $total_wanted; $i++ ) {
    $code = new Code;
    $code->code = uniqid("prefix");
    $code->save();
}
