Php 7.1 Return Type-hint failing in Laravel 5.7

fixed the issue. Will look into that further So, for any one interested, I've got the answer from a different forum:
Simply import the class first:
code :
use Illuminate\View\View;
/**
 * @return View
 */
public function index(): View
{
    $products = Product::all();

    return view('products.index', ['products' => $products]);
}

Definition of type-hint in laravel documentation?

wish help you to fix your issue If you create an object via the container, it will try to resolve its dependencies that are represented by your object's constructor arguments. However, container needs to know what type of the dependency is, that's why you need to type-hint the arguments, meaning you need to define the type of the arguments, e.g.:
code :
public function __construct(Hasher $hasher) {
  //some logic
}
public function __construct(HasherContract $hasher) {
  //some logic
}

will be helpful for those in need PHP 7.1 will introduce the iterable typehint which will do exactly that:
code :
function test(iterable $items) { /*...*/ }
/**
 * @param \Traversable|array $items
 */
function test($items) { /*...*/ }

will be helpful for those in need You should use typevars with an upper bound: do T = TypeVar('T', bound=BaseClass) instead of T = TypeVar('T', BaseClass).

How can I type-hint a function where the return type depends on the input type of an argument?

around this issue This is exactly what function overloads are for.
In short, you do the following:
code :
from typing import overload

# ...snip...

@overload
def map_type(value: int) -> MyEnum: ...

@overload
def map_type(value: str) -> MyCustomClass: ...

def map_type(value: Union[int, str]) -> Union[MyEnum, MyCustomClass]:
    if isinstance(value, int):
        return MyEnum(value)
    elif isinstance(value, str):
        return MyCustomClass(value)
    raise TypeError('Invalid input type')

How should I type hint UserModel in a Laravel package?

hope this fix your issue I want to type hint the User model in a package. By default, it's App\User. In a channel class, this would be ok: , use the Contract that laravel uses for it's Auth Classes.
code :
public function join(Illuminate\Contracts\Auth\Authenticatable $user)
{
    //
}
