)

Tap to Open Example (All Platforms)

CustomTooltip(
  tooltipContent: const Text('Tap to open/close this tooltip'),
  enableTapToOpen: true, // Enable tap to open on all platforms
  child: const Icon(Icons.info),

Note: When enableTapToOpen is set to true, mouse hover functionality is automatically disabled.

• All platforms (with enableTapToOpen: true): Tooltips toggle on tap, mouse hover is disabled

Code Architecture

The package is built with a modular architecture for better maintainability and code organization:

lib/src/
├── models/
│   └── preferred_position.dart          # Enum for tooltip positioning
├── painters/
│   └── custom_tooltip_shape_painter.dart # Custom painter for tooltip shapes
├── widgets/
│   └── tooltip_positioner.dart         # Widget for tooltip positioning
├── exports.dart                        # Export file for easy importing
├── custom_tooltip.dart                 # Main CustomTooltip widget
└── README.md                          # Source code documentation

Benefits of Modular Structure

• Separation of Concerns: Each file has a single, well-defined responsibility
• Maintainability: Smaller, focused files are easier to understand and maintain
• Reusability: Components can be imported and used independently
• Testing: Each component can be tested in isolation
• Extensibility: Easy to add new features or modify existing ones
