So I have this code here and I would like to display post details from firebase for the post which I have clicked on, but instead, it lists post details for every single post in the database one after another.
Can anyone help me figure out how I can make it so that when A post is clicked, details will show for only the post which was clicked, and not for all of the posts? Any help would be greatly appreciated, thank you.
The Info I would like to display on the post is
postTitle
postDesc
postAuthor
Here is what the firebase looks like

I also reference crud.dart in that code, so incase you need it, here it is:
import 'package:cloud_firestore/cloud_firestore.dart';
import 'dart:collection';
class CrudMethods {
Future<void> addData(blogData) async {
print(blogData);
FirebaseFirestore.instance
.collection("blogs")
.add(blogData)
.then((value) => print(value))
.catchError((e) {
print(e);
});
}
getData() async {
return await FirebaseFirestore.instance
.collection("blogs")
.orderBy("ts", descending: true)
.get();
}
}
Thank you again for any help!
First I would recommend to modelize your data in an object for exemple a class Article that is easier to serialize and manipulate.
Then instead of requesting another time the database you should save your data in a List<Article> for example then you only update this list on refresh from your main page. That way you don'y manipulate a QuerySnapshot or Future but just your list of objects.
Finally and to answer your question, you could simply pass the clicked item Article to your details page and only display its content. Because here, you have the same construction as your main page with the same request that is resent.
Usually you can build your route like that (adding a parameter to your details with the index you clicked on for example)
onPressed: () {
Navigator.push(context,
MaterialPageRoute(builder: (context) => DetailPage(article: _data[i])));
},
Here is an article on serialization from Flutter docs, it shows how to build your model with the toMap, toJson and fromJson methods.
At 54 I'm self-learning Flutter and have come a long way. I am stuck (again) with a speed-bump concerning my implementation of Firebase. Although I am getting the very basic of displaying a line of data for each record the problem is getting to the details of each record. I believe the issue is that I am not referencing the record ID.
When looking at endless examples I also believe my code to display a ListView of records is bloated making it more difficult to grab a record and display all fields (edit screen).
I want to click the "Walsh-Test" links to view all fields and update. I can create a new edit/update screen my initial problem is opening the screen to the selected record.
Any advice would be greatly appreciated.

I understand that you want to go to another page (Edit Screen) onTapping the alarm tile.
So, my suggestion is to use A ListTile widget instead of the row widget you are using.
You can read about ListTile's onTap property, here
Regarding your routing to a new screen/page, you'll have to make use of MaterialPageRoute to create a new route and using Navigator's push method you can push it onto your Material App.
Attaching an example code that uses Navigator to go to different pages, you need the BuildContext of your app. Here is an example of how you can get it:
import 'package:flutter/material.dart';
import 'package:rate_your_professor/screens/firstScreen.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Some App',
home: SomeApp(),
);
}
}
class SomeApp extends StatelessWidget {
Widget getListView(BuildContext context) {
var listView = ListView(
children: <Widget>[
Text(
"XXXXXXXXXXXXXXX",
textDirection: TextDirection.rtl,
textAlign: TextAlign.center,
),
ListTile(
leading: Icon(Icons.location_city),
title: Text("XXXXX ", textDirection: TextDirection.rtl),
subtitle: Text(
"XXXXXXXXXX",
textDirection: TextDirection.rtl,
),
onTap: () {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => YourNewPage(),
),
);
},
),
],
);
return listView;
}
#override
Widget build(BuildContext context) {
return Scaffold(body: getListView(context));
}
}
I am trying to figure out how to do this.
If I pass the document ID hardcoded it works. But Since I have multiple pages, I am trying to figure out how to pass it and then query it..
My main page has the following.
import 'package:flutter/material.dart';

class _HomeState extends State<Home> {
StreamSubscription<QuerySnapshot> subscription;
List<DocumentSnapshot> snapshot;
Query collectionReference = Firestore.instance.collection("mainCategories").orderBy("title");
void initState() {
subscription = collectionReference.snapshots().listen((datasnapshot) {
setState(() {
snapshot = datasnapshot.documents;
});
});
super.initState();
}
#override
void dispose() {
subscription.cancel(); //Streams must be closed when not needed
super.dispose();
}
passData(DocumentSnapshot snap, String cat, String title) {
print(cat);
Navigator.of(context).push(
MaterialPageRoute(builder: (context) => Category(snapshot: snap, category: cat, title: title,)));
}

I have realised that the code looks shady on the comment so let me make an answer.
What you are trying to do is currently not supported in flutter as can be seen at these GitHub issues 1 and 2.
Change your code to,
class _CategoryState extends State<Category>{
StreamSubscription<QuerySnapshot> subscription;
List<DocumentSnapshot> snapshot;
Query collectionReference;
void initState() {
collectionReference = Firestore.instance.collection("mainCategories").document(widget.category).collection("subCategories").orderBy("title");
subscription = collectionReference.snapshots().listen((datasnapshot) {
setState(() {
snapshot = datasnapshot.documents;
});
});
super.initState();
}
...
Hope this helps.

I am working on the Flutter code that follows. I have issues with the second button called "Regitrese". Every place I have looked work with statelesswidgets so I'm not sure how to fix it. I tried changing the void to put on it home: MyHomePage() and put MyHomePage to statefull instead of taking the statefull from MyApp bus it shows a mistake Missing concrete implementation of StatefulWidget.createState. I am not sure how is it supposed to go. Can you make a button work in a StatefulWidget? Is there a trick I am not seeing?
void main()=> runApp(new MyApp());
class MyApp extends StatefulWidget{
#override
State<StatefulWidget> createState(){
return new MyHomePage();
}
}
class MyHomePage extends State<MyApp>{
final TextEditingController rutController = TextEditingController();
final TextEditingController passwordController = TextEditingController();
var _rut, _password;
#override
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
body: new Container(
padding: const EdgeInsets.all(50.0),
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
TextFormField(
controller: this.rutController,

labelText: 'Rut',
hintText: 'eg. 154683265',
suffixIcon: IconButton(
icon: Icon(Icons.clear),
onPressed: () {
rutController.clear();
}
)
),
),
TextFormField(
controller: this.passwordController,

RaisedButton(

MaterialPageRoute(builder(context)=>SelectUserPage())
)
},
child: Text('Registrese'),
),

),

}
}

#override
Widget build(BuildContext context){
return new Container(

The thing is that you need to access a context below the MaterialApp widget that adds the Navigator to the tree. If you look at your code the context is above it.
One way to solve it is to move a part of the tree to another widget.
Or you can use a Builder around your button or around the Column as in the following code:
Builder(
builder: (context) => RaisedButton(
onPressed: () {
Navigator.push(context,
MaterialPageRoute(
builder: (context) => SelectUserType()));
},
child: Text('Registrese'),
),
),

Column in flutter doesn't have scrolling ability. The issue is your data from firebase cannot be fit inside a single screen. That's why overflow error was thrown. Use ListView instead of Column which has the scrolling ability.
Column widget for available room in the device to get qll data in firebase and also to get scroll effect you can use FirebaseAnimatedList.
For an Olx like gridview with text over image, here is a sample. Try it out and change your question because it might be misleading.
