API

• DataResult.success(S data) - Creates a successful result
• DataResult.failure(F failure) - Creates a failed result
• isSuccess - Returns true if result represents success
• when({required success, required error}) - Pattern matching requiring both cases
• whenOrNull({success, failure}) - Optional pattern matching

Documentation

• Comprehensive README with multiple examples
• Full API reference documentation
• Real-world usage scenarios
• Comparison with traditional error handling
• Best practices guide

Examples

• Basic success/failure handling
• API call simulation
• Form validation
• Database operations
• File operations
• Pattern matching demonstrations

This is the first stable release of data_result. The package provides a robust, type-safe way to handle operations that can succeed or fail, inspired by Result types from functional programming languages.
