implementation of the log crate for using rust together with flutter/dart and flutter_rust_bridge to get logs from rust into your app.

• panic: print rust panics to the log stream.

The library contains a macro for all the code you have to include in your flutter_rust_bridge api definition. Calling the macro without args creates the init function "setup_log_stream" with LeveFilter::Debug. You can also specify function name and LevelFilter (or only one). The macro can only be called once because of conflicting implementations

// only one of these calls can be active
flutter_logger::flutter_logger_init!(); // default
// flutter_logger::flutter_logger_init!(LeveFilter::Trace); // sepcify level
// flutter_logger::flutter_logger_init!(logger_init); // sepcify name
// flutter_logger::flutter_logger_init!(info_logger, LevelFilter::Info); // sepcify both

pub fn test(i: i32) {
    // using the 'log' crate macros
    info!("test called with: {i}")
}

Future setupLogger() async {
    setupLogStream().listen((msg){
    // This should use a logging framework in real applications
        print("${msg.logLevel} ${msg.lbl.padRight(8)}: ${msg.msg}");
    });
}

void main(){
    await RustLib.init();
    await setupLogger();
    await test(i: 5);
}

This works also on mobile apps like Android where println() in rust isn't shown in the console.
