How to Change the Gradient Color of a Polygon Using google-maps-react

If you’re using the google-maps-react library in your TypeScript project and want to change the gradient color of a polygon, you’re in the right place. In this article, we’ll explore two different solutions to achieve this.

Solution 1: Using the google-maps-react API

The google-maps-react library provides an API that allows you to customize the appearance of polygons, including their gradient color. Here’s an example code snippet:

import React from 'react';
import { Map, Polygon } from 'google-maps-react';

const gradient = [
  'rgba(255, 0, 0, 0.8)',
  'rgba(255, 255, 0, 0.8)',
  'rgba(0, 255, 0, 0.8)',
  'rgba(0, 255, 255, 0.8)',
  'rgba(0, 0, 255, 0.8)'
];

const MapComponent = () => {
  const polygonPaths = [
    { lat: 37.7749, lng: -122.4194 },
    { lat: 37.7749, lng: -122.3894 },
    { lat: 37.7549, lng: -122.3894 }
  ];

  return (
    
  );
};

export default MapComponent;

In the above code, we define a gradient array containing the colors we want to use for the polygon. Then, we pass this gradient array to the fillColor prop of the Polygon component. The fillOpacity prop controls the transparency of the color.

Solution 2: Using the Google Maps JavaScript API

If you prefer using the Google Maps JavaScript API directly, you can achieve the same result. Here’s an example code snippet:

import React, { useEffect } from 'react';

const MapComponent = () => {
  useEffect(() => {
    const map = new window.google.maps.Map(document.getElementById('map'), {
      center: { lat: 37.7749, lng: -122.4194 },
      zoom: 14
    });

    const polygonPaths = [
      { lat: 37.7749, lng: -122.4194 },
      { lat: 37.7749, lng: -122.3894 },
      { lat: 37.7549, lng: -122.3894 }
    ];

    const polygon = new window.google.maps.Polygon({
      paths: polygonPaths,
      strokeColor: '#000000',
      strokeOpacity: 0.8,
      strokeWeight: 2,
      fillColor: 'rgba(255, 0, 0, 0.8)',
      fillOpacity: 0.8
    });

    polygon.setMap(map);
  }, []);

  return 
;
};

export default MapComponent;

In this solution, we create a new instance of the google.maps.Polygon class and set its properties, including the fillColor and fillOpacity. We then add the polygon to the map using the setMap method.

Both solutions will result in a polygon with a gradient color on the Google Map.

That’s it! You now know how to change the gradient color of a polygon using the google-maps-react library in TypeScript. Feel free to choose the solution that best fits your project’s requirements.
