Dialogs

To create a Dialog class, you should inherit it from DialogFragment from the bootstrap package.

class YesNoDialogFragment: DialogFragment()
{
    // implementation
    // access data in arguments
}

Other logic stays the same.

ViewModel

If you are using a ViewModel, you should inherit YesNoDialogFragment from DialogFragmentViewModel and pass the ViewModel as a parameter.

class YesNoDialogFragment: DialogFragmentViewModel<YesNoViewModel>()
{
    // implementation
    // access viewModel
}
