IllegalStateException: Views added to a FragmentContainerView must be associated with a Fragment.

[victorhvs-iabcd]

Describe the bug
I'm facing illegalStateException after the upgrade of my project to kotlin 1.4 and jetpack libs.

To Reproduce
My code:
MaterialTapTargetPrompt.Builder(this@HomeFragment).setTarget(R.id.lp_layout).setPrimaryText("Olá").show()

Smartphone (please complete the following information):

• Device: Pixel 4
• OS: API 29
• Library version 3.0.0
• Kotlin version 1.4

Additional context
Instead of using fragment, I'm using activity and this solves the problem..

I got this too, this seems to be because of the navigation api

in show()

the code that gets the parent is

final ViewGroup parent = mView.mPromptOptions.getResourceFinder().getPromptParentView();

which returns the FragmentContainerView used as a navigation host

when I replaced it with

final ViewGroup parent = (ViewGroup)mView.mPromptOptions.getTargetView().getParent();

(which ofc is only correct in my project, because I know that the target view is inside the fragment I wish to target)

it works correctly

I created a pull request that solves the problem (for me) so when/if it gets approved it should work for you too
