Error on web (Dart 3.0.0 & Flutter 3.10.2)

[Problem Analysis]
I have encountered this problem as well when running the project in a web environment. After inspecting the source code, I found the following issues:

The library “ai_barcode” is referencing another library called “ai_barcode_web”.
However, “ai_barcode_web” hasn’t been updated for a while and is incompatible with the method calls of the “qr” library it depends on.
Eventually, I realized that “ai_barcode” doesn’t actually need to reference “ai_barcode_web”. Therefore, I forked the source code and removed the problematic “ai_barcode_web” library.

[Final Solution]
To resolve this, you can comment out the original “ai_barcode” in the dependency file “pubspec.yaml” and add my forked library instead.

  #ai_barcode: 3.2.4
  ai_barcode:
