Consider including flutter.js.map in the build output folder

Since we include flutter.js in the output build directory, it might be worthwhile to also include flutter.js.map by default.

Same issue. Web app breaks on mobile browsers, even when adding flags flutter build web --release --source-maps the file flutter.js.map is not generated

Could be something else is breaking your web app but the only error is the .map file error
In my case something else was breaking the app.
You can try by setting a placeholder map file and see which errors you have after

I moved some variables to a .env file and did not adjust git actions to set them while deploying.
Try to set this in your app as placeholder and see which error show up in console once the .map file error will be gone. The error will probably not show the exact code since it's not a real .map file

flutter.js.map

{
    "version": 3,
    "file": "flutter.js",
    "sources": [],
    "names": [],
    "mappings": ""
  }

@BenBroide Sure, I'll try that. Thanks for your suggestion.
