How can I debug a Flutter Web App on Safari using the inspector?

I am using flutter to write a simple app, everything works fine on Android, iOS, and Chrome. (I've also tested on Firefox & Brave Browser, all's well).

However, on Safari (Mac & iOS), the flutter app gets stuck on the index.html file and does not load the PWA.

The error from the console on Safari Inspect

How can I know what the anonymous function in js_helper is, or what main.dart.js:57063 refers to?

Is there any way of building for web without minifying?
Has anybody encountered a scenario where everything works on all platforms except Safari?

Solution

You won't be able to debug it directly on Safari, but if you just want to test your app in safari with localHost, you can use these steps :

Enable 'developer' menu in Safari from settings of Safari :

Then check on 'Disable Cross-Origin restrictions"

Now after running release version of web app in chrome, use same app's address in Safari, you will be able to test it. Ex. http://localhost:51155/

to run in release mode : flutter run -d chrome --release

Hope this helps!
