I have the following courses array in Firestore:
How can I print all the items in Courses array?
I have the following code which currently just fetches the data from Firestore:
printAllValuesFromArray() {
var courses = FirebaseFirestore.instance
.collection('CurrentCourses')
.doc(user.uid)
.get()
.then((value) {
return value['courses'];
});
}
You are correctly fetching the document of the user, all you need is to just print the value like the following:
Future<void> printAllValuesFromArray() {
return FirebaseFirestore.instance
.collection('CurrentCourses')
.doc(user.uid)
.get()
.then((document) {
final courses = document['Courses'];
for (var course in courses) {
print(course);
}
});
}
Note: You were using incorrect key to access the courses from the document which was courses while the correct one is Courses with capital C,
value['courses'].forEach((val) {
print(val);
});
// Can you try this
You can try this,
printallvaluesfromarray() {
var courses = FirebaseFirestore.instance
.collection('CurrentCourses')
.doc(user.uid)
.get()
.then((value) {
print(value.toString())
return value['courses'];
});
}
