#7187 and #7184 graduated Buttons and TextFields theming extensions to ready, but didn't update the docs. Similarly, #7190, which has not yet been merged in, is not updating the docs to reflect the graduation of the Dialogs theming extension to ready. This PR updates docs for Dialogs and TextFields theming extensions to reflect them being marked ready. Once #7190 is merged in the Dialogs changes here will be accurate. I will address the out-of-date Buttons docs once #7206 is merged in.
Dialogs
Dialogs inform users about a task and can contain critical information, require decisions, or involve multiple tasks.
Overview
To display a modal using MaterialDialogs you set two properties on the view controller to be presented. Set modalPresentationStyle to UIModalPresentationCustom and set transitioningDelegate to and instance of MDCDialogTransitionController. Then you present the view controller from the root controller to display it as a modal dialog.
Presentation and transition controller
Presenting dialogs uses two classes: MDCDialogPresentationController and MDCDialogTransitionController. These allow the presentation of view controllers in a material specificed manner. MDCDialogPresentationController is a subclass of UIPresentationController that observes the presented view controller for preferred content size. MDCDialogTransitionController implements UIViewControllerAnimatedTransitioning and UIViewControllerTransitioningDelegate to vend the presentation controller during the transition.
Alert controller
MDCAlertController provides a simple interface for developers to present a modal dialog according to the Material spec.
