Flutter App Crashes on IOS with Memory Leak Error While Connecting to Firestore

[SherifSaidElahl]

I have a flutter app that is working perfectly on Android, now trying to test it on IOS.

Device: Real Iphone 7 - IOS: 15.7.3

problem:

App crashes and shutsdown once it try to connect to the first firestore stream builder in the app and it generates a memory leak error like the below. what is causing the problem?

Error:

thread #10, name = 'io.flutter.1.ui', stop reason = EXC_RESOURCE RESOURCE_TYPE_MEMORY (limit=1450 MB, unused=0x0)

code:

class _AppConfigPageState extends State<AppConfigPage> { 
@override
 Widget build(BuildContext context) {
    debugPrint("AppConfig"); --> this is printed successfully
    // it crashes here exactly.
    return StreamBuilder<QuerySnapshot>(
     stream: FirebaseFirestore.instance
        .collection('AppConfigsCollection')
        .snapshots(),
     builder: (context, snapshot) {
      if (!snapshot.hasData) {
        //it never reaches here.
        return Container();
      } else {
        if (snapshot.data!.docs.isEmpty) {
          //it never reaches here.
          return CheckYourConnectionPage();
        } else {
        //it nevers reaches here.
        rest of code.
        }}});}}
