I want to show data from my firebase cloudfirestore as you see in the picture:
In a Settings page I want to show all the information from the logged-in user. Here is the Settings-Code ("einstellungen" in german):
class einstellungen extends StatelessWidget {
final user = FirebaseAuth.instance.currentUser;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.red,
title: Text("Einstellungen"),
),
backgroundColor: Colors.orange,
body: SingleChildScrollView(
child: Column(
children: [
Container(
margin: const EdgeInsets.only(
left: 8.0, right: 8.0, top: 10.0, bottom: 5.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(20),
color: Colors.white.withOpacity(0.2),
),
child: Column(
children: [
Align(
alignment: Alignment.centerLeft,
child: Padding(
padding: const EdgeInsets.all(10.0),
child: Text('Benutzer:',
style: TextStyle(fontWeight: FontWeight.bold)),
),
),
Align(
alignment: Alignment.centerLeft,
child: Padding(
padding: const EdgeInsets.only(
bottom: 10.0, left: 10.0, right: 10.0),
child: Text(''),

),
Align(

child: Padding(
padding: const EdgeInsets.all(10.0),

child: Padding(
padding: const EdgeInsets.only(

),
Align(

child: Padding(
padding: const EdgeInsets.all(10.0),
child: Text('E-Mail:',

child: Padding(
padding: const EdgeInsets.only(
bottom: 10.0, left: 10.0, right: 10.0),
child: Text(''), // here should print the email address from firestore
),
),
Text(''),
Align(

child: Padding(
padding: const EdgeInsets.all(10.0),

),
Padding(

child: Divider(),

SizedBox(height: 10),
if (user.uid != null)
Text(
'Cloud User-ID: ' + user.uid,
style: TextStyle(color: Colors.black),
),
SizedBox(height: 10),
Padding(
padding: const EdgeInsets.all(10.0),

),
);
}
}
As you can see I do get information from the FirebaseAuth.instance.currentUser
, so the userid
from the logged-in user is shown. But I want the information from the userdata in firestore too.
Can anybody help with this basic firestore-trick I guess? I'm new in flutter. Tried a lot but cannot find solutions which fit for my example. Thanks a lot
You should to create query to Firestore and get user details.
If you know the user ID, you can call doc
function to create query.
@override
Widget build(BuildContext context) {
CollectionReference users = FirebaseFirestore.instance.collection('users');
return FutureBuilder<DocumentSnapshot>(
future: users.doc(documentId).get(),
builder:
(BuildContext context, AsyncSnapshot<DocumentSnapshot> snapshot) {
if (snapshot.hasError) {
return Text("Something went wrong");
}
if (snapshot.connectionState == ConnectionState.done) {
Map<String, dynamic> data = snapshot.data.data();
return Text("Full Name: ${data['full_name']} ${data['last_name']}");
}
return Text("loading");
},
);
}
Or use where expression to find user by its attributes (for example email):
FirebaseFirestore.instance
.collection('users')
.where('email', isEqualTo: "test@yahoo.de")
.get()
