Added some optional arguments to the init macro.
Only one macro call can be active in a crate because of conflicting implementations.
- default:
flutter_logger::flutter_logger_init!(); - sepcify level
flutter_logger::flutter_logger_init!(LeveFilter::Trace); - sepcify name
flutter_logger::flutter_logger_init!(logger_init); - sepcify both
flutter_logger::flutter_logger_init!(info_logger, LevelFilter::Info);
