Instead of utilizing strings for asset paths, you may leverage code generation with flutter gen to create compile-safe asset references.

# pubspec.yaml 
flutter:
 assets:
   - assets/images/logo.jpg
Widget build(BuildContext context) {
  return Assets.images.logo.image();
}

16. Google APIs

To access the APIs included in the Google API Client Libraries, use the auto-generated Dart libraries provided by the googleapis package. You may access hundreds of Google APIs, including the Admin SDK, Calendar, Dialogflow, Drive, and more, by installing this one package.
