flutterw_build_aar: Unsupported operation: Cannot add to a fixed-length list

[vvvictor07]

I got an exception because it is impossible to add element to fixed length list:

flutterw/packages/flutterw_build_aar/bin/flutterw_build_aar.dart

Line 22 in dfe70bf

arguments.addAll(['--build-number', pubspec.version!.canonicalizedVersion]);

Quick fix from my side was to rename argument arguments -> originalArguments

List<String> arguments = []..addAll(originalArguments);

But i would like to believe there should be more elegant solution
