Change your browser. I was previously trying on Safari. Then. I used Chrome. It got solved.

Yep the cors thing did it for me!

Disabling CORS worked for me too, Thank you.

Can’t believe that deactivating adblocker fixed the issue…

Today the problem has gone. I looked in the status info. Yesterday they had issues. Not sure what that all means. But I close the issue.

how you solve it ?

On the day it was the problem, the Firebase status indicated issues. My problem gone on its own the next day, and the Firebase status did not show  issues on that day. So I interpreted it that my problem resulted from the Firebase  issues.

@victorshn those warnings are safe to ignore

@fmatosqg flutter shows only that build error, how to get more details?

I am trying to allow users to sign in from the app to the firsebase

@nassimbjf this looks like an issue I had before, it’s something to do with how your imports are set

import ‘package:flutter/material.dart’;
import ‘login_page.dart’;
import ‘auth.dart’;
import ‘root_page.dart’;

yeah, so make them all full paths, so in other words, have them all start with package: followed by the path to the dart file

I’m really so happy because I am in this group chat

i am getting input from a textfield with maxlines if the user press enter it moves to next line(this works when user is typing) buh it does not appear on diffirent lines when I convert it to the pdf. any help

Hello, I want a step by step tutorial to integrate Firebase Auth in my Flutter app. Can anyone help me find out?

@saeedjassani I’m on the phone can’t search. There used to be a codelab for that. If you can’t find it to through github.com/flutter and check the chat sample app

@saeedjassani Here’s the codelabs for firebase, but I think it’s for firestore

you can’t partially redirect a constructor, you have to forward all of those args through

onTap: () => Navigator.of(context).push(new MaterialPageRoute(
                      builder: (BuildContext context) => new Detail(
                          id: id,
                          name: name,
                          image: image,

@abidaparveen Thanks for reply. What u are showing seems just push to next detail. How ever I wanna ask something like this:

yes this would refresh your page each time the user scroll through pages

How avoid that anyway? I dont want the data always refresh, that is too slow

@jinfagang try using different approach … you may end up spending too much time on it

Yeah, struggling on it. I will give it up if there not other solution

there are more good people here .. someone will help

Jin can you show how is data refreshed

Well, I am previously an iOS developer

class _MyBodyState extends State<MyBody> {
  static List allGoods = [];
  int allGoodsPageNo = 1;

  RefreshMode loading = RefreshMode.idle, refreshing = RefreshMode.idle;

  Future<Null> getAllGoods() async {
    print('fuck');
    var _tbItemsUrl =
        "http://loliloli.pro/api/v3/taobao_items_hitui?page_no=$allGoodsPageNo&per_page=30";
    print(_tbItemsUrl);
    var response = await http.get(
      Uri.encodeFull(_tbItemsUrl),
    );
    var data = json.decode(response.body);
    print(data['data'][0]);
    print(data['status']);
    this.setState(() {
      allGoods.addAll(data['data']);
      this.allGoodsPageNo += 1;
      print("=> we got goods: ${allGoods.length}");
    });
  }

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    // If it is singleton, then allGoods should not be none after first run
    if(allGoods != null || allGoods.length != 0){
      print("不要加载了，已经加载过一次了。");
    }else{
      getAllGoods();
    }
  }

Already tried that: if(allGoods != null || this.allGoods.length != 0){ it always return true

static List allGoods = [];

and never use this with static variables

How to change package name in flutter

Hello! How can I create a landscape screen?

I believe you can make a container decorator, that when implemented with a custom paint you can draw over other components

Hey I am new to flutter. I am getting this error after upgrade flutter

List<List> favUrls = [];

var photo = favUrls[index1][‘featured_img’]; favid = favUrls[index1][‘ID’];

@AshokVonteddu Thanks, got it working!

Not just 2 lines show the complete Class….

Welcome @RobertBrunhage

I need some help, I have a network image in my profile, the weird thing is that it downloads the image multiple times depending on which bottomnavigation I select:

new FadeInImage.memoryNetwork(
                  placeholder: kTransparentImage,
                  image: profilePictureUrl,
                  fit: BoxFit.cover,
                ),

So first it loads when I start the app, then it loads each time I enter a different bottomnavitem ex: my home feed or new feed. This is making my firebase storage read quata get reached really fast on only 1-2 images top. Anyone got any idea on how to fix this?

To upgrade my app’s flutter version to Beta 3 i should change to the dev channel?

