# log function Null safety

void log (

1. String message,
2. {DateTime? time,
3. int? sequenceNumber,
4. int level: 0,
5. String name: '',
6. Zone? zone,
7. Object? error,
8. StackTrace? stackTrace}

)

Emit a log event.

This function was designed to map closely to the logging information collected by `package:logging`.

- `message` is the log message
- `time` (optional) is the timestamp
- `sequenceNumber` (optional) is a monotonically increasing sequence number
- `level` (optional) is the severity level (a value between 0 and 2000); see the `package:logging` `Level` class for an overview of the possible values
- `name` (optional) is the name of the source of the log message
- `zone` (optional) the zone where the log was emitted
- `error` (optional) an error object associated with this log event
- `stackTrace` (optional) a stack trace associated with this log event

## Implementation

    external void log(
      String message, {
      DateTime? time,
      int? sequenceNumber,
      int level = 0,
      String name = '',
      Zone? zone,
      Object? error,
      StackTrace? stackTrace,
    });
