I try to upload image to Firebase local storage emulator from flutter desktop software. I'm using file_selector_windows plugin for file selection.

void _openImageFile() async {
  final typeGroup = XTypeGroup(
    label: 'images',
    extensions: ['jpg', 'png'],
  );
  final files = await FileSelectorPlatform.instance
      .openFiles(acceptedTypeGroups: [typeGroup]);
  final file = files[0];
  final fileName = file.name;
  final filePath = file.path;
  final responseFireStorage = await http.post(
    Uri.parse('http://localhost:9199/v0/b/default-bucket/o?name=sample.jpg'),
    headers: <String, String>{
      'Content-Type': 'image/jpeg',
    },
    body: filePath,
  );
  print(responseFireStorage.statusCode);
}

Error: 400 BadRequest

  • You are telling the server you will send an image/jpeg, yet you are just sending a string (the path of the file) ... You may need to add the file content to the post request ... Commented Jul 3, 2021 at 14:22

  • Well, this may be an issue with the emulator then, if it's behaving differently from the firebase server. I never used either of them, so I can't really help you there. My hint was just the obvious inconsistency in your original request. Commented Jul 5, 2021 at 8:23
