BufferedTransport class

A Transport decorator that buffers LogEvents and flushes them in batches to an inner Transport.

Flushing is triggered by either:

Call flush manually to drain the buffer on demand, and dispose when the transport is no longer needed to cancel the timer and flush remaining events.

Example:

final transport = BufferedTransport(
  HttpTransport('https://logs.example.com'),
  maxSize: 50,
  flushInterval: Duration(seconds: 30),
);

// Or via extension:
HttpTransport('https://logs.example.com')
  .withBuffer(maxSize: 50, flushInterval: Duration(seconds: 30));

Constructors

BufferedTransport(Transport inner, {int maxSize = 100, Duration? flushInterval, LogLevel level = LogLevel.trace, Map<String, dynamic> config = const {}})

Properties

config → Map<String, dynamic>
Arbitrary key/value options passed to the transport at construction time.
finalinherited
flushInterval → Duration?
How often to automatically flush the buffer. When null, only maxSize triggers automatic flushes.
final
hashCode → int
The hash code for this object.
no setterinherited
inner → Transport
The inner transport that receives events on flush.
final
level → LogLevel
Minimum severity level this transport will handle.
finalinherited
maxSize → int
Maximum number of events to buffer before an automatic flush.
final
pendingCount → int
Number of events currently in the buffer.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

dispose() → Future<void>
Cancels the periodic timer and flushes any remaining buffered events.
emitLog(LogEvent event) → Future<void>
Performs the actual delivery of event to the transport's destination.
override
flush() → Future<void>
Sends all buffered events to inner and clears the buffer.
log(LogEvent event) → Future<void>
Delivers event to the destination if event.level >= this.level.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited
withBuffer({int maxSize = 100, Duration? flushInterval}) → BufferedTransport

Available on Transport, provided by the BufferedTransportExtension extension

Wraps this transport in a BufferedTransport.

Operators

The equality operator.
