Context receiver doubt 🧵
Copy code
context(FieldSetInfo.Component, BeFormFieldComposer)
fun camera() : TrailingIcon {
    return TrailingIcon(
        type = TrailingIcon.Type.CAMERA,
        onClicked = {
            formNavigator.launchCamera(this)
        }
    )
}
If I do this I get 
this is not defined in this context
however calling 
formNavigator.launchCamera(copy())
for example, works
whats the right way of calling the 
FieldSetInfo.Component
context here?

it's gonna be 
this@Something
, although I'm not sure whether the something would be 
Component
or 
FieldSetInfo

Copy code
this@camera
is of the type I want as per the IDE autocomplete but I get the same error message

Alternatively, you can use this nice function:
Copy code
context(A) fun <A> given(): A = this@A
like this: 
given<FieldSetInfo.Component>()

IDE autocomplete is wrong in this case. Intellij doesn't support context receivers well just yet

ah good to know
So this@Component did it thanks! I do think your proposal for the "summoning" function sounds quite cool
