[ Widget Preview ] Add support for theme and brightness properties on Preview (#167001)
The `theme` parameter of `Preview(...)` allows for developers to provide
a callback that returns a `PreviewThemeData` instance which can contain
theming data for Material and Cupertino widgets in both light and dark
modes. The provided theme data will be injected into the widget tree and
applied to the previewed widget.

The `brightness` parameter allows for developers to specify an initial
brightness setting (e.g., light vs dark mode) for the previewed widget.
If not provided, the current system default is used.

A new button has also been added to each widget preview card that allows
for toggling between light and dark mode for individual previews.

Example of calling platform services from Flutter

This project demonstrates how to connect a Flutter app to platform-specific services on iOS using Swift. The equivalent version of this project in Objective C is found in examples/platform_channel.

You can read more about accessing platform and third-party services in Flutter.

iOS

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or you can open ios/Runner.xcworkspace in Xcode and build/run the project as usual.

Android

We refer to the platform_channel project.
