我正在评估这个问题

此代码段按预期工作,当按下中的浮动按钮时,它会将一条记录插入firestore:

import 'package:flutter/material.dart';
import 'package:cloud_firestore/cloud_firestore.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  Firestore firestore;

  _MyHomePageState() {
    firestore = Firestore.instance;
  }

  void _addBoard() {
    setState(() {
      _counter++;
      firestore.collection("boards").document().setData({ 'name': 'mote_$_counter', 'descr': 'long descr $_counter' });
    });
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text(widget.title),
      ),
      body: new Center(
        child: new Column(
         mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            new Text(
              'You have pushed the button this many times:',
            ),
            new Text(
              '$_counter',
              style: Theme.of(context).textTheme.display1,
            ),
          ],
        ),
      ),
      floatingActionButton: new FloatingActionButton(
        onPressed: _addBoard,
        child: new Icon(Icons.add),
      ), 
  }
}

有一种方法可以配置FirebaseFirestore实例,从而通过日期设置解决此问题?

应该在版本0.8.2中解决


有关如何使用设置的详细信息,请参见。

问题已从cloud_firestore 0.8.2中解决,首先将
pubspec.yaml
中的依赖项升级为:

dependencies:
  cloud_firestore: ^0.8.2+1
返回Future,因此必须在异步函数中调用它

这足以使works成为示例代码:

void main() async {
  final Firestore firestore = Firestore();
  await firestore.settings(timestampsInSnapshotsEnabled: true);

  runApp(new MyApp());
}
然后,在实际添加文档时,您显式地添加了一个
createdAt
(或任何您想称之为的)字段,如下所示:

    Firestore.instance
        .collection('customer')
        .add({
      "name": customerNameController.text,
      "createdAt": FieldValue.serverTimestamp()
    }).then((res) { ...

我也面临着同样的问题,GitHub中有一个问题打开了,但从未接近,所以我不喜欢这样的声音,但我一直在等待这个问题的任何进展@attdona-你能用
wait firestore.settings(timestampsInSnapshotsEnabled:true)展示一下你是如何修改现有代码的吗东西。我非常怀疑如何使用它。在这里-在使用部分没有提到关于
wait firestore.settings(timestampsInSnapshotsEnabled:true)的内容东西。所以,我有点搞不清楚该用什么。链接已经关闭了。请将解决方案放在这里,而不是提供其他页面的链接。
    Firestore.instance
        .collection('customer')
        .add({
      "name": customerNameController.text,
      "createdAt": FieldValue.serverTimestamp()
    }).then((res) { ...
