AsyncHandler class base

A Handler that directly processes logs synchronously on the main thread under web/browser runtimes where standard isolates are unsupported.

Platform Architecture & Web Safety

Under browser/JS runtimes where Dart isolates are unsupported, AsyncHandler acts as a transparent, synchronous fall-through to the base Handler pipeline execution, running directly on the main event loop.

Lifecycle Management

Calling dispose on this stub disposes of the underlying sink cleanly.

Constructors

AsyncHandler({required LogFormatter formatter, required LogSink sink, List<LogFilter> filters = const [], List<LogDecorator> decorators = const [], LogEngine engine = const StandardEngine(), Duration? timeout})

Creates an AsyncHandler that defaults to main-thread processing under web platforms.

const

Properties

decorators → List<LogDecorator>

A list of LogDecorators applied sequentially to the intermediate LogDocument.
