logging

logging copied to clipboard

I was experimenting with ANSI colors in log to create a new logging package, using both print and dart:developer/log functions.

I found some inconsistences:

1. dart:developer.log doesn't work at all in web platform. Nothing is printed. (print works just fine). Console also doesn't work (meaning: running in a console using flutter run)

2. Consoles (including VSCode console) shows ANSI color for both print and log, but Android Studio only shows color for print.

Example code:

const greenForeground = "\u001b[32m";
const yellowBackground = "\u001b[43;1m";
const resetColor = "\u001b[0m";

print("${greenForeground}${yellowBackground}This is print with green foreground and yellow background.${resetColor}");
log("${greenForeground}${yellowBackground}This is dart:developer.log with green foreground and yellow background.${resetColor}");

VSCode output for MacOS (and maybe Android, iOS, Linux and Windows):

Same for Android Studio Electric Eel (#AI-221.6008.13.2211.9477386) (notice log doesn't work with ANSI codes)

Running on Chrome: This is VSCode:

This is Chrome console (missing the log entry and also the green color should be dark, not bright (considering ANSI 16 colors specification)):

Running on console (default MacOS Terminal app) (Notice here is the wrong yellow (should be brighter, and log is missing)): MacOS build:

Web build:

Considering print is limited (specially on Android), dart:developer should provide a better cross-platform log option that is reliable no matter the platform it is running =(
