GrowingIO 埋点（目前仅Android端）

注册好 GrowingIO 账号后，选择应用管理 → 添加应用 → 选择第三方平台，Flutter 分别选择运行平台为 Android 、 ios → 填写应用名称 → 按照官方给予的SDK安装步骤一次操作即可：

1、集成Flutter插件

1.1 添加依赖，编辑 pubspec.yaml 文件：

    dependencies:
        flutter_growingio_track: ^2.6.0

1.2 安装插件

    flutter pub get

1.3 添加导包代码使用埋点插件，在需要自定义事件或者变量的页面引入包依赖

    import 'package:flutter_growingio_track/flutter_growingio_track.dart';

2、集成Android原生 SDK

2.1 导入SDK

编辑 app/build.gradle 文件中添加 com.growingio.android 插件、vds-android-agent 依赖和对应的资源；

    apply plugin: 'com.android.application'
    android {
        defaultConfig {
            //添加 growingio_project_id 和 growingio_url_scheme （平台会自动生成）
            resValue("string", "growingio_project_id", "8293ef4552c9be54")
            resValue("string", "growingio_url_scheme", "growing.c8a606bcae023aac")
        }
        dependencies{
            // 添加 （平台会自动生成）
            implementation 'com.growingio.android:vds-android-agent:track-2.8.13'
        }
    }

2.2 添加 URLScheme

把URL Scheme 添加到您的项目，以便我们唤醒您的程序，进行圈选。将该产品的 URLScheme 添加到你的 AndroidManifest.xml 中的 LAUNCHER Activity 下。例如

    <?xml version="1.0" encoding="utf-8"?>
        <manifest xmlns:android="http://schemas.android.com/apk/res/android"
            package="com.example.growingio.testdemo">
            <!-- 添加权限 -- >
            <uses-permission android:name="android.permission.INTERNET" />
            <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
            <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
            <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
            <uses-permission android:name="android.permission.READ_PHONE_STATE" />
            <application
                android:AllowBackup="true"
                android:icon="@mipmap/ic_launcher"
                android:label="@string/app_name"
                android:roundIcon="@mipmap/ic_launcher_round"
                android:supportsRtl="true"
                <!--请注意<application/>标签中的name属性值, 必须为您的Application类-->
                android:name=".MyApplication"
                android:theme="@style/AppTheme">
                <activity android:name=".MainActivity">
                    <intent-filter>
                        <action android:name="android.intent.action.MAIN"/>
                        <category android:name="android.intent.category.LAUNCHER"/>
                    </intent-filter>
                    <!--添加一整个 intent-filter 区块，并确保其中只有一个 data 字段-->
                    <intent-filter>
                        <data android:scheme="growing.c8a606bcae023aac"/>
                        <action android:name="android.intent.action.VIEW" />
                        <category android:name="android.intent.category.DEFAULT" />
                        <category android:name="android.intent.category.BROWSABLE" />
                    </intent-filter>
                </activity>
            </application>

        </manifest>

2.3 初始化 SDK

请点击 Android studio 中的 Sync Now 按钮依赖 sdk 成功后，按照以下照示例代码修改您的 Application 文件：

    import com.growingio.android.sdk.collection.Configuration;
    import com.growingio.android.sdk.collection.GrowingIO;
    public class MyApplication extends Application {
        @Override
        public void onCreate() {
            super.onCreate();
            GrowingIO.startWithConfiguration(this, new Configuration()
                    .setTestMode(BuildConfig.DEBUG)
                    .setDebugMode(BuildConfig.DEBUG)
                    .setChannel("XXX应用商店")
                );
        }
    }

注意： 如果找不到，可以在 android/app/src/main 下新建项目目录：若 applicationId 为com.example.growingio.testdemo ，则新建目录为 com/example/growingio/testdemo , 在该目录下新建一个名为 MyApplication的Application 文件(完整目录为：android/app/src/main/com/example/growingio/testdemo/MyApplication.java)

2.4 相应的页面或组件中，定义上传事件

    自定义事件
    GrowingIO.setEvar({
        'testKey': 'testValue', 'testNumKey': 2333.0
    });

到此，GrowingIO埋点Android基本完成，但是一定要注意，清楚项目build包，并重启项目，多操作几次才能成功（本人需要关闭编辑器，再次启动项目才成功，坑惨了。。。。）

