🐛 [FIREBASE_STORAGE] mime/contentType undefined after upploading files to firebase storage #12363

pureimpro · 2024-02-21T00:11:37Z

Bug report

Describe the bug
Undefined contentType after uploading a file to firebase storage (tested on Android)

The workaround is to manually set the contentType before upload, with SettableMetadata :

UploadTask uploadTask = firebaseStorageRef.putFile(
        fileToUpload,
        SettableMetadata(
          contentType: "image/jpeg", // <<< YOU HAVE TO SPECIFY THE MIME TYPE OF YOUR FILE
        ),
      );

If you upload your file directly via the firebase console, contentType IS correctly recognized.

/!\ If your file is an image and you have a thumbnail generator cloudFunction for your bucket, no thumbnail for your image will be generated, since contentType is undefined.

Dart SDK 3.3.0
Flutter SDK 3.19.0
Debug mode

Steps to reproduce

Pickup a file with FilePicker and then firebaseStorageReference.putFile(), without any SettableMetadata:

UploadTask uploadTask = firebaseStorageRef.putFile(
        fileToUpload,
        //SettableMetadata(            <<< COMMENT THIS LINE
        //  contentType: "image/jpeg", <<< COMMENT THIS LINE
        //),                           <<< COMMENT THIS LINE
      );

Expected behavior

contentType automatically set corresponding to the file extension

Thanks for the report @pureimpro
I tried with plugin example which uses the said contentType with which I was able to upload the file properly without any errors. I tried on Android.

flutterfire/packages/firebase_storage/firebase_storage/example/lib/main.dart

Line 104 in bd2a678

contentType: 'image/jpeg',

pureimpro · 2024-02-21T19:59:25Z

thank you @darshankawar for your time and effort.

you are right, the plugin example provided does the job (I have also tested on Android).
The uploaded file DO have a contentType in the firebase console, because in the dart code, the contentType attribute is provided manually to SettableMetadata, before uploading the file :

SettableMetadata(
       contentType: 'image/jpeg', <<< THIS LINE IS SET MANUALLY
      customMetadata: {'picked-file-path': file.path},
    );

However, if you DO NOT provide SettableMetadata, or if you provide SettableMetadata WITHOUT contentType attribute, the uploaded file WILL NOT have any contentType. I have tested with .jpg image files, with the example plugin.

The type of the file is not inferred from the file extension, neither defaults to application/octet-stream, as expected from the documentation : https://firebase.google.com/docs/storage/flutter/upload-files#add_file_metadata

Add File Metadata
You can also include metadata when you upload files. This metadata contains typical file metadata properties such as contentType (commonly referred to as MIME type). The putFile() method automatically infers the MIME type from the File extension, but you can override the auto-detected type by specifying contentType in the metadata. If you do not provide a contentType and Cloud Storage cannot infer a default from the file extension, Cloud Storage uses application/octet-stream
