A common platform interface for the wifi_info_flutter plugin.
This interface allows platform-specific implementations of the wifi_info_flutter plugin, as well as the plugin itself, to ensure they are supporting the same interface.
To implement a new platform-specific implementation of wifi_info_flutter, extend WifiInfoFlutterPlatform with an implementation that performs the platform-specific behavior, and when you register your plugin, set the default WifiInfoFlutterPlatform by calling WifiInfoFlutterPlatform.instance = MyPlatformWifiInfoFlutter().
Strongly prefer non-breaking changes (such as adding a method to the interface) over breaking changes for this package.
See https://flutter.dev/go/platform-interface-breaking-changes for a discussion on why a less-clean interface is preferable to a breaking change.
