Using Dart to Download a PNG File (Binary File) and displaying it not working

Question

I have a rest API which I am calling to retrieve a PNG image to display on my page.

My Code:

void getProfile         


        

Answer 1

The problem is this line:

Blob blob = new Blob(request.response);

The Blob constructor expects a List instead of another Blob (which request.response is in your use case): factory Blob(List blobParts, [String type, String endings])

Just delete the line, and directly call reader.readAsDataUrl(request.response), and it should work.
