BUG: Cannot handle escaped `-` in capturing groups when unicode flag is enabled

[jeswr]

The following evaluation fails with the error invalid escape sequence in regular expression despite being a valid regular expression in JS as of ES6

flutterJs.evaluate("const x = /[\-a]/u;")

This problem occurs on Linux - Debian Buster

If indeed you are using QuickJS, then yes, it is an upstream issue and flutter_js can do nothing about it. Here is me trying to run your code with the official quickjs CLI:

So unfortunately I would consider closing this issue here, as nothing can be done. You could consider using JScore instead.
