Bug Report: BigInt vs int type mismatches with Dart 3.8

Bug Report: BigInt vs int type mismatches with Dart 3.8

Package: libsql_dart
Version: 0.8.0
Dart SDK: 3.8.1
Flutter: Stable (Linux, Chrome target)

When running a Flutter app that depends on libsql_dart, the build fails with type errors related to int vs BigInt. It seems that flutter_rust_bridge now maps PlatformInt64 to BigInt, but parts of the generated code in libsql_dart still expect int.

This leads to mismatched constructor signatures and invalid assignments.
