Color Brightness Calculator API - Dart/Flutter Client

Color Brightness Calculator checks hex color brightness to classify values as light, dark, or medium, returning RGB components. Paid plans add WCAG contrast ratios, luminance scores, and recommended text colors.

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

Installation

Add this to your pubspec.yaml:

dependencies:
  apiverve_colorbrightness: ^1.2.3

Then run:

dart pub get
# or for Flutter
flutter pub get

Usage

      'hex': 'FF5733'
    });

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