Gold Price API - Dart/Flutter Client

Gold Price fetches real-time spot gold prices per troy ounce, gram, and kilogram. Each response includes the update timestamp, 24-hour price change, and market direction, while paid plans add custom currencies, karat prices, 7- and 30-day changes, 30-day stats, and hourly and daily history.

This is the Dart/Flutter client for the Gold Price API.
