[FIXED] launchFragment while testing showing error

Issue

Using this guide to test dialog https://developer.android.com/guide/fragments/test The bottom sample

with(launchFragment<MyDialogFragment>()) {
        onFragment { fragment -> // here error
            assertThat(fragment.dialog).isNotNull()
            assertThat(fragment.requireDialog().isShowing).isTrue()
            fragment.dismiss()
            fragment.parentFragmentManager.executePendingTransactions()
            assertThat(fragment.dialog).isNull()
        }
    }

But here it shows error

 onFragment { fragment -> // error below

Type mismatch. Required: FragmentScenario.FragmentAction Found: (???) → Unit Cannot infer a type for this parameter. Please specify it explicitly

Solution

Guys the solution was Kotlin version. So update Kotlin plugin in studio solves the issue
