Assets

Sound effects, animation files and image assets are declared centrally in one Dart file so you don't have to search the codebase to find them.

Where they live

lib/src/utils/assets_utils.dart

Every asset the app loads at runtime — SFX, Rive animations, static illustrations — is referenced from constants declared here. Swap the constant, drop the new file into assets/, and the app picks it up.

Drop your .mp3 or .wav files into:

assets/sfx/

Then point the SFX constants in assets_utils.dart at your new filenames.

After adding files

Flutter needs to know about new asset paths. Confirm your file is covered by the assets: list in pubspec.yaml — the shipped pubspec.yaml already covers the assets/ root recursively, so simply dropping a file into a covered subfolder is enough. If you add a brand-new subfolder, add it to pubspec.yaml and run:

flutter pub get
