Map location picker component for flutter based on google maps flutter

google map location picker

Location picker using the official google_maps_flutter.

The Location-picker allows you to quickly render Google Maps with an overlaying marker, providing an easy and quick plug-and-play location picker. It also supports address/place autocomplete search powered by Google Places API.

Here is the map location picker component for Flutter based on google_maps_flutter. We will particularly mention getting started, how to use it, and some notes. 

Getting Started

Move to the getting started section. This special component flutters based on Google_maps_flutter will support both operating systems, IOS and Android. Detailed below: 

Get an API key at https://cloud.google.com/maps-platform/.

Android

Specify your API key in the application manifest android/app/src/main/AndroidManifest.xml:

<manifest ...
  <application ...
    <meta-data android:name="com.google.android.geo.API_KEY"
               android:value="YOUR KEY HERE"/>

iOS

Specify your API key in the application delegate ios/Runner/AppDelegate.m:

#include "AppDelegate.h"
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GMSServices provideAPIKey:@"YOUR KEY HERE"];
  [GeneratedPluginRegistrant registerWithRegistry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

Or in your swift code, specify your API key in the application delegate ios/Runner/AppDelegate.swift:

import UIKit
import Flutter
import GoogleMaps

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GMSServices.provideAPIKey("YOUR KEY HERE")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Opt-in to the embedded views preview by adding a boolean property to the app’s Info.plist file
with the key io.flutter.embedded_views_preview and the value YES.

Using

For message localization inside the library please add in MaterialApp

import 'package:google_map_location_picker/generated/i18n.dart' as location_picker;

MaterialApp(
  localizationsDelegates: const [
    location_picker.S.delegate,
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
    GlobalCupertinoLocalizations.delegate,
  ],
  supportedLocales: const <Locale>[
    Locale('en', ''),
    Locale('ar', ''),
  ],
  home: ...
)

import 'package:google_map_location_picker/google_map_location_picker.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

LocationResult result = await LocationPicker.pickLocation(context, apiKey);

Note

The following permissions are not required to use Google Maps Android API v2, but are recommended.

android.permission.ACCESS_COARSE_LOCATION Allows the API to use WiFi or mobile cell data (or both) to determine the device’s location. The API returns the location with an accuracy approximately equivalent to a city block.

android.permission.ACCESS_FINE_LOCATION Allows the API to determine as precise a location as possible from the available location providers, including the Global Positioning System (GPS) as well as WiFi and mobile cell data.

You must also explicitly declare that your app uses the android.hardware.location.network or android.hardware.location.gps hardware features if your app targets Android 5.0 (API level 21) or higher and uses the ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission in order to receive location updates from the network or a GPS, respectively.

<uses-feature android:name="android.hardware.location.network" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false"  />

The following permissions are defined in the package manifest and are automatically merged into your app’s manifest at build time. You don’t need to add them explicitly to your manifest:

android.permission.INTERNET Used by the API to download map tiles from Google Maps servers.

android.permission.ACCESS_NETWORK_STATE Allows the API to check the connection status in order to determine whether data can be downloaded.
