Then run:

dart pub get

📖 Usage #

Import the package:

import 'package:pretty_print/pretty_print.dart';

🎯 Grouped Extension API (v2.1.0+) #

The new grouped extension system organizes methods into logical categories for better discoverability and cleaner code:

📝 Logging Methods #

// Status logging with styled headers
"Operation completed successfully!".logging.successLog();
"Application started".logging.infoLog();
"This feature is deprecated".logging.warningLog();
"Failed to connect to database".logging.errorLog();
"Debugging user authentication".logging.debugLog();
"Critical system failure".logging.criticalLog();
"Entering function".logging.traceLog();
"Database query took 150ms".logging.performanceLog();

🎭 Text Styling Methods #

// Text styling and effects
"Bold text".styling.bold();
"Italic text".styling.italic();
"Underlined text".styling.underline();
"Strikethrough text".styling.lineThrough();
"Blinking text".styling.blink();
"Bold + Underlined".styling.boldUnderline();
"All effects combined".styling.allEffects();

🌈 Color Methods #

// Text colors
"Red text".colors.red();
"Green text".colors.green();
"Blue text".colors.blue();
"Yellow text".colors.yellow();

// Background colors
"Text on red background".colors.onRed();
"Text on green background".colors.onGreen();
"Text on blue background".colors.onBlue();

// Combined styling
"Bold red text".colors.boldRed();
"Bold green text".colors.boldGreen();

// Special effects
"Rainbow text!".colors.rainbow();

📋 Formatting Methods #

// Layout and formatting
"Title".formatting.header();
"Content".formatting.box();
"Double border content".formatting.doubleBox();

// Lists and bullets
"First item".formatting.bullet();
"Second item".formatting.bullet();
"Step 1".formatting.numbered(1);
"Step 2".formatting.numbered(2);

// Alignment
"Left aligned text".formatting.leftAlign(30);
"Right aligned text".formatting.rightAlign(30);
"Centered text".formatting.center(30);

// Text formatting
"Important quote".formatting.quote();
"console.log('Hello')".formatting.code();
"Indented text".formatting.indent(2);

// Separators
"".formatting.separator();

// Utility methods
"Message".formatting.withPrefix(">>> ");
"Alert".formatting.withSuffix(" <<<");

🐛 Debug Methods #

// Development and debugging
"Variable inspection".debug.debugPrint();
"Fix this later".debug.todo();
"This needs attention".debug.fixme();
"Important note".debug.note();
"API response data".debug.inspect();

// Performance monitoring
"Performance check".debug.benchmark();
"Memory usage".debug.memory();
"Network request status".debug.network();
"Database query result".debug.database();

// Variable inspection
"userName".debug.variable("john_doe");
"age".debug.variable(25);
"isActive".debug.variable(true);

// Development status
"User authentication passed".debug.assertion();
"Legacy method usage".debug.deprecated();
"Experimental feature active".debug.experimental();
"Security check passed".debug.security();
"Configuration loaded".debug.config();

🔧 Basic PrettyPrint.log Usage #

For direct control over styling, you can still use the traditional PrettyPrint.log method:

// Simple colored text
PrettyPrint.log("Hello World!", textColor: PrintColor.green);

// Text with background and styling
PrettyPrint.log(
  " SUCCESS ",
  textColor: PrintColor.white,
  backColor: PrintColor.green,
  textWeight: TextWeight.bold,
);

// Combined effects
PrettyPrint.log(
  "Important Notice",
  textColor: PrintColor.red,
  textWeight: TextWeight.bold,
  textUnderline: TextUnderLine.underline,
  textBlink: TextBlink.slowBlink,
);

🎯 Why Use Grouped Extensions? #

The new grouped extension system provides several benefits:

🔍 Better Discoverability: IDE autocomplete shows only relevant methods for each category
📋 Organized Code: Methods are logically grouped by functionality
🧹 Cleaner API: Reduces namespace pollution
🚀 Enhanced Productivity: Find the right method faster
📚 Better Documentation: Each group is clearly documented

Migration Example #

// Old API (still works)
"Success message".successLog();
"Bold text".bold();
"Red text".red();

// New API (recommended)
"Success message".logging.successLog();
"Bold text".styling.bold();
"Red text".colors.red();

🎨 Advanced Usage Examples #

Complex Formatting #

// Create professional-looking output
"System Status Report".formatting.header();
"".formatting.separator();

"CPU Usage: 45%".debug.benchmark();
"Memory: 256MB".debug.memory();
"Network: Connected".debug.network();
"Database: Online".debug.database();

"".formatting.separator();
"All systems operational".logging.successLog();

CLI Application Example #

// Application startup
"🚀 MyApp v1.0.0".formatting.header();

// Progress indicators
"[1/4] Initializing...".logging.infoLog();
"[2/4] Loading config...".logging.infoLog();
"[3/4] Connecting to database...".logging.infoLog();
"[4/4] Ready!".logging.successLog();

// User interactions
"Enter your name: ".colors.cyan();
// ... get user input
"Welcome, John!".logging.successLog();

// Error handling
if (error) {
  "Connection failed: ${error.message}".logging.errorLog();
  "Please check your network settings".logging.warningLog();
}

Development & Debugging #

// Variable inspection
"userName".debug.variable(currentUser.name);
"isAuthenticated".debug.variable(user.isAuth);
"requestCount".debug.variable(stats.requests);

// Performance monitoring
"Database query completed".debug.benchmark();
"Memory usage: ${getMemoryUsage()}MB".debug.memory();
"API response time: ${responseTime}ms".debug.network();

// Development notes
"TODO: Implement caching".debug.todo();
"FIXME: Handle edge case".debug.fixme();
"NOTE: This is a temporary solution".debug.note();

🚀 Common Use Cases #