Should the app behave like this? because I don’t want it to run my ui code in profile when I navigate to new feed or any other tab. This runs my network image on everyplace I use it which eats up my read on firebase storage whiting 2 hours of developing…

I’m working on app where above Camera view I need to show something. But, whenever I’m trying to build app I’m getting these errors…

There are 2 solutions available to ur problem.
1) Save most often used image on File.
2) Use image caching library

@hackerhgl The problem isn’t about me downloading a file I want, It is that it does it when I don’t want it to.

This is my home which holds my navigations etc:

new Stack(
          children: <Widget>[
            new Offstage(
              offstage: Home.index != Constants.HOME,
              child: new TickerMode(
                enabled: Home.index == Constants.HOME,
                child: new HomeFeed(),
              ),
            ),
            new Offstage(
              offstage: Home.index != Constants.NEW,
              child: new TickerMode(
                enabled: Home.index == Constants.NEW,
                child: new NewFeed(),
              ),
            ),
            new Offstage(
              offstage: Home.index != Constants.UPLOAD,
              child: new TickerMode(
                enabled: Home.index == Constants.UPLOAD,
                child: new UploadFeed(),
              ),
            ),
            new Offstage(
              offstage: Home.index != Constants.FAVORITES,
              child: new TickerMode(
                enabled: Home.index == Constants.FAVORITES,
                child: new HomeFeed(),
              ),
            ),
            new Offstage(
              offstage: Home.index != Constants.PROFILE,
              child: new TickerMode(
                enabled: Home.index == Constants.PROFILE,
                child: new ProfileFeed(),
              ),
            ),
          ],
        ),

All of these: HomeFeed(), NewFeed(), ProfileFeed() etc etc is all getting called when I open the app and all of them are called when I navigate to one of them, instead of only running the one I navigate to…

Do you mean all your Feeds are rendered when you open the app?

yeah and all of them a rendered when I press on one of them also. So pretty much all of them are rendered each time I open the app and each time I navigate with the bottomnavbar

            new Offstage(
              offstage: Home.index != Constants.PROFILE,
              child: new TickerMode(
                enabled: Home.index == Constants.PROFILE,
                child: Home.index == Constants.PROFILE ? new ProfileFeed() : new Container(child: null),
              ),
            ),

@hackerhgl Thanks! It seems like that is working, will test it out more while developing but I think that did the trick, Thanks so much!

If you wanna preserve State Then

Class FeedPage {
 [State Logic]

 Build() {
  if (enabled) 
    return Page;
 } else
    return new Container(child: null);

}

@hackerhgl Sorry, haven’t done that before. Could you give a more detailed example?

            new Offstage(
              offstage: Home.index != Constants.PROFILE,
              child: new TickerMode(
                enabled: Home.index == Constants.PROFILE,
                child: new ProfileFeed(enable: Home.index == Constants.PROFILE),
              ),
            ),

What should I do with the final firebase app variable?

Well i don’t known how you design the architecture.
Now you have to figure out that part.

It seems to only render what I have in the HomeFeed() and not the others

Yeah but when I navigate to profileFeed() it won’t render the profileFeed at all because enable bool is false

does “Home.index” change when you navigate to other FeedScreen

Yeah I added a breakpoint and it seems that it returns true on the one I navigate to but then inside that class it says false on the enable var

Yup, you can’t change the value of final variable…

changed it to without final but still it seems that it is passing true to the profile constructor but still says false on enable

Its Because you preseves the state Thats why new Objects aren’t created….

but it’s nothing to preserve because it never once runs the code to generate the UI because it always returns the container with null child

you have design your code differently.

hello, buttom navigationBar is kinda too big hw do i adjust its size

I have a ListView builder where I have some items that i can increment or decrements some values, how can i preserve the state of the actions in the ui because when I scroll the list all items out of view gets reset (I have the data but I am asking about preserving the state of the ui)

hey guys, do you know how to do outset border shapes? basically I want to have a bottom app bar with two «ramps» going up, instead of down, like in the I/O example

good morning everyone! I’m trying to debug my app, and the breakpoints aren’t stopping at certain places. It is because they’re in an async function? The function appears to be working, but debugPrint statements within it aren’t printing.

@axmccx Do you have any idea ho can I import images from firebase in the Storage?

@nassimbjf sorry, I don’t know. I haven’t touch any of the Storage stuff yet, just learning the Auth and firestore right now.

Hi Everyone. Would Like to know if there is a problem with firebase_auth 0.5.9 + firebase_storage 0.3.4 + pod 1.5.2 with iOs and some deprecated functions/properties?

