Navigation logging

Track Flutter route transitions with ComonNavigatorObserver and keep them in the same structured logging pipeline.

comon_logger_navigation_flutter provides ComonNavigatorObserver.

Setup

import 'package:flutter/material.dart';
import 'package:comon_logger_navigation_flutter/comon_logger_navigation_flutter.dart';

MaterialApp(
  navigatorObservers: [ComonNavigatorObserver()],
)

What it logs

The observer emits records for:

PUSH
POP
REPLACE
REMOVE

Each record uses:

LogLevel.CONFIG
LogLayer.widgets
LogType.navigation

Record payload

Navigation records carry structured extra data such as:

action
route
previousRoute

That makes them easy to filter in ComonLoggerScreen or future telemetry pipelines.

Custom logger name

ComonNavigatorObserver(loggerName: 'my_app.navigation')

Use a custom name when route events should live under your own logger namespace instead of the default comon.navigation.

File logging

Persist logs to rotating files with retention, text formatting, or JSON lines output.

Sharing and export

Add ShareLogsAction to ComonLoggerScreen and export logs as text or JSON.
