Logger class

Use instances of logger to send log messages to the LogPrinter.

Constructors

Logger({LogFilter? filter, LogPrinter? printer, LogOutput? output, Level? level})
Create a new instance of Logger.

Properties

hashCode → int
The hash code for this object.
no setterinherited
init → Future<void>
Future indicating if the initialization of the logger components (filter, printer and output) has been finished.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

close() → Future<void>
Closes the logger and releases all resources.
d(dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
Log a message at level Level.debug.
e(dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
Log a message at level Level.error.
f(dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
Log a message at level Level.fatal.
i(dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
Log a message at level Level.info.
isClosed() → bool
log(Level level, dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
Log a message with level.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
t(dynamic message, {DateTime? time, Object? error, StackTrace? stackTrace}) → void
