Address Search Field

Widget builders to create 'address search widgets' which helps to autocomplete an address using a reference. They can be used to get Directions beetwen two places with optional waypoints. These widgets are made to be showed by onTap in a TextField with the showDialog function. It uses Dio, Google Maps for Flutter, Flutter Riverpod plugins. (This last plugin is to use extended objects that can be usable with GoogleMap Widget).

Getting Started

To use this plugin, add address_search_field as a dependency in your pubspec.yaml file. For example:

dependencies:
  address_search_field: ^5.0.3

Permissions

Android

On Android you'll need to add the internet permission to your Android Manifest file (located under android/app/src/main). To do so add next lines as direct child of the manifest> tag:

<uses-permission android:name="android.permission.INTERNET"/>

Usage

Import the package:

import 'package:address_search_field/address_search_field.dart';

GeoMethods

GeoMethods(
  googleApiKey: String,
  language: String,
  countryCode: String?,
  countryCodes: List<String>?,
  country: String?,
  city: String?,
  mode: DirectionsMode?,
  units: DirectionsUnits?,
);

• This object makes calls to Google APIs using the parameters set. It can do requests to Google places, geocode and directions APIs Get API key.
• Language support list here.
• List of countries here. Example:

final geoMethods = GeoMethods(
  googleApiKey: 'GOOGLE_API_KEY',
  language: 'en',
  countryCode: 'us',
  countryCodes: ['us', 'es', 'co'],
  country: 'United States',
  city: 'New York',
);

// It will search in unite states, espain and colombia. It just can filter up to 5 countries.
geoMethods.autocompletePlace(query: 'place streets or reference');

geoMethods.geoLocatePlace(
    coords: Coords(0.10, 0.10,)
);

geoMethods.getPlaceGeometry(
    reference: 'place streets',
    placeId: 'ajFDN3662fNsa4hhs42FAjeb5n',
);

// It needs a specific region, it will search in unite states.
geoMethods.getDirections(
    origin: Address(coords: Coords(0.10, 0.10)), 
    destination: Address(coords: Coords(0.10, 0.10))
);

AddressSearchBuilder

This widget can search addresses and permits you to work with them using an Address object.

Example:

GeoMethods geoMethods;
TextEditingController controller;
Address destinationAddress;

TextField(
  controller: controller,
  onTap: () => showDialog(
    context,
    builder: (BuildContext context) => AddressSearchDialog(
      geoMethods: geoMethods,
      controller: controller,
      onDone: (Address address) => destinationAddress = address,
    )
  ),
);

AddressSearchDialog.custom provides you a widget builder with the parameters and methods to create your own AddressSearchDialog and work with the addresses information.

Example:

GeoMethods geoMethods;
TextEditingController controller;
Address destinationAddress;

TextField(
  controller: controller,
  onTap: () => showDialog(
    context,
    builder: (BuildContext context) {
      return AddressSearchDialog.custom(
        geoMethods: geoMethods,
        builder: (
          BuildContext context,
          AsyncSnapshot<List<Address>> snapshot,
          Future<void> Function() searchAddress,
          Future<Address> Function(Address address) getGeometry,
          void Function() dismiss,
        ) {
          return MyCustomWidget(
            snapshot: snapshot,
            searchAddress: searchAddress,
            getGeometry: getGeometry,
            dismiss: dismiss,
            controller: controller,
            address: destinationAddress,
          );
        }
      );
    }
  ),
);

AddressLocator

This widget is a simple way to get an address reference in a TextEditingController from coordinates when the AddressSearchDialog is not created into a RouteSearchBox.

Example:

Coords coords;
GeoMethods geoMethods;
TextEditingController controller;
Address initialAddress;

// using coordinates you can get an address reference to be predefined in the widget and save all the address data in a variable.
AddressLocator(
  coords: coords,
  geoMethods: geoMethods,
  controller: controller,
  child: TextField(
    controller: controller,
    onTap: () => showDialog(
      context: context,
      builder: (BuildContext context) => AddressSearchDialog(
        controller: controller,
        geoMethods: geoMethods,
        onDone: (Address address) => initialAddress = address;,
      ),
    ),
  ),
);

RouteSearchBox

This widget helps you to works using a provider from flutter_riverpod. It permits you to work with AddressSearchDialog to search an origin Address, destination Address and optionally waypoints in a List<Address>. This widget is used to get directions from the addresses gotten by an AddressSearchDialog. provider.findRoute() function permits to set an address as origin or destination from a coordinates parameter. A completed example of how to use this widget could be found here.

Example:

final routeProvider =
    ChangeNotifierProvider<RouteNotifier>((ref) => RouteNotifier());

GeoMethods geoMethods;
TextEditingController originCtrl;
TextEditingController destCtrl;
Coords initialCoords;

RouteSearchBox(
  provider: routeProvider,
  geoMethods: geoMethods,
  originController: originCtrl,
  destinationController: destCtrl,
  locationSetters: [
    LocationSetter(
      coords: initialCoords,
      addressId: AddressId.origin,
    ),
  ],
  child: Column(
    children: [
      TextField(
        controller: originCtrl,
        onTap: () => showDialog(
          context: context,
          builder:(context) => 
              AddressSearchDialog.withProvider(
            provider: routeProvider,
            addressId: AddressId.origin,
          ),
        ),
      ),
      TextField(
        controller: destCtrl,
        onTap: () => showDialog(
          context: context,
          builder:(context) => 
              AddressSearchDialog.withProvider(
            provider: routeProvider,
            addressId: AddressId.destination,
          ),
        ),
      ),
      Consumer(
        builder: (BuildContext context, WidgetRef ref, Widget? _) {
          return ElevatedButton(
            child: const Text('Search'),
            onPressed: () async {
              final route = await ref.read(routeProvider).findRoute();
            },
          );
        },
      ),
    ],
  )
);
