x_logger

x_logger is a configurable logging package for Flutter, published on pub.dev. It gives apps named loggers (one per subsystem), log levels, and pluggable printers for pretty, JSON or colored output — all configured once and reused across the app.

Every record flows through three independent, swappable stages — a filter (whether to log), a printer (how it looks) and an output (where it goes) — so a single call can fan out to the console, an async on-device file, an in-app stream and a ring buffer at once. The history can be exported as a string or handed to a native share sheet, and it runs on Android, iOS, macOS, Windows and Linux. I built it during Wacyi to give the apps real, user-shareable diagnostics.
