Polymaker is a flutter package to make it easier to map polygon locations in Google Maps, because the appearance is realtime when in Edit Mode, so we know the exact position without guessing through the backend system. Polymaker can be run with only one line of code, and returns the location's List value.
- Get Current Location
- Entering Edit Mode
- Closing Edit Mode
- Done Editing
- Undo Editing to Previous Location
- Realtime polygon to view result
- Custom Marker as Pointing Number
- Point Distance
- Tracking Mode LINEAR & PLANAR
- Custom Map Type
You must enable some API in google cloud to use this features
- Google Maps for Android/iOS
Adding Permission in android/app/src/main/AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Insert Google Maps Key in android/app/src/main/AndroidManifest.xml
<application
android:name="io.flutter.app.FlutterApplication"
android:label="example"
android:icon="@mipmap/ic_launcher">
.....
<meta-data android:name="com.google.android.geo.API_KEY"
android:value="<YOUR API KEY>"/>

</application>
Setup your SDK Version to the latest in android/app/build.gradle
compileSdkVersion 29
....
defaultConfig {
....
targetSdkVersion 29
....
}
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
; you need also to define NSLocationWhenInUseUsageDescription
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs your location to test the location feature of the Google Maps location picker plugin.</string>
<key>io.flutter.embedded_views_preview</key>
<true/>
Using polymaker is very easy and only needs to use one line of code
import 'package:polymaker/polymaker.dart' as polymaker;
// Open polymaker and get return List<LatLng>
var result = await polymaker.getLocation(context);
