Helper for accessing features in android.app.Dialog in a backwards compatible fashion.

Summary

Public methods
open static View	`requireViewById(@NonNull dialog: Dialog, id: Int)` Finds the first descendant view with the given ID or throws an IllegalArgumentException if the ID is invalid (< 0), there is no matching view in the hierarchy, or the dialog has not yet been fully created (for example, via `android.app.Dialog#show()` or `android.app.Dialog#create()`).

Public methods

requireViewById

@NonNull open static fun requireViewById(
    @NonNull dialog: Dialog, 
    id: Int
): View

Finds the first descendant view with the given ID or throws an IllegalArgumentException if the ID is invalid (< 0), there is no matching view in the hierarchy, or the dialog has not yet been fully created (for example, via android.app.Dialog#show() or android.app.Dialog#create()).

Note: In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.

Parameters
`dialog`	Dialog: the Dialog to search the View in
`id`	Int: the ID to search for

Return
`View`	a view with given ID
