Inspectopedia 2025.2 Help

Function or property has platform type

Reports functions and properties that have a platform type.

To prevent unexpected errors, the type should be declared explicitly.

Example:

fun foo() = java.lang.String.valueOf(1)

The quick fix allows you to specify the return type:

fun foo(): String = java.lang.String.valueOf(1)
