QUESTION
I am using the firebase_storage: ^8.0.6 package on flutter web. I want to upload image to firebase storage that I get using FilePicker package.
The problem is that the new package uses the putFile() method to upload files. But File from dart:io doesn't work on flutter web and it also doesn't accept the File object from dart:html.
I can upload image as Blob using the putBlob() method but then it doesn't upload it as image type but it's type is application/octet-stream. I don't want to upload the image file as a blob.
ANSWER
Answered 2021-May-22 at 23:40You can still use .putFile when you use the File.fromUri() constructor and get the Uri from the PlatformFile object using Uri.dataFromBytes and passing the bytes to it.
The code below contains changes that should remove the error:

I'm using the MRTK for a hololens app and I need to select a file that the user puts in their document folder. I am trying to access the FileOpenPicker and use the PickSingleFileAsync() function from a button press to get the file and then load that into my app.
The code inside this function is basically what I am doing:
...ANSWER
Answered 2021-May-23 at 22:49ALL THANKS TO THIS POST! I finally found a solution to my issue. The biggest call that wasn't mentioned in any docs I looked through was this UnityEngine.WSA.Application.InvokeOnUIThread()
I didn't run into this, nor did I find any documentation on this being a solution for MRTK+unity for hololens development. So for anyone out there looking for a solution to the issue I will quote that link above in case it's broken in the future.
QUESTION
Goal:
- In the browser, read a file from the users file system as base64 string
- These files are up to 1.5GB
Issue:
- The followig script works perfectly fine on Firefox. Regardless of the filesize.
- On Chrome, the script works fine for smaller files (I've tested files of ~ 5MB size)
- If you pick a bigger file (e.g. 400MB) the FileReader completes without an error or exception, but returns an empty string instead of the base64 string
Questions:
- Is this a chrome bug?
- Why is there neither an error nor an exception?
- How can I fix or work around this issue?
Important:
Please note, that chunking is not an option for me, since I need to send the full base64 string via 'POST' to an API that does not support chunks.
Code:
...ANSWER
Answered 2021-May-12 at 22:03Here is a partial solution that transform a blob in chunks into base64 blobs... concatenates everything into one json blob with a pre/suffix part of the json and the base64 chunks inbetween
Keeping it as a blob allows browser to optimize the memory allocation and offload it to the disk if needed.
you could try to change the chunkSize to something larger, browser likes to keep smaller blob chunks in memory (one bucket)

QUESTION
Overview:
I am using the file-picker library to allow the user to select one or multiple files from their device. The selected files will have the ability to be previewed before the selected files will be sent for storage using HTTP/Multipart.
Problem:
The file-picker library returns a List\ and I have access to either a Uint8List? OR a Stream>?
Setting readStream and withData to both True does not return both the Uint8List? AND Stream>? - This would be helpful in my opinion.
If I use the Uint8List? I am able to load the file using the Flutter Image.memory method but I am unable to use the Uint8List to use the http.MultiPartFile.fromBytes() because it only accepts a List.
Alternatively, if I use the Stream>? I am able to use http.MultipartFile() and pass in the Stream>? but then I am unsure of how to generate a preview of the file/image using a Stream>?
Things I have considered but not sure how to accomplish
1- Is there a way convert a Uint8List? to a List?
2- Is there an alternative method for sending files using Uint8List?
3- Is there a way to receive both the Uint8List? AND Stream>? from the file-picker result?
I have copied a few snippets below but if you need more information please let me know. Thank you for your help in advance :)

This part is incorrect. Uint8List implements the List interface and can be passed to any functions/constructors that want a List. Therefore, you can use the MultipartFile.fromBytes constructor. If you saw a typing error, it was likely because you didn't promote the nullable type to a non-nullable one.
