Hey
Should we use annotations(Like @NonNull or @Nullable) with function arguments in kotlin to specify if function arguments are NonNull(Asking because of Null type handling in Kotlin being different)
For Example
```
    fun callApi(@NonNull context: Context) : String{
        return "hello world!"
    }
```

`Context` is already not nullable,  so the annotation is superfluous

okkk, also i had doubt about kotlin way of handling it I mean following code :
```
    fun callApi( str: String) : String{
        return "hello world!"
    }
```

specify non null String  parameter
and following code  :
```
  fun callApi( str: String?) : String{
return "hello world!"
}
```
means a nullable string parameter.
does this makes annotations for function arguements useless?

It makes `@NonNull` or `@Nullable` obsolete in kotlin code, yes. These things are backed into the Typesystem. <https://kotlinlang.org/docs/reference/null-safety.html>

okkkk, that clears a lot, thanks for your help...:slightly_smiling_face:
