Only if you're going by the strict UML definition of composition, which doesn't really apply here, since the industry has moved on a bit since UML was king.
Either way, you can use DI to do composition in the strictest UML way, provided every single dependency is transient and creates a new instance every single time. Even then though, when most devs talk about composition, they aren't referring to the strict UML definition.
Yeah but I was talking about the opposite. I can clearly spot composition in many frontend framework such as react or flutter but e.g. spring DI is a different thing to me.
