[Bug]: "Call to undefined function Maatwebsite\\Excel\\resolve()" about laravel-excel HOT 2 CLOSED

I don't really support Lumen with this package, only on best effort basis as I don't have automated tests for Lumen. I've updated the resolve helper to app, but I don't know if there's more things that don't work correctly with Lumen

from laravel-excel.

Hi, just found out that in 3.1.52 using function resolve() which is not (i think) available in laravel/lumen-framework 6

this error can be fixed somehow with import a new function resolve(), because in older laravel, function resolve() is not registered yet in helpers.php (laravel helper).
for now i registered it in my own helper and do composer dump-autoload, maybe it helps for other who experience it.
maybe the owner of this library can confirm it.

if (! function_exists('resolve')) {
    /**
     * Resolve a service from the container.
     *
     * @param  string  $name
     * @param  array  $parameters
     * @return mixed
     */
    function resolve($name, array $parameters = [])
    {
        return app($name, $parameters);
    }
}
