Usage

Import the package:

import 'package:address_search_field/address_search_field.dart';

• This widget is a search box to write a reference about a place and find an address.

AddressSearchBox(
  controller: TextEditingController(),
  country: String,
  city: String,
  hintText: String,
  noResultText: String,
  exceptions: <String>[],
  coordForRef: bool,
  onDone: (BuildContext dialogContext, AddressPoint point) {},
  onCleaned: () {},
);

Parameters	Type	Description
controller	Optional	The controller allows you to interact with the text in the field.
country	Required, Not Null	You have to set in which country to search.
city	Optional	You may set in which city to search.
hintText	Required, Not Null	Text suggestion according to your language in the search box.
noResultsText	Required, Not Null	Message according to your language when the search box doesn't find anything.
exceptions	Optional	Results you don't want to show.
coordForRef	Optional	It's false by default. With the value true, it will use what the user typed in the search box as a valid Address.
onDone	Optional	When the search stops, it gives you an AddressPoint object with confirmation if a place has been found, full address, and coordinates.
onCleaned	Optional	When the search box is closed with an empty text field, this function is executed.

• This widget is a TextField that displays a AddressSearchBox by tapping it. It has 3 more parameters to personalize the TextField.

AddressSearchField(
  controller: TextEditingController(),
  decoration: InputDecoration(),
  style: TextStyle(),
  barrierDismissible: bool,
  country: String,
  city: String,
  hintText: String,
  noResultsText: String,
  exceptions: <String>[],
  coordForRef: bool,
  onDone: (BuildContext dialogContext, AddressPoint point) {},
  onCleaned: () {},
);

Parameters	Type	Description
decoration	Optional	The decoration to show around the text field.
style	Optional	The style to use for the text being edited.
barrierDismissible	Optional	It's true by default. With the value false, it won't close the search box when you tap outside it.

• When the address search is complete, you can get an AddressPoint object that provides the following values:

onDone: (BuildContext dialogContext, AddressPoint point) {
  bool found = point.found;
  String address = point.address;
  String country = point.country;
  double latitude = point.latitude;
  double longitude = point.longitude;
  Navigator.of(dialogContext).pop(); // Use it JUST in a AddressSearchField widget to close the dialog.
}

There are three possible outcomes:

1. If no search has been performed then the object will have null values ​​in its address, latitude and longitude variables.
2. If a place has been found from the reference, all the variables will be initialized.
3. If the desired location has not been found and the reference entered by the user is selected, there will be no latitude and longitude values ​​and the address will be the user's reference since nothing was found.

NOTE: You can also find an address by it's coordinates using await AddressPoint.fromPoint(latitude, longitude). If the address is not found, it will return null.

() async {
  AddressPoint point = await AddressPoint.fromPoint(latitude, longitude);
  if (point != null) print(point.address);
}

• This plugin also has an async static function called initLocationService to verify and request location permissions. You can use optional callbacks when location service is not enabled or if permission is not granted.

() async => await initLocationService(
  noServiceEnabled: () {},
  noPermissionGranted: () {},
);
