+# Flutter Packages Style Guide
+
+## Introduction
+
+This style guide outlines the coding conventions for contributions to the
+flutter/packages repository.
+
+## Style Guides
+
+Code should follow the relevant style guides, and use the correct
+auto-formatter, for each language, as described in
+[the repository contributing guide's Style section](https://github.com/flutter/packages/blob/main/CONTRIBUTING.md#style).
+
+## Best Practices
+
+- Code should follow the guidance and principles described in
+  [the flutter/packages contribution guide](https://github.com/flutter/flutter/blob/master/docs/ecosystem/contributing/README.md).
+- Code should be tested. Changes to plugin packages, which include code written
+  in C, C++, Java, Kotlin, Objective-C, or Swift, should have appropriate tests
+  as described in [the plugin test guidance](https://github.com/flutter/flutter/blob/master/docs/ecosystem/testing/Plugin-Tests.md).
+- PR descriptions should include the Pre-Review Checklist from
+  [the PR template](https://github.com/flutter/packages/blob/main/.github/PULL_REQUEST_TEMPLATE.md),
+  with all of the steps completed.
