init static method

Future<void> init({
  1. required String? serverUrl,
  2. Set<SAAutoTrackType>? autoTrackTypes,
  3. Set<SANetworkType>? networkTypes,
  4. int flushInterval = 15000,
  5. int flushBulkSize = 100,
  6. bool enableLog = false,
  7. bool javaScriptBridge = false,
  8. bool encrypt = false,
  9. AndroidConfig? android,
  10. IOSConfig? ios,
  11. VisualizedConfig? visualized,
  12. bool heatMap = false,
  13. Map? globalProperties,
})

初始化神策 SDK。 用户需要尽可能早的调用该初始化方法，建议在 main() 方法中，不过至少要保证 Flutter 项目这段代码执行完毕：

WidgetsFlutterBinding.ensureInitialized()

参考示例如下：

void main(){
  WidgetsFlutterBinding.ensureInitialized();
  SensorsAnalyticsFlutterPlugin.init(...);
  runApp(MyApp());
}

如果你不用 Flutter 全埋点功能，也可以放在合适位置进行初始化。另外如果 Native 中也执行了初始化，会以最先执行的为准。

参数定义如下：
serverUrl: 数据接收地址
autoTrackTypes: 全埋点类型
networkTypes: 数据上报的网络条件
flushInterval: 数据上报的时间间隔，单位是毫秒，默认是 1500ms
flushBulkSize：触发上报逻辑的事件数目，默认是 100 条
enableLog：是否开启本地 log，该配置只在 debug 阶段有效
javaScriptBridge: 是否支持 H5 打通，Android 中需要和 AndroidConfig.jellybean 配合使用
encrypt: 是否支持加密，Flutter 中初始化只支持 RSA+AES 加密
android: Android 部分特有的配置
ios: iOS 部分特有的配置
visualized: 可视化全埋点部分特有的配置，Flutter 暂不支持可视化，该配置会影响 Native
heatMap: 是否开启点击图，Flutter 暂不支持点击分析功能，该配置会影响 Native
