A modern programming language that makes developers happier.

kotlinlang

The library accept `Boolean` but I am using `Boolean?`

the library doesn’t know how to handle `null`, since it expects `true` and `false` only

<@U6ECJCVAL> lol. will it cause any error or inconsistency?

<@U1901QPGA> thanks. just wondering if there is other alternative solution other than remove the question mark.

why would there be a inconsistency. the error says  its expecting a boolean, but your giving it a nullable boolean

could you paste a small code sample perhaps

```
override fun read(`in`: JsonReader?): Response {
        `in`?.beginObject()
        while (`in`?.hasNext()) { &lt;&lt; Here is the error
            val token: JsonToken = `in`.peek()
        }
    }
```

<@U6ECJCVAL> what is the syntax meaning of ``` for the `in`?

<@U6ECJCVAL> That one is automatic generate by the generator when I hit ALT + Insert to generate the override method.

so it  uses the double ticks to specify that your using it to name a vairable

doesn’t matter. just change the name from in, to something more understandble

So it does not represent anything but to tell the compiler this is a variable name?

So the indicate as `in` to tell the compiler actually this is a variable, not a keyword.
