Hello, how do I find out if a method call stands for an extension for nullable type. If i have the method

Type?.extForNullable()

I want to identify in a rule if this method is called, and not a version of it exclusive for a non-null instance of

Type

, or a more specialized version of it, like

SpecificType?.extForNullable()

, even if

SpecificType : Type

. I’m trying to visit dot-qualified expressions, since if I go for a safe expression I’m not calling a nullable version any way, but idk how to follow from here

Seems like

ForbiddenMethodCall

could be a good starting point: https://github.com/detekt/detekt/blob/master/detekt-rules-style/src/main/kotlin/io/gitlab/arturbosch/detekt/rules/style/ForbiddenMethodCall.kt 🤔
