Storage needs dart:html File support for Flutter Web

[Aurangseb]

As you might know, uploading to Firestore is simple... if you have direct file access.

firebase_storage.FirebaseStorage.instance
        .ref('uploads/file-to-upload.png')
        .putFile(file);

The Web-Platform does not allow the regular File object for reading, but uses Dart:HTML File instead because of security reasons.

Now here is the problem:

putFile is missing dart:html File support

While the JS Web SDK for Firebase Storage supports uploading from JS File objects, the FlutterFire-Version does not support uploading the equivalent dart:html file type.

There is no method that accepts a dart:html file object for putFile.

Uploading via memory is not an option

Therefore the only way right now is to load the file into memory before uploading it to Storage. Which is obviously not a good idea for large files.

Conclusion

We really need putHtmlFile or something similar.