Does anyone knows how to import images from firebase in the Storage

@axmccx hello Alex. DO you have any problem? are you using an iOs Emulator?

result.success(snapshot.getDownloadUrl().toString());

yes they prevent me from running my project

@nassimbjf ahah, yeah, I would pick that apart :p

@ramah that’s odd, I wouldn’t expect a deprecation warning to cause a build failure

pub-cache/hosted/pub.dartlang.org/firebase_storage-0.3.4/ios/Classes/FirebaseStoragePlugin.m:190:43: error: property ‘downloadURL’ not found on object of type ‘FIRStorageMetadata ‘

do you use any objects of type FIRStorageMetadata and are trying to downloadURL on it?

In fact i’ just added in the pubspec.yaml those line and compilation failed

and you’re adding the appropriate imports?

I think that if the project did not build no need to imports theme in dart files?

uh, pretty sure you need to import what you’re using

@ramah Try to remove the ‘^’ arrow on all of them and then try to decrease the versions one by one to see if that is faulty

Hi!
I have a custom StatefulWidget inside a TabBarView how do I preserve its status when I change tab.
I used a PageStorageKey and it keeps the scrolling position but it loses everytime the state of my custom StatefulWidget.

hey there, i have a cloud firestore connection, but changes only take effect on «Text» elements. Icons won’t change. Is there something to be implemented to notify the Icons to be redrawed?

Can I use Image.asset() as a placeholder for FadeInImage.memoryNetwork() ?

How can I access methods and setstate of another class in another file?

@zoechi please my tabs recreate and reloads the data in it each time I navigated to and fro a new tab, is there anyway to fix it?

Hi guys How can I load images from firebase

@nassimbjf Do you have the url of the image?

@RobertBrunhage Have you uploaded the image?

I want to use my own images

this is the code I use to upload to firebase storage:

    var uuid = new Uuid();
    FirebaseUser user = await FirestoreUtil.getUid();
    User userObject = await FirestoreUtil.downloadUser(user.uid);
    final StorageReference ref = FirebaseStorage.instance.ref().child(user.uid + "/"+ uuid.v1().toString());
    final StorageUploadTask uploadTask = ref.put(imageFile);
    final Uri downloadUrl = (await uploadTask.future).downloadUrl; //Uploads to FirebaseStorage

Where I should paste this?

as you can see I am getting a downloadUrl which I can put in a networkimage or upload to firestore/realtime database

Do you uploaded the image to the storage with code or have you done it manually?

If you go into storage in firebase and press on the name of the image. To the right you will see a small image of the one you have uploaded right?

in the file location dropdown you can find a download url

Does anyone know how to preserve the state of ui when scrolled out of view in a ListView ?

@RobertBrunhage This code is to upload to firebase right ?
var uuid = new Uuid();
FirebaseUser user = await FirestoreUtil.getUid();
User userObject = await FirestoreUtil.downloadUser(user.uid);
final StorageReference ref = FirebaseStorage.instance.ref().child(user.uid + «/»+ uuid.v1().toString());
final StorageUploadTask uploadTask = ref.put(imageFile);
final Uri downloadUrl = (await uploadTask.future).downloadUrl;

@nassimbjf That code is specific to my project because I have created my own classes

@axmccx @zoechi No evolution. Now folllowing the tutorial for flutter and firebase I have this self->

What about just loading the images

@nassimbjf You just take the Url as I said before and you put it in the Image.network() widget

@RobertBrunhage Do you have any idea how can I create my own Package?

Hello I’m looking for a working set of firebase/plugins building for an ios application (auth + storage + database) thx

Flutter NEWBIE here, I built a little sample app and ran it on iOS Simulator but it looks like Material Design, is there a simple way to make it look like an iOS app? Thank sin advance!

Do you have android studio installed?

I thought it was added by it

yeah, so just change the part of the command «%USERPROFILE%.androiddebug.keystore»

The constructor returns type ‘dynamic’ that isn’t expected type ‘Widget’

Anyone found a way to force Android Studio Flutter extension to create Dart 2 boiler plate from shortcuts such as «stful»?

i’m getting these error when i’m running a app……any help ?

if it start typing stf I can hit enter and the boilerplate gets added

@axmccx thank you very much

@Donistivanov you’re very welcome

does it create Dart 1 style code? i.e. return new Container(); in the Widget build

Hi, I’m trying to code the following in flutter:
https://goo.gl/rGjU82
The code used here does not contain ‘new’ keyword, however my program requires me to use new keyword everywhere. Can anyone help?

when I run my app, the emulator goes straight to «app» has stopped working. Android studio’s console shows no errors, the Flutter inspector opens up and no signed of any problems. Does anyone have any advice on how to debug this?

please how do i retain my appstate when i navigate to a new tab?