3、集成 Ios原生 SDK（参考：https://growingio.kf5.com/hc/kb/article/1334925/）

3.1、添加依赖 （通过 Cocoapods 快速添加）

3.1.1、在项目的 ios 目录下的 Podfile 文件中添加 pod "GrowingCoreKit"

    // 我的项目中的 Podfile 文件内容 
    # Uncomment this line to define a global platform for your project
    # platform :ios, '9.0'
    install!'cocoapods',:deterministic_uuids=>false
    platform :ios, '8.0'

    # CocoaPods analytics sends network stats synchronously affecting flutter build latency.
    ENV['COCOAPODS_DISABLE_STATS'] = 'true'

    project 'Runner', {
    'Debug' => :debug,
    'Profile' => :release,
    'Release' => :release,
    }

    def parse_KV_file(file, separator='=')
    file_abs_path = File.expand_path(file)
    if !File.exists? file_abs_path
        return [];
    end
    generated_key_values = {}
    skip_line_start_symbols = ["#", "/"]
    File.foreach(file_abs_path) do |line|
        next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
        plugin = line.split(pattern=separator)
        if plugin.length == 2
        podname = plugin[0].strip()
        path = plugin[1].strip()
        podpath = File.expand_path("#{path}", file_abs_path)
        generated_key_values[podname] = podpath
        else
        puts "Invalid plugin specification: #{line}"
        end
    end
    generated_key_values
    end

    target 'Runner' do
    # Flutter Pod

    copied_flutter_dir = File.join(__dir__, 'Flutter')
    copied_framework_path = File.join(copied_flutter_dir, 'Flutter.framework')
    copied_podspec_path = File.join(copied_flutter_dir, 'Flutter.podspec')
    unless File.exist?(copied_framework_path) && File.exist?(copied_podspec_path)
        # Copy Flutter.framework and Flutter.podspec to Flutter/ to have something to link against if the xcode backend script has not run yet.
        # That script will copy the correct debug/profile/release version of the framework based on the currently selected Xcode configuration.
        # CocoaPods will not embed the framework on pod install (before any build phases can generate) if the dylib does not exist.

        generated_xcode_build_settings_path = File.join(copied_flutter_dir, 'Generated.xcconfig')
        unless File.exist?(generated_xcode_build_settings_path)
        raise "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first"
        end
        generated_xcode_build_settings = parse_KV_file(generated_xcode_build_settings_path)
        cached_framework_dir = generated_xcode_build_settings['FLUTTER_FRAMEWORK_DIR'];

        unless File.exist?(copied_framework_path)
        FileUtils.cp_r(File.join(cached_framework_dir, 'Flutter.framework'), copied_flutter_dir)
        end
        unless File.exist?(copied_podspec_path)
        FileUtils.cp(File.join(cached_framework_dir, 'Flutter.podspec'), copied_flutter_dir)
        end
    end

    # Keep pod path relative so it can be checked into Podfile.lock.
    pod 'Flutter', :path => 'Flutter'
    // 微信 SDK
    pod 'WechatOpenSDK'
    // GrowingIO埋点 SDK
    pod 'GrowingCoreKit'

    # Plugin Pods

    # Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
    # referring to absolute paths on developers' machines.
    system('rm -rf .symlinks')
    system('mkdir -p .symlinks/plugins')
    plugin_pods = parse_KV_file('../.flutter-plugins')
    plugin_pods.each do |name, path|
        symlink = File.join('.symlinks', 'plugins', name)
        File.symlink(path, symlink)
        pod name, :path => File.join(symlink, 'ios')
    end
    end

    post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
        config.build_settings['ENABLE_BITCODE'] = 'NO'
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
        end
    end
    end

3.1.2、执行 pod install 或 pod update 更新 pod依赖库。

    根据你项目的环境可能会报各种错误，百度解决的。

3.1.3、 添加 URL Scheme

    growingIO  会自动生成相应的 URL Scheme
    Xcode中，找到Targets 下面的info选项卡，在URL Types中添加对应的url scheme

注意： growingIO 对 IOS 端的埋点数据信息采集 会有 1~2个 小时的延迟（即不能及时在平台端看见访问信息），但安卓端貌似没有这个问题
