    Vietmap.geoCode(VietMapAutoCompleteParams(textSearch: 'Hà Nội'));
    Vietmap.reverse(LatLng(21.027763, 105.834160));
    Vietmap.place('Place ID');
    Vietmap.routing(VietMapRoutingParams(points: [
      LatLng(21.027763, 105.834160),
      LatLng(21.027763, 105.834160)
    /// This function is used to get the style url of Vietmap,
    /// which provide the style of the map for VietmapGL plugin.

Depend on it

Run this command:

With Flutter:

 $ flutter pub add vietmap_flutter_plugin

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

  vietmap_flutter_plugin: ^0.0.5

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:vietmap_flutter_plugin/vietmap_flutter_plugin.dart';


import 'package:flutter/material.dart';
import 'package:vietmap_flutter_plugin/vietmap_flutter_plugin.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        // TRY THIS: Try running your application with "flutter run". You'll see
        // the application has a blue toolbar. Then, without quitting the app,
        // try changing the seedColor in the colorScheme below to Colors.green
        // and then invoke "hot reload" (save your changes or press the "hot
        // reload" button in a Flutter-supported IDE, or press "r" if you used
        // the command line to start the app).
        // Notice that the counter didn't reset back to zero; the application
        // state is not lost during the reload. To reset the state, use hot
        // restart instead.
        // This works for code too, not just values: Most code changes can be
        // tested with just a hot reload.
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      home: const MyHomePage(title: 'Flutter Demo Home Page'),

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  State<MyHomePage> createState() => _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  Future<void> _incrementCounter() async {
    var res = await Vietmap.reverse(const LatLng(21.027763, 105.834160));
    Vietmap.autocomplete(VietMapAutoCompleteParams(textSearch: 'Hà Nội'));
    Vietmap.geoCode(VietMapAutoCompleteParams(textSearch: 'Hà Nội'));
    Vietmap.reverse(const LatLng(21.027763, 105.834160));
    Vietmap.place('Place ID');
    Vietmap.routing(VietMapRoutingParams(points: [
      const LatLng(21.027763, 105.834160),
      const LatLng(21.027763, 105.834160)

    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.

  void initState() {


  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // TRY THIS: Try changing the color here to a specific color (to
        // Colors.amber, perhaps?) and trigger a hot reload to see the AppBar
        // change color while the other colors stay the same.
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        // Here we take the value from the MyHomePage object that was created by
        // the App.build method, and use it to set our appbar title.
        title: Text(widget.title),
      body: Center(
        // Center is a layout widget. It takes a single child and positions it
        // in the middle of the parent.
        child: Column(
          // Column is also a layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
          // TRY THIS: Invoke "debug painting" (choose the "Toggle Debug Paint"
          // action in the IDE, or press "p" in the console), to see the
          // wireframe for each widget.
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
              style: Theme.of(context).textTheme.headlineMedium,
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
