How to use `apply` in Kotlin when property and function have the same variable name data class Foo( val aaa: String, val bbb: String ) fun bar(aaa: String) { Foo().apply { aaa = aaa // this line gives error bbb = "bbb" } } IDE gives an error Val cannot be reassigned which suggests it's trying to reassign the function level aaa. how can I correctly use apply here to assign value of function level variable aaa to Foo's property aaa?
