Polymaker #

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.

Tools Feature: #

• Get Current Location
• Entering Edit Mode
• Closing Edit Mode
• Done Editing

ANDROID

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>"/>
	<meta-data  android:name="com.google.android.gms.version"
		android:value="@integer/google_play_services_version" />
</application>

Setup your SDK Version to the latest in android/app/build.gradle

compileSdkVersion 29
....
defaultConfig {
  ....
  targetSdkVersion 29
  ....
}

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; 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/>

How To Use #
