Question

我有一个习惯来跟踪功能运行了多长时间，在react native中，我可以将console.time与react-native-console-time-polyfill一起使用

myFunction(){
  console.time("Func Foo")
  //any logic here
  console.timeEnd("Func Foo")
}

如何使用Flutter做到这一点？

Answer 1

检查此URL。

您可以在flutter中获取所有调试信息

https://flutter.dev/docs/testing/debugging

它将为您提供帮助。

Answer 2

也许您可以尝试一下。

void main() async {
  var dateTimeNow = DateTime.now();

  await someExecution(); // call your function here.

  var dateTimeAfterExecution = DateTime.now();

  var difference = dateTimeAfterExecution.difference(dateTimeNow);
  print(difference.inMilliseconds);
}

Answer 3

尝试一下

myFunction(){
  var oldTime = DateTime.now().millisecondsSinceEpoch;
  //any logic here

  // total time taken to run the logic would be
  print("time = ${DateTime.now().millisecondsSinceEpoch - oldTime} ms");
}