@axmccx , my Android Studio is at the latest version, but it still expects the new keyword… the error message im getting is ‘function not defined’. Any clue on where Im going wrong?

make sure everything is up to date

@ashwanth1109 File -> Settings -> Languages & Frameworks -> flutter -> ‘Run application in Dart 2.0’ enable dart 2.0

@axmccx
please how do i retain my appstate when i navigate to a new tab?
it totally recreates the state

@ashwanth1109 mine, Flutter version 0.3.2, yours is 0.0.21? try running the command flutter upgrade

@RobertBrunhage , I updated my settings in flutter to enable dart 2.0, so now my app is running successfully but I still get errors for not using new keyword.
Then I updated as per @axmccx instructions and the errors are all gone, so thanks guys
@axmccx @RobertBrunhage

@ashwanth1109 glad to hear it!

@nassimbjf AsymmetricView is not a widget from the Flutter framework, it looks like something they put together for that demo/codelab, have you checked if it’s in the codelab repo/files?

@axmccx try to systematically place out break point from your application start and deeper in to the app depending on what kind of app

@axmccx Ohh didn’t see you got it working, nice!

yeah! it just started working again out of nowhere, that’s what’s frustrating

@axmccx If it happens again:
Try doing a flutter clean before flutter run.
Try running flutter run -v for verbose mode which might have more errors logged
Try checking adb logcat for an error on the android side that never shows up in the flutter logs

thanks for the suggestions @xqwzts I’ll try next time it happens

@mtellect What app state are you trying to retain?

i have 4tabs say «A, B, C, D» with data in each, when you move from A to B or A to C, the state is lost, kinda like the widget is rebuilt

A RenderFlex expected a child of type RenderBox but received a child of type RenderSliverPadding.

Can anybody give some help with slivers ? What are they, how do they work ? I am having a lot of trouble with them and I can’t wrap my head around them.

@xqwzts What does my error actually mean ?

Did you try to place a SliverPadding widget somewhere that isn’t a CustomScrollView?

I have a CustomScrollView and inside it I put 3 SliverToBoxAdapter items and one SliverPadding which has as a child a SliverList

[The non-scrollable widgets are boxes (inherting from RenderBox), the scrollable ones are Slivers]

That depends on the question, but feel free to just ask it, and hopefully someone with an answer will come along

I have drawer inside statefulwidget

Have you placed the drawer in a Scaffold?

@mtellect Where do you call the classes? because I simply fixed the issue with doing ‘final HomeFeed _homeFeed = new HomeFeed();’ in the class that holds my navbar and then using _homeFeed instead of doing new HomeFeed() each time I go to the tab.

@RobertBrunhage let me try this out

@marica27 Thank you , is it legal to use it right?

@xqwzts I got it. I was using a ListView inside a CustomScrollView. I replaced the ListView with Column and it works. Thanks for your time. I really appreciate you investing your time in helping the community.

@radiKal07 The silver equivalent of ListView is SliverList

Yes, but SliverList was not working also, maybe because it was inside a non-sliver parent.

Hmm, a CustomScrollView is a sliver parent though

someone use drawer inside statefullwidget ?

do you guys put your Google Functions code in the same project folder as flutter?

@RobertBrunhage ..didn’t work…on page A, and B scroll widget went back to the top

@Donistivanov I have all Firebase server side stuff in a sibling project to my firebase project

@zoechi I have 4 tabs «A,B,C,D» each has data being loaded from the db @initstate, now when I move from A to B or either tabs , the widgets in all are recreated , how can I stop t?

@zoechi hmm makes sense. Thanks!

I am using the ButtomNavigationBar with IconButtons In It, hw can I adjust its height, its too big OR I can’t do that?

@norbertkross why not simply use a Row of IconButtons? wrap it with a Container with your own height set.

then save the Android JSON or iOS plist file for your project.

Во вновь созданном проекте я не могу публиковать какие-либо изменения правил Firebase. Даже простые изменения, такие как добавление новой строки в конец файла или добавление пробела.

Я чувствую, что это может быть ошибка в Firestore, но подумал, что сначала спрошу здесь …

Error saving rules –An unknown error occurred

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if false; 
    }
  }
}
