map

A new Flutter application.

Getting Started

This project is a starting point for a Flutter application.

A few resources to get you started if this is your first Flutter project:

• Lab: Write your first Flutter app
• Cookbook: Useful Flutter samples

For help getting started with Flutter, view our online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.

flutter_google_Map

Step1. 添加Google Maps Flutter plugin 和之前Day25-在iPhone上實現Video Player添加video_player plugin的做法一樣在pubspec.yaml加入google map plugin dependencies

dependencies: flutter: sdk: flutter google_maps_flutter: ^0.5.11 //加這行

Step2. 取得Google Map API key 可參考https://ithelp.ithome.com.tw/articles/10227736

Step3. 添加API key iOS: iOS添加API key，我們需要編輯ios/Runner/AppDelegate.swift文件 加入以下代碼，要記得補上剛剛申請的API key

  import GoogleMaps //加這行

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

編輯ios/Runner/Info.plist文件，裡加入以下 請注意 下面兩行都要加入

  <key>io.flutter.embedded_views_preview</key>
  <true/>

Android: Android添加API key，我們需要編輯android/app/src/main/AndroidManifest.xml文件

      <manifest ...
      
       <!--    Google Map 需要手動增加下面兩個 uses-permission-->
      <uses-permission android:name="android.permission.INTERNET" />
      <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
      
      <application ...
          <meta-data android:name="com.google.android.geo.API_KEY"
                     android:value="YOUR KEY HERE"/>
                     ........

這樣前置作業就完成了！

Permission 請參考： https://blog.csdn.net/u013425527/article/details/98938611

pubspec.yaml加入

  dependencies:
  flutter:
    sdk: flutter
  #    动态权限申请
  permission_handler: '^3.2.0'

Android: Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 28:

    android {
      compileSdkVersion 28
      ...
    }

在 gradle.properties

  android.enableJetifier=true
  android.useAndroidX=true

android/app/src/main/AndroidManifest.xml文件

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

iOS: Add permission to your Info.plist

    <!-- permission 加入下面兩行 start-->
    <key>NSLocationWhenInUseUsageDescription</key>
    <string>When In Use Permission</string>
    <key>NSLocationAlwaysUsageDescription</key>
    <string>Always Permission</string>
    <key>NSLocationAlwaysAndWhenInUsageDescription</key>
    <string>Always And In Use Permission</string>
    <key>EnableBackgroundLocationUpdates</key>
    <true/>
    <!-- permission 加入下面兩行 end-->

Google ADS Mob:

pubspec.yaml加入

#20200615 Google ADS
firebase_admob: ^0.9.0+1
ads: ^1.7.3

Android:

在 android/app/src/main/AndroidManifest.xml文件

  <manifest>
    <application>
        <!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>
        <meta-data
          android:name="com.google.android.gms.ads.AD_MANAGER_APP"
          android:value="true"/>
    </application>
   </manifest>

android/build.gradle

   buildscript {
      .........

      dependencies {
         .........
          //#20200615 Google ADS  Add the following line:
          classpath 'com.google.gms:google-services:4.3.3'
      }
  }

iOS:

Info.plist 增加

 <!--20200615 Google ADS Google ADSMob 加入下面兩行 start-->
<key>GADApplicationIdentifier</key>
<string>ca-app-pub-3940256099942544~1458002511</string>
<key>io.flutter.embedded_views_preview</key>
<true/>
<!--20200615 Google ADS Google ADSMob 加入上面兩行 end-->

去https://console.firebase.google.com/u/0/ 建立專案 下載 GoogleService-Info.plist 使用XCode 將GoogleService-Info.plist 放入到Runner資料夾， 否則會因為找不到GoogleService-Info.plist導致fire_base connect fail 無法開啟app

  GoogleService-Info.plist

下載 GoogleService-Info.plist 可參考
