Dialog class

A Material Design dialog.

This dialog widget does not have any opinion about the contents of the dialog. Rather than using this widget directly, consider using AlertDialog or SimpleDialog, which implement specific kinds of Material Design dialogs.

This sample shows the creation of Dialog and Dialog.fullscreen widgets.

flutter create --sample=material.Dialog.1 mysample
