DialogStack class
Manages a stack of modal dialogs.
Wraps its child and renders the top-most dialog as a Modal overlay. Provides static methods to push, pop, replace, and clear dialogs from anywhere in the subtree.
The stack handles esc to pop the top dialog automatically.
// Wrap your app or section with DialogStack
DialogStack(child: MyApp())
// Open a dialog from anywhere below
DialogStack.of(context).push(MyDialog());
// Close the top dialog
DialogStack.of(context).pop();
