Flutter Debugging Custom Log: Colorful Logs for Effortless Debugging

Dive into a world of vibrant Flutter debugging with our Colorful Logging utility! 

No Third-Party Plugins Needed!

This blog introduces a simple yet potent tool that adds a burst of color to your console messages, making log levels pop. 

Bonus: Say goodbye to cluttered production logs, as this utility seamlessly excludes itself in production builds.

• Visual Clarity: Colored messages stand out, aiding in the quick identification of log levels.
• Debugging Efficiency: Swiftly locate and focus on the most critical messages.
• Customization: Tailor colors or add more log levels to align with your preferences.
• Production Exclusion: Log messages exclusively surface in debug mode, leaving production logs pristine.
