It's basically the same as executing `flutter --version`. This is especially useful for tools like Crashlytics or Sentry (see for example https://github.com/getsentry/sentry-dart/issues/416). Usage example: ```dart FlutterVersion.version; // 3.16.5 FlutterVersion.channel; // stable FlutterVersion.gitUrl; // https://github.com/flutter/flutter.git FlutterVersion.frameworkRevision; // 78666c8dc5 FlutterVersion.engineRevision; // 3f3e560236 FlutterVersion.dartVersion; // 3.2.3 ``` This approach has prior art as seen in #134179.
