Safemap is a Flutter/Dart package designed to safely extract values from JSON maps with type checking. It prevents runtime errors by returning null when the expected value type does not match, ensuring robust handling of untrusted or inconsistent JSON data. Ideal for parsing API responses or configuration files where data integrity is critical. The package supports all major platforms and integrates seamlessly into existing Dart projects.
Use cases
- Parsing API responses
- Handling dynamic JSON data
- Validating JSON structure
- Loading configuration files
- Safe deserialization of nested objects
- Preventing runtime type errors
Key features
- Type-safe value extraction
- Returns null on type mismatch
- Supports nested JSON structures
- Minimal boilerplate
- Cross-platform compatibility
- Simple, intuitive API
Suitable for
- Developers working with JSON APIs
- Teams prioritizing error resilience
- Projects requiring safe data parsing
- Apps processing user-generated or external JSON
- Beginners learning JSON handling in Dart
- Applications needing consistent fallback behavior
Considerations
- Does not validate non-type issues (e.g., missing keys)
- Requires manual handling of nested logic
- No built-in validation beyond types
- Not suitable for complex schema validation
- Limited to basic type coercion
- Null safety awareness required
