Adds comprehensive formula evaluation capabilities using d4rt interpreter:
- FormulaEvaluator class for executing mathematical formulas
- Variable injection mechanism for d4rt compatibility
- Single output variable constraint with validation
- Comprehensive test suite with 15 test cases
- Working examples demonstrating physics and financial calculations
- Proper error handling for missing variables and invalid formulas
This enables the execution of user-defined mathematical formulas
with type-safe input validation and d4rt-based computation.
- Add FormulaEvaluator class with d4rt integration
- Support single output variable formulas with variable injection
- Include comprehensive error handling and validation
- Add 15 test cases covering evaluation scenarios
- Create working example with Newton's law, quadratic discriminant, etc.
- Export evaluator in main library file
Implements formula evaluation by injecting variable declarations
into d4rt source code, enabling execution of mathematical formulas
with input parameters.
- Added formula data classes with strict JSON parsing
- Cleaned up repository by removing .dart-tool and .dartServer cache directories
- Updated .gitignore to prevent future commits of cache/build artifacts
- Remove cached .dart_tool and .dartServer files from history
- Add .dartServer to .gitignore (dart analysis cache)
- Keep .dart_tool ignore entry
This prevents committing local tool/cache artifacts.
- Add VariableSpec class with magnitude field validation
- Add Formula class supporting multiple input/output variables
- Support d4rt_code as string or object with code field
- Add comprehensive tests for parsing and serialization
- Fix broken test import in pruebas_d4rt_test.dart
Follows README.md format requirements exactly
- Replace generic sample app description with comprehensive project overview
- Add detailed feature descriptions for formula search, computation, and sharing
- Document unit management and d4rt interpreter integration
- Include rich formula documentation with markdown and images support
- Maintain existing project structure documentation
