For being able to display your images from Firebase Storage on a Flutter web page you have to configure your data for CORS.

1. Open the GCP console, select your project and start a cloud terminal session by clicking the >_ icon button in the top navbar.
2. Click the open editor button (pencil icon), then create the cors.json file.
3. Run gsutil cors set cors.json gs://your-bucket

The cors.json file should look like this:

[
  {
    "origin": ["*"],
    "method": ["GET"],
    "maxAgeSeconds": 3600
  }
]

I set the origin to * which means that every website can display your images. But you can also insert the domain of your website there to restrict the access.

I had this problem as well. It seems the latest beta version is creating an error. I downgraded using git checkout 1.25.0-8.3.pre in my flutter folder.
