Flutter Image Compress giving result as null - firebase

Question

Compressed is coming out as null
File compressed = await FlutterImageCompress.compressAndGetFile(
img.path,
img.path.split('/').last,
quality: 80,
);
ref = firebase_storage.FirebaseStorage.instance
.ref()
.child('postimages/${Path.basename(img.path)}');
await ref.putFile(compressed);
This is what the error I am getting
E/flutter (12851): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception:
NoSuchMethodError: The getter 'absolute' was called on null.
E/flutter (12851): Receiver: null

This will work perfectly fine
final imageUri = Uri.parse(img.path);
final String outputUri = imageUri.resolve('./output.webp').toString();
print(imageUri.toFilePath());
File compressed = await FlutterImageCompress.compressAndGetFile(
img.path, outputUri,
quality: 80, format: CompressFormat.webp);
print(img.path);
print(outputUri);
ref = firebase_storage.FirebaseStorage.instance
.ref()
.child('postimages/${Path.basename(img.path)}');
await ref.putFile(compressed);
_imageName.add(await ref.getDownloadURL());
}
