Color Similarity Calculator API - Dart/Flutter Client

Color Similarity Calculator measures color similarity between two hex values. It returns an overall similarity score, a categorical match rating, and RGB and HSL channel breakdowns, while paid plans add Delta E and color distance metrics.

This is the Dart/Flutter client for the Color Similarity Calculator API.

Installation

Add this to your pubspec.yaml:

dependencies:
  apiverve_colorsimilarity: ^1.2.3

Then run:

dart pub get
# or for Flutter
flutter pub get

Usage

import 'package:apiverve_colorsimilarity/apiverve_colorsimilarity.dart';

void main() async {
  final client = ColorsimilarityClient('YOUR_API_KEY');

  try {
    final response = await client.execute({
      'color1': 'FF5733',
      'color2': 'FF6B47'
    });

    print('Status: ${response.status}');
    print('Data: ${response.data}');
  } catch (e) {
    print('Error: $e');
  }
}
