Search screen not displaying anything when I search

[sharmahal]

initially my code was working fine but after working more on the project , I got this error
[NoSuchMethodError: The method 'where' was called on null.
Receiver: null
Tried calling: where(Closure: (User) => bool)
See also:
https://flutter.dev/docs/testing/errors]

then I changed my a funtion and wrote this -
` buildSuggestions(String query) {
final List suggestionList = query.isEmpty
? []
: userList != null
? userList.where((User user) {
String _getUsername = user.username.toLowerCase();
String _query = query.toLowerCase();
String _getName = user.name.toLowerCase();
bool matchesUsername = _getUsername.contains(_query);
bool matchesName = _getName.contains(_query);

  return (matchesUsername || matchesName);

  // (User user) => (user.username.toLowerCase().contains(query.toLowerCase()) ||
  //     (user.name.toLowerCase().contains(query.toLowerCase()))),
}).toList()
    : [];`

but still the search screen doesnt display the user it used to display intially

Try copying the code from the repository as it is , it will work.

W/Firestore( 9173): (21.3.0) [FirestoreCallCredentials]: Failed to get token: com.google.firebase.firestore.FirebaseFirestoreException: getToken aborted due to token change.

Before searching, as soon as you click the search button in the home page, I am getting this error in the terminal.

I fixed it by modifying the database rules.

rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { match /{document=**} { allow read; allow write; } } }

This should set it right.
