Usage

Here is a basic example of how to integrate the Flutter Earth Globe into your Flutter app:

import 'package:flutter/material.dart';
import 'package:flutter_earth_globe/flutter_earth_globe.dart';
import 'package:flutter_earth_globe/flutter_earth_globe_controller.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  late FlutterEarthGlobeController _controller;

   @override
  initState() {
    _controller = FlutterEarthGlobeController(
        rotationSpeed: 0.05,
        isBackgroundFollowingSphereRotation: true,
        background: Image.asset('assets/2k_stars.jpg').image,
        surface: Image.asset('assets/2k_earth-day.jpg').image);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Earth Globe Example'),
        ),
        body: SafeArea(
        child: FlutterEarthGlobe(
              controller: _controller,
              radius: 120,
            )
        ),
      ),
    );
  }
}

Customization

Create a list of Points and add them to the globe

final FlutterEarthGlobeController _controller = FlutterEarthGlobeController();
List<Point> points = [
      Point(
          id: '1',
          coordinates: const GlobeCoordinates(51.5072, 0.1276),
          label: 'London',
          isLabelVisible: true,
          style: const PointStyle(color: Colors.red, size: 6)),
      Point(
          id: '2',
          isLabelVisible: true,
          coordinates: const GlobeCoordinates(40.7128, -74.0060),
          style: const PointStyle(color: Colors.green),
          onHover: () {},
          label: 'New York'),
      Point(
          id: '3',
          isLabelVisible: true,
          coordinates: const GlobeCoordinates(35.6895, 139.6917),
          style: const PointStyle(color: Colors.blue),
          onHover: () {
            print('Tokyo');
          },
          label: 'Tokyo'),
      Point(
          id: '4',
          isLabelVisible: true,
          onTap: () {
            Future.delayed(Duration.zero, () {
              showDialog(
                  context: context,
                  builder: (context) => const AlertDialog(
                        title: Text('Center'),
                        content: Text('This is the center of the globe'),
                      ));
            });
          },
          coordinates: const GlobeCoordinates(0, 0),
          style: const PointStyle(color: Colors.yellow),
          label: 'Center'),
    ];

    for (var point in points) {
      _controller.addPoint(point);
    }

Load a background image that follows the rotation of the sphere and a sphere surface texture image

final FlutterEarthGlobeController _controller = FlutterEarthGlobeController();
@override
initState(){
    _controller.onLoaded = () {
        _controller.loadBackground(Image.asset('assets/2k_stars.jpg').image,
            followsRotation: true);
        _controller.loadSurface(Image.asset('assets/2k_earth-day.jpg',).image,
        );
    };

    super.initState();
}

Change the style of the sphere

final FlutterEarthGlobeController _controller = FlutterEarthGlobeController();
_controller.changeSphereStyle(SphereStyle(
      shadowColor: Colors.orange.withOpacity(0.8),
      shadowBlurSigma: 20));
controller
