Laravel upgrade 5.4 giving abstract method error

[shruti-ranium]

Hello,

hpolthof/laravel-translations-db version used - 0.5.0
Laravel - 5.3

While upgrading laravel from 5.3 to 5.4, it is giving following error

PHP Fatal error: Class Hpolthof\Translation\DatabaseLoader contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Illuminate\Translation\LoaderInterface::namespaces) in /vendor/hpolthof/laravel-translations-db/src/DatabaseLoader.php on line 6

[Symfony\Component\Debug\Exception\FatalErrorException]
Class Hpolthof\Translation\DatabaseLoader contains 1 abstract method and mu
st therefore be declared abstract or implement the remaining methods (Illum
inate\Translation\LoaderInterface::namespaces)

May I know the fix for it? Also, need fix for laravel 5.5 upgrade.

Thanks.
