Hello I have a problem with my code. I want to display a list of a users from firebase, but im stuck at the end. the line of code shuld look like this:
userName: searchSnapshopt.documents[index].data["name"]);
but after the update, there are no documents anymore and there is "docs" and it breaks everything down for me
here is my code
class _SearchScrState extends State<SearchScr> {
DatabaseMethods databaseMethods = new DatabaseMethods();
TextEditingController searchTextEditingController =
new TextEditingController();
QuerySnapshot searchSnapshopt;
initiateSearch() {
databaseMethods
.getUserByUsername(searchTextEditingController.text)
.then((val) {
setState(() {
searchSnapshopt = val;
});
});
}
Widget searchList() {
return searchSnapshopt != null
? ListView.builder(
itemCount: searchSnapshopt.docChanges.length,
shrinkWrap: true,
itemBuilder: (context, index) {
return SearchTile(
userName: searchSnapshopt.docs[0].data("name"));
})
: Container();
}Ok i have a solution, just change this
userName: searchSnapshopt.docs[index].data("name")
to this:
userName: searchSnapshopt.docs[index].get("name")
and now works
Try this:
class _SearchScrState extends State<SearchScr> {
DatabaseMethods databaseMethods = new DatabaseMethods();
TextEditingController searchTextEditingController =
new TextEditingController();
QuerySnapshot searchSnapshopt;
initiateSearch() {
databaseMethods
.getUserByUsername(searchTextEditingController.text)
.then((val) {
setState(() {
searchSnapshopt = val;
});
});
}
Widget searchList() {
return searchSnapshopt != null
? ListView.builder(
itemCount: searchSnapshopt.docChanges.length,
shrinkWrap: true,
itemBuilder: (context, index) {
return SearchTile(
userName: searchSnapshopt.docs[index].get("name"));
})
: Container();
}
