flex_logger_file 1.0.4

File logging provider for FlexLogger - writes logs to local files with rotation support

1.0.4

• Updated dependencies (intl: ^0.20.2, flex_logger: ^1.0.4).

1.0.3

• Added optional dateFormat parameter to FileFormatter, SingleFileStrategy, and FileLoggerProvider.singleFile().
• Added providerId parameter to rotating() and timeBased() factory constructors.
• SingleFileStrategy cleanup uses streaming I/O for better memory efficiency.
• dispose() in all strategies now awaits in-progress operations before teardown.
• Improved error recovery in TimeBasedFileStrategy file switches.
• Re-exported DateFormat from barrel file.

1.0.1

• FileFormatter output is now pipe-separated with fixed-width level columns; error and critical entries are wrapped in ─ separator lines.
• SingleFileStrategy and RotatingFileStrategy now use utf8.encode for accurate byte-count tracking instead of String.length.
• Breaking: RotatingFileStrategy removed directoryPath and fileName constructor parameters — use filePath instead.
• Breaking: FileObserver removed logFilePath getter and watchLogFile() method — use the strategy's watchLogFile() directly.
• SingleFileStrategy removed the internal FileSystemEvent watcher; cleanup is now triggered only by write frequency.
• FileObserver callbacks (onLog, onException, onError) updated to Future<void> to match FlexObserver changes.
• TimeBasedFileStrategy uses path.join for file path construction.

1.0.0

• Initial release
• FileLoggerProvider implementing LoggerProvider: default constructor with custom FileStrategy; factory constructors singleFile, rotating, timeBased; optional formatter, filter, providerId.
• FileObserver (FlexObserver): writes logs via FileStrategy; initialize(), dispose().
• FileFormatter implementing LogFormatter: format [YYYY-MM-DD HH:MM:SS.mmm] [LEVEL] message; error and stack trace (stack trace abbreviated if > 1000 chars).
• FileStrategy (abstract): initialize(), write(String), dispose(), currentLogFilePath.
• SingleFileStrategy: single file; filePath?; optional maxFileSize, maxAge, cleanupCheckInterval; buffers during cleanup; timestamp-based line filtering for age/size; default path <documents>/app.log.
• RotatingFileStrategy: size-based rotation; filePath?; maxFileSize (default 10 MB), maxBackupCount (default 5); current file renamed to .1, .2, …; buffers during rotation; no logs lost; default path <documents>/app.log.
• TimeBasedFileStrategy: one file per day; directoryPath?, fileNamePattern ({prefix}, {date}), filePrefix; optional maxAge, maxFiles; buffers during file switch.
• Optional per-provider filter (e.g. MinLevelFilter); default AcceptAllFilter.
• Auto creation of log directories by all strategies.
