+# in_app_review_platform_interface
+
+A common platform interface for the [`in_app_review`][1] plugin.
+
+This interface allows platform-specific implementations of the `in_app_review`
+plugin, as well as the plugin itself, to ensure they are supporting the
+same interface.
+
+# Usage
+
+To implement a new platform-specific implementation of `in_app_review`, extend
+[`InAppReviewPlatform`][2] with an implementation that performs the
+platform-specific behavior, and when you register your plugin, set the default
+`InAppReviewPlatform` by calling
+`InAppReviewPlatform.instance = MyInAppReview()`.
+
+# Note on breaking changes
+
+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.
