Hello Map

_|

This example demonstrates how to create a Flutter app that displays an interactive map using Maps SDK for Flutter.

How it works

The example app demonstrates the following feature:

• Display a map.

GemMap widget

Map Display and Cleanup

The following code outlines the main page widget, which displays the map and handles resource clean-up:

main.dart

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  void dispose() {
    GemKit.release();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.deepPurple[900],
        title: const Text('Hello Map', style: TextStyle(color: Colors.white)),
      ),
      body: const GemMap(
        key: ValueKey("GemMap"),
        appAuthorization: projectApiToken,
      ),
    );
  }
}

Explanation of key components

• The MyHomePage widget contains the scaffold that houses the map.
• The dispose method ensures that resources are released when the widget is destroyed.
• The GemMap widget is used to display the interactive map in the body of the scaffold.
