Я оцениваю Плагин Firestore для Flutter .
Этот фрагмент работает, как и ожидалось, он вставляет запись в пожарную, когда нажата плавающая кнопка:
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),
),
}
}
При работе с flutter run
на консоли отображается предупреждение:
W/Firestore(31567): (0.6.6-dev) [Firestore]: The behavior for java.util.Date objects stored in Firestore is going to change AND YOUR APP MAY BREAK.
W/Firestore(31567): To hide this warning and ensure your app does not break, you need to add the following code to your app before calling any other Cloud Firestore methods:
W/Firestore(31567):
W/Firestore(31567): FirebaseFirestore firestore = FirebaseFirestore.getInstance();
W/Firestore(31567): FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
W/Firestore(31567): .setTimestampsInSnapshotsEnabled(true)
W/Firestore(31567): .build();
W/Firestore(31567): firestore.setFirestoreSettings(settings);
W/Firestore(31567):
W/Firestore(31567): With this change, timestamps stored in Cloud Firestore will be read back as com.google.firebase.Timestamp objects instead of as system java.util.Date objects. So you will also need to update code expecting a java.util.Date to instead expect a Timest
Есть способ настроить экземпляр FirebaseFirestore и таким образом исправить эту проблему с настройками даты?
