Flutter Web Build Firebase Hosting with command line parameters

[sangaritta]

It would be great if you can pass parameters to the flutter build command because I would like to change the render of my app from CanvasKit to HTML

Hey @sangaritta, thanks for the feedback. Currently, since the Firebase CLI does not support passing build arguments, to workaround this you could try changing "source": "." to "public": "build/web" in your firebase.json file. This will tell the Firebase CLI to use the build in build/web.

Also, you can specify hosting.predeploy in your firebase.json to run flutter build web --web-renderer html. This will tell the Firebase CLI to build your app before deployments.

Your firebase.json file would look something like:

{
  "hosting": {
    "public": "build/web",
    "predeploy": "flutter build web --web-renderer html",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
  }
}
