My android studio is not able to understand the file extension(.mp3). it gives (The asset does not exist or has empty data.) error even though files are present and path is correct . i rechecked the
pubpsec.yaml folder. it shows no error and i got Question mark (?) in front of my audio files and not able to click those files . they are not responding or opening. Here are pictures of them:

and error shows like:
.
How can I resolve this issue ??
From the error, it seems like the path has double
assets/path (assets/assets/audio/download1.mp3). Try to remove the unnecessaryassets/path from wherever you're accessing that audio file.
