The merge_map package provides a simple and efficient way to combine multiple Dart Maps into a single map, similar to JavaScript's Object.assign. It extends the Map class with a merge method that allows merging one or more maps into the original, with later maps taking precedence in case of key conflicts. This utility is particularly useful for configuration merging, state updates, or combining data from different sources. The package is lightweight and designed for seamless integration into existing Dart projects.
Use cases
- Merging configuration settings
- Combining API response data
- Updating state objects
- Handling dynamic form inputs
- Building composite data structures
Key features
- Simple merge method extension
- Supports multiple map inputs

- Lightweight and minimal dependencies
- Works seamlessly with Dart's native Map type
Suitable for
- Developers working with dynamic data merging
- Projects requiring configuration composition
- State management scenarios
- Apps processing multiple data sources
Considerations
- Does not support deep merging
- Limited to shallow merge operations
- No built-in conflict resolution beyond last-write-wins
- Not suitable for nested map structures requiring recursive merging
