Nearby Places

    import 'package:here_maps_webservice/here_maps.dart';
    import 'package:location/location.dart' as l; 
    import 'package:flutter/services.dart';
    
    var currentLocation;
    var location = new l.Location();
    List<dynamic> _nearbyPlaces=[]; 

    try {
      currentLocation = await location.getLocation();
      }on PlatformException catch (error) {
      if (error.code == 'PERMISSION_DENIED') {
        print("Permission Dennied");
      }
    }
    
    HereMaps(apiKey: "your apiKey")
          .exploreNearbyPlaces( lat: currentLocation.latitude, lon: currentLocation.longitude,offset: 10)
          .then((response) {
              setState(() {
                  _nearbyPlaces.addAll(response['results']['items']);
              });
          });

Popular Places

    import 'package:here_maps_webservice/here_maps.dart';
    import 'package:location/location.dart' as l; 
    import 'package:flutter/services.dart';
    
    var currentLocation;
    var location = new l.Location();
    List<dynamic> _explorePopularPlace = []; 

    try {
      currentLocation = await location.getLocation();
      }on PlatformException catch (error) {
      if (error.code == 'PERMISSION_DENIED') {
        print("Permission Dennied");
      }
    }
    
    HereMaps(apiKey: "your apiKey")
          .explorePopularPlaces(
              lat: currentLocation.latitude,
              lon: currentLocation.longitude,
              offset: 10)
          .then((response) {
        setState(() {
          _explorePopularPlace.addAll(response['results']['items']);
        });
      });

Geocoding Autocomplete

     import 'package:here_maps_webservice/here_maps.dart';
     
     List<dynamic> _suggestion = [];
     
     HereMaps(apiKey: "your apiKey")
           .geoCodingAutoComplete(query: "YourQuery")
           .then((response) {
         setState(() {
           _suggestion.addAll(response['suggestions']);
         });
       });

Geocoding

    import 'package:here_maps_webservice/here_maps.dart';
    
    Map<String, dynamic> latLon = Map();
    
    HereMaps(apiKey: "your apiKey")
        .geoCode(searchText: _searchController.text)
        .then((response) {
      setState(() {
        latLon = response['Response']['View'][0]['Result'][0]['Location']
            ['DisplayPosition'];
      });
    });

Reverse Geocoding

    import 'package:here_maps_webservice/here_maps.dart';
    import 'package:location/location.dart' as l; 
    import 'package:flutter/services.dart';
    
    var currentLocation;
    var location = new l.Location();

    try {
      currentLocation = await location.getLocation();
      }on PlatformException catch (error) {
      if (error.code == 'PERMISSION_DENIED') {
        print("Permission Dennied");
      }
    }
    
    Map<String,dynamic> response = HereMaps(apiKey: "your apiKey")
      .reverseGeoCode(lat: currentLocation.latitude, lon: currentLocation.longitude)
