IsolateFileLogHandler constructor

IsolateFileLogHandler(Directory logFileDirectory, { int maxFilesCount = 5, String logNamePrefix = '_log', int maxLogSizeInMb = 5, List<BDLevel> supportedLevels = const <BDLevel>[BDLevel.warning, BDLevel.success, BDLevel.error], })

Create a new instance of IsolateFileLogHandler.

logNamePrefix will be used as prefix for each log file created by the instance of this IsolateFileLogHandler.

It's recommended that the logNamePrefix be unique in the app.

maxLogSizeInMb will be used to be deleted old log files. If in the logFileDirectory there's files with prefix logNamePrefix and the count of files is greater than maxFilesCount, older files will be deleted.

logFileDirectory is the directory where log files will be stored.

We assume that the logFileDirectory provided exist in the file system.

supportedLevels will be used to discard BDLogRecord with BDLevel lower than supportedLevels.

Implementation

IsolateFileLogHandler(
  this.logFileDirectory, {
  this.maxFilesCount = 5,
  this.logNamePrefix = '_log',
  this.maxLogSizeInMb = 5,
  this.supportedLevels = const <BDLevel>[
    BDLevel.warning,
    BDLevel.success,
    BDLevel.error,
  ],
})  : assert(
        logNamePrefix.isNotEmpty,
        'logNamePrefix should not be empty',
      ),
      assert(
        maxLogSizeInMb > 0,
        'maxLogSizeInMb should not be lower than zero',
      ) {
  _workerSendPort = _startLogging();
}
