## Parametrisierte Abhängigkeiten { #parameterized-dependencies }

Alle Abhängigkeiten, die wir bisher gesehen haben, waren festgelegte Funktionen oder Klassen.

Es kann jedoch Fälle geben, in denen Sie Parameter für eine Abhängigkeit festlegen möchten, ohne viele verschiedene Funktionen oder Klassen zu deklarieren.
