How to use

First, import the package

import 'package:kakaomap_webview/kakaomap_webview.dart';

You can use this as Widget and full screen webview

1. When you want to use as Widget

    KakaoMapView(
    width: size.width,
    height: 400,
    kakaoMapKey: kakaoMapKey,
    lat: 33.450701,
    lng: 126.570667,
    showMapTypeControl: true,
    showZoomControl: true,
    markerImageURL: 'https://t1.daumcdn.net/localimg/localimages/07/mapapidoc/marker_red.png',
    onTapMarker: (message) {
      //event callback when the marker is tapped
    });

2. When you want to use full screen webview

    KakaoMapUtil util = KakaoMapUtil();
    // String url = await util.getResolvedLink(
    //     util.getKakaoMapURL(37.402056, 127.108212, name: 'Kakao 본사'));

    /// This is short form of the above comment
    String url =
        await util.getMapScreenURL(37.402056, 127.108212, name: 'Kakao 본사');

    Navigator.push(
        context, MaterialPageRoute(builder: (_) => KakaoMapScreen(url: url)));

• Sample code

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

const String kakaoMapKey = 'yourKey';

class KakaoMapTest extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    Size size = MediaQuery.of(context).size;
    return Scaffold(
      appBar: AppBar(title: Text('Kakao map webview test')),
      body: Column(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: [
          KakaoMapView(
              width: size.width,
              height: 400,
              kakaoMapKey: kakaoMapKey,
              lat: 33.450701,
              lng: 126.570667,
              showMapTypeControl: true,
              showZoomControl: true,
              markerImageURL:
                  'https://t1.daumcdn.net/localimg/localimages/07/mapapidoc/marker_red.png',
              onTapMarker: (message) async {
                ScaffoldMessenger.of(context)
                    .showSnackBar(SnackBar(content: Text('Marker is clicked')));

                //await _openKakaoMapScreen(context);
              }),
          ElevatedButton(
              child: Text('Kakao map screen'),
              onPressed: () async {
                await _openKakaoMapScreen(context);
              })
        ],
      ),
    );
  }

  Future<void> _openKakaoMapScreen(BuildContext context) async {
    KakaoMapUtil util = KakaoMapUtil();

    // String url = await util.getResolvedLink(
    //     util.getKakaoMapURL(37.402056, 127.108212, name: 'Kakao 본사'));

    /// This is short form of the above comment
    String url =
        await util.getMapScreenURL(37.402056, 127.108212, name: 'Kakao 본사');

    Navigator.push(
        context, MaterialPageRoute(builder: (_) => KakaoMapScreen(url: url)));
  }
}

• Add polygon

polygonColor, polygonColorOpacity, strokeColor, strokeWeight, strokeColorOpacity

These features are optional. It can be null.

So you can add only polygon.

        KakaoMapView(
              width: size.width,
              height: 400,
              kakaoMapKey: kakaoMapKey,
              lat: 33.450701,
              lng: 126.570667,
              showMapTypeControl: true,
              showZoomControl: true,
              draggableMarker: true,
              mapType: MapType.BICYCLE,
              polygon: KakaoPolygon(
                polygon: [
                  KakaoLatLng(33.45086654081833, 126.56906858718982),
                  KakaoLatLng(33.45010890948828, 126.56898629127468),
                  KakaoLatLng(33.44979857909499, 126.57049357211622),
                  KakaoLatLng(33.450137483918496, 126.57202991943016),
                  KakaoLatLng(33.450706188506054, 126.57223147947938),
                  KakaoLatLng(33.45164068091554, 126.5713126693152)
                ],
                polygonColor: Colors.red,
                polygonColorOpacity: 0.3,
                strokeColor: Colors.deepOrange,
                strokeWeight: 2.5,
                strokeColorOpacity: 0.9
              ),
              markerImageURL:
                  'https://t1.daumcdn.net/localimg/localimages/07/mapapidoc/marker_red.png',
              onTapMarker: (message) {
                ScaffoldMessenger.of(context)
                    .showSnackBar(SnackBar(content: Text(message.message)));
        })

• Multiple markers

You can make multiple markers only in customScript now.

Still, there is a sample code.

    KakaoMapView(
        width: size.width,
        height: 400,
        kakaoMapKey: kakaoMapKey,
        lat: 33.450701,
        lng: 126.570667,
        customScript: '''
    var markers = [];

    function addMarker(position) {

      var marker = new kakao.maps.Marker({position: position});

      marker.setMap(map);

      markers.push(marker);
    }

    for(var i = 0 ; i < 3 ; i++){
      addMarker(new kakao.maps.LatLng(33.450701 + 0.0003 * i, 126.570667 + 0.0003 * i));

      kakao.maps.event.addListener(markers[i], 'click', function(){
        onTapMarker.postMessage('marker ' + i + ' is tapped');
     });
    }

		  var zoomControl = new kakao.maps.ZoomControl();
      map.addControl(zoomControl, kakao.maps.ControlPosition.RIGHT);

      var mapTypeControl = new kakao.maps.MapTypeControl();
      map.addControl(mapTypeControl, kakao.maps.ControlPosition.TOPRIGHT);

              ''',
        onTapMarker: (message) {
          ScaffoldMessenger.of(context)
              .showSnackBar(SnackBar(content: Text(message.message)));
    });
