如何使用Flutter在后台读取加速度计

如何解决如何使用Flutter在后台读取加速度计

我正试图从隔离功能中获取加速度传感器数据，该功能是在后台处理代码的独立方法（独立于UI）。但是我没有设法使其工作：-/。加速度计数据可以从主要功能中很好地获取，但不能从隔离功能中获取。

这是代码：

import 'dart:io';
import 'package:Flutter/foundation.dart';
import 'package:Flutter/material.dart';
import 'package:sensors/sensors.dart';



void main() async{
  WidgetsFlutterBinding.ensureInitialized();

  print('Going to create new Isolate');
  compute(getAccelerometer,null);
  print('New Isolate Created and it started his work');


  userAccelerometerEvents.listen((UserAccelerometerEvent event) {
    print('main : $event');
  });


  /*
  After executing all the instructions of main method app will killed,so to pause the main method(using stdin.first),so that we can wait in case
  "new Isolate" not finish yet.
  Press Enter to move forward
   */
  await stdin.first;


  print('new Isolate killed');
}

void getAccelerometer(String args) async {

  print("start accelerometer recording");

  for(int i = 0; i<1000; i++) {
      userAccelerometerEvents.listen((UserAccelerometerEvent event) {
      print('isolate : $event');
    });

    }

  }
