✨ About

Flutter package for practical multi-criteria decision-making, providing algorithms such as AHP, SAW, and TOPSIS (coming soon) to help developers perform weighting, evaluation, and ranking of alternatives easily and accurately within their Flutter applications.

Development Status:

This package is currently under active development. We are committed to continuously enhancing the features and algorithms to support a broader range of decision-making methods. In upcoming versions, we plan to add several popular algorithms such as SAW, TOPSIS, and other methods to provide a richer selection of decision-making techniques.

Status	Algorithm	Available in version
✅	AHP (Analytic Hierarchy Process)	1.0.0
✅	SAW (Simple Additive Weighting)	1.1.0
🔜	TOPSIS (Technique for Order Preference by Similarity to Ideal Solution)	1.2.0 (planned)

Thank you for your valuable feedback and continued support.

📚 Usage Guide

You can use this package in two ways depending on your needs:

1. Using all algorithms together
   Initialize the FlutterDecisionMaking class to access all available algorithms (currently AHP and SAW).
   More algorithms such as SAW and TOPSIS are planned for upcoming versions.

late FlutterDecisionMaking _decisionMaking;
AhpResult? _ahpResult;
List<SawResult>? _sawResult;

@override
void initState() {
  super.initState();
  _decisionMaking = FlutterDecisionMaking();
}

// Usage example:
// for AHP
_ahpResult = await _decisionMaking.ahp.getAhpResult(...);

// for SAW
_sawResult = await _decisionMaking.saw.calculateSawResult(...);

This is the easiest way if you want to use multiple algorithms in your project.

2. Using a specific algorithm only

If you only need a single algorithm (e.g., AHP), you can import and initialize it directly:

late AHP _ahp;
AhpResult? _ahpResult;

@override
void initState() {
  super.initState();
  _ahp = AHP();
}

// Usage example:
_ahpResult = await _ahp.getAhpResult(...);

📖 Algorithm Docs

For details on how to use the algorithm, you can visit the following documentation.

Link	Description
AHP Doc	If you need a method that is able to determine weights accurately through pairwise comparisons, validate the consistency of assessments, and work well on subjective or multilevel criteria.
SAW Doc	If you need a simple, fast, easy to calculate, and easy to implement method for ranking alternatives based on criteria weights and values.

📈 Performance Profiling

Major method logs:

• Start and end timestamps.
• Execution duration (in milliseconds).

Useful for debugging and optimization during development.
