LoggingManager class

A manager that manages the Logger instances (provided as logger).

By default, the loggingManager does not have a log printing or further processing mechanism. For that, you have to listen to logs from a logger. This manager provides a LoggingTree which can do further processing by listening to logs from a logger. A LoggingTree is responsible for doing something with logs. If none provided, nothing will happen.

The logger that is used from this manager is attached to a logging tree. You don't have to get the logger from this instance, you can just use the logger's name as every logger created with a name will return the same actual instance whenever it is called with the same string name.

Records recieved from this logger and its childrens are sent to the logging tree for further processing (or just printing, attached logging tree is responsible for processing).

Constructors

LoggingManager({Logger? logger, LoggingTree? tree})

Creates a new LoggingManager with the given LoggingTree listening, & then processing logs from the logger.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

hasTree → bool

no setter

logger → Logger

A logger that is used with the logging tree attached in this manager. Records recieved from this logger and its childrens are sent to the logging tree for further processing (or just printing, attached logging tree is responsible for processing).

final

runtimeType → Type

A representation of the runtime type of the object.

Methods

addLogRecord(LogRecord record) → void

dispose() → void

getLogger(String name) → Logger

listenErrorsInIsolate(Isolate context) → void

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onRecordError(Object? error, StackTrace? stackTrace, {String? reason, bool fatal = false}) → Future<void>

Sends a log to the current logger managed by this manager.

plantTree(LoggingTree tree) → void

Attach a logging mechanism.

removeTree() → void

De-attach a logging mechanism.

runZoneGuardedWithLogging(FutureCallback onRun, {void onError(Object, StackTrace)?, Map<Object?, Object?>? zoneValues, ZoneSpecification? zoneSpecification}) → Future<void>?

This can be used to catch errors in a zone. ometimes, errors are instead caught by Zones. A common case where relying on Flutter to catch errors would not be enough is when an exception happens inside the onPressed handler of a button.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
