Having trouble? Try firebase deploy --help

build fails because getting error in FirebaseMessagingPlugin.m. the error is generated from line 176. here's the code on line 176:

[_channel invokeMethod:@"onToken" arguments:[[FIRInstanceID instanceID] token]];

using legacy system. any solutions? thanks.

I get this error message. I checked the getfeed url correctly. Where's the trouble?

I was finally able to get everything to build correctly and was able to get fluttergram to launch in my simulator and on my physical device. Both locations prompted me to sign in with google, which I used an existing account and the authentication seemed to work correctly. I do see the new userid show up in my Firebase instance. But after that initial auth fluttergram appears to be frozen. I see the main splash page with the same "Sign in with Google" option, but I am unable to tap on that sign in anymore. Force close the app and launch it again and it goes directly to the frozen screen. Same exact results on using the simulator and my iphone. I'm honestly not sure where to start with this issue, any suggestions? Thank you!

After updating flutter and some packages the Google SignIn is not working anymore. It seems that the package changed its procedure with the newest version.

https://pub.dartlang.org/packages/firebase_auth/versions/0.8.4+2 https://github.com/flutter/flutter/issues/27133

Should not be too difficult too update the code.

Thank you and btw great project and good job!

Hi, this is awesome project. I've cloned it, follow steps, creates indexes. All pages are now working except the home page, which display data returned by getFeed.js. I've tried to see, in my browser with url, if something is returns : YES I have a result by empty one. But I have 3 posts from 2 different users.

Any ideas ?

Thanks

Reproducing

• Clean database users and authentications
• Delete app from emulator
• Run application
• Login with google account
• Write username
• Press next or confirmation on keyboard
• Username field will erase
• Write again
• Press next or confirmation on keyboard
• Username will be accepted and you will be redirected

Debug console: https://pastebin.com/XSe6RReT

Edit: Links are broken and I don't recommend anymore this approach.

• How it is working: Main starts, then set timestamps true in firestore while is loading FluttergramApp. The pageController and _firebaseMessaging are global variables. The _userLocation and the googleSignIn status are get on initState of the HomePage and passed to the creation of the CurrentUser calling CurrentUser.signInWithGoogle(silently: true, userLocation: _userLocation). If is signed it calls it silently: true, if not, silently: false. Then the signInWithGoogle methods creates the CurrentUser.instance. After that the HomePage is rebuild with home screen (feed screen) and notifications are set:

@override
  Widget build(BuildContext context) {

    print('[HomePage] [Build] START');

    if (CurrentUser.instance != null) {

      if (!_notificationsAreSet) _setUpNotifications();

      print('[HomePage] [Build] CurrentUser.instance != null');
      print('[HomePage] [Build] building home screen');
      return Scaffold( ........
    }
    print('[RootPage] [Build] CurrentUser.instance == null');
    print('[RootPage] [Build] building login screen, _loadingIcon: $_loadingIcon');
    return _buildLoginScreen();
  }

factory CurrentUser._singletonConstructor({DocumentSnapshot documentSnapshot, String username, Address userLocation}) {

    // Creates from snapshot from document from database (any login that isnt the first)
    if (documentSnapshot != null) {
      print('[CurrentUser] [Constructor] creating from document snapshot');

      if (documentSnapshot.data != null) {
        print('[CurrentUser] [Constructor] documentSnapshot.data != null');
        return CurrentUser(
          bio: documentSnapshot.data['bio'] == null ? '' : documentSnapshot.data['bio'],
          displayName: documentSnapshot.data['displayName'],
          username: documentSnapshot.data['username'],
          id:  documentSnapshot.data['uid'],
          photoUrl: documentSnapshot.data['photoURL'],
          followers: documentSnapshot.data['followers'] == null ? new Map<dynamic, dynamic>() : documentSnapshot.data['followers'],
          following: documentSnapshot.data['following'] == null ? new Map<dynamic, dynamic>() : documentSnapshot.data['following'],
          address: userLocation
        );
      }
      else {
        print('[CurrentUser] [Constructor] documentSnapshot.data == null');
      }
    }

    // Creates from Google account
    if (googleSignIn.currentUser != null) {

• Created CurrentUser class in user.dart file that is a singleton with non-final variables that holds the user address and has methods to sign in, create the current user from google (first login) or from document (any other login), sign out and update informations.
• Moved FirebaseAuth and GoogleSignIn and everything related to authentication and sign in to CurrentUser class.
• Removed the "take a picture blank screen" (if you click on "+" button on bottom bar, it opens a dialog that with 3 option -> take a picture / choose from gallery / cancel).
• Removed "create username screen" (username is generated with display name and random numbers on first login).
• Removed unnecessary widgets when showing camera file thumbnail.
• Turned many public methods and variables in private.
• Added dialog when clicking on "3 dots icon" on top right of the image showing "edit post" / "delete post" / "cancel"
• Imported circular_profile_avatar package to add border and elevation on CircleAvatar

Main.dart overall:

User.dart overall:

Upload_page.dart overall:

Profile_page.dart overall:

Feed.dart overall:

Console startup:

Things to do:

• Save image resolution after picking it so you know the orientation (portrait / landscape) to make the image post on feed list with the right size (the way it is working now, portrait pphotos are bigger then original instagram).

Edit: sorry for broken links

the argument type Context cant be assign to parameter type BuildContext error in alert dialog box

return showDialog( context: context, //here error barrierDismissible: false, // user must tap button!

I am having trouble trying to get the dependencies to work... looks like http is the start of the mess, but then it moves on to things like:

Running "flutter packages get" in fluttergram...
Because cached_network_image >=0.4.1 <0.4.2 depends on flutter_cache_manager ^0.1.1 and cached_network_image >=0.4.0 <0.4.1 depends on flutter_cache_manager ^0.1.0, cached_network_image >=0.4.0 <0.4.2 requires flutter_cache_manager ^0.1.0. And because cached_network_image >=0.4.2 depends on flutter_cache_manager ^0.1.2 which depends on http ^0.11.3+14, cached_network_image >=0.4.0 requires http ^0.11.3+14. So, because Fluttergram depends on both cached_network_image ^0.4.0 and http ^0.12.0, version solving failed.

Firestore.instance.document("insta_users/$profileId").updateData({
      'followers.$currentUserId': true
      //firestore plugin doesnt support deleting, so it must be nulled / falsed
    });

    Firestore.instance.document("insta_users/$currentUserId").updateData({
      'following.$profileId': true
      //firestore plugin doesnt support deleting, so it must be nulled / falsed
});

If each user (document) of the "insta_users" collection had inners collections called "followers" and "followings" that contains a string with the id of the user you are following/being followed, you could delete them instead of setting null.

I know this project wasn't designed for millions of users and probably you won't change it (because it needs to recode many things) but I think it's good to point this out.

Edit: Or even better, you don't need a new inner collection, you could just keep a followersIds field that holds a List of String and a followingsIds field that holds a List of String too and everytime the list change you recreate it and send the entire list again.

Anyway, I don't know if I'm right. Just thinking that this thing of setting null because you cant delete is a little weird.

Searched for a user called "Pendulum Pala" with username "pendulumpala". Typing: Pendulum -> found pendulum -> not found pendulumpala -> not found pendulum pala -> not found pendulum Pala -> not found Pendulum Pala -> found Pala -> found pala -> not found

I'm gonna try to improve that search and then I come back here.
