Flutter works with existing\ncode, is used by developers and organizations around the world, and is free and\nopen source.\n\n## Documentation\n\n* [Install Flutter](https://docs.flutter.dev/get-started)\n* [Flutter documentation](https://docs.flutter.dev)\n* [Development wiki](./docs/README.md)\n* [Contributing to Flutter](https://github.com/flutter/flutter/blob/main/CONTRIBUTING.md)\n\nFor release and other announcements, join the\n[flutter-announce](https://groups.google.com/g/flutter-announce)\nmailing list. Our documentation also tracks [breaking\nchanges](https://docs.flutter.dev/release/breaking-changes) across releases.\n\n## Terms of service\n\nThe Flutter tool may occasionally download resources from Google servers. By\ndownloading or using the Flutter SDK, you agree to the Google Terms of Service:\nhttps://policies.google.com/terms\n\nFor example, when installed from GitHub (as opposed to from a prepackaged\narchive), the Flutter tool will download the Dart SDK from Google servers\nimmediately when first run, as it is used to execute the `flutter` tool itself.\nThis will also occur when Flutter is upgraded (e.g. by running the `flutter\nupgrade` command).\n\n## About Flutter\n\nWe think Flutter will help you create beautiful, fast apps, with a productive,\nextensible and open development model, whether you're targeting iOS or Android,\nweb, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of\nyour choice.
