Failed to evaluate expression 'handlePrimaryPointer':InternalError: No frame with index 45

Question

Code that I have written for Admin Login:

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';

class FirebaseServices {
  static Future<DocumentSnapshot> adminSignIn(id) async {
    var res =
        await FirebaseFirestore.instance.collection("admin").doc(id).get();
    return res;
  }
}

I am getting errors are given below:

+ ChromeProxyService: Failed to evaluate expression 
 'handlePrimaryPointer':InternalError: No frame with index 45.
+ ChromeProxyService: Failed to evaluate expression
 'postAcceptSlopTolerance': InternalError: No frame with index 45.
+ ChromeProxyService: Failed to evaluate expression 'FirebaseFirestore':    
  InternalError: No frame with index 32.

+ ChromeProxyService: Failed to evaluate expression 'Future': 
  InternalError: No frame with index 32.

I tried to run flutter doctor -v. And then:

If you are unable to add debug break-points and view the state of variables in the debugger, this is caused by a recent Flutter bug and you can apply the fixes down one paragraph.

If debugging works just fine, keep in mind that ChromeProxyService error messages are expected after your program was paused on a break point or unhandled exception if Async code was still executing at the time. It tells us Async code tried and of course failed to talk to the paused main thread after a debug break point or crash occurred first (Async task failed successfully). The resulting ChromeProxyService errors are a red herring. Your VSCode debugger shows a red pop-up over functions that result in an unhandled exception, that's your next clue.

If debugging break points are broken: Upgrade to Flutter v3.0.0 or downgrade to v2.10.4 using the workaround further down.

Flutter 3 upgrade:

Run flutter channel stable followed by flutter upgrade --force

For older versions of Flutter, a workaround is documented here https://github.com/flutter/flutter/issues/101224#issuecomment-1092324782:

flutter downgrade v2.10.4

(Find Flutter install dir using: flutter doctor -v)

cd <path to flutter install dir>/flutter/packages/flutter_tools

update dwds constraint in packages/flutter_tools/pubspec.yaml to 11.5.2

run flutter pub get in packages/flutter_tools directory

remove your cache: rm -rf ../../bin/cache

rebuild flutter: flutter pub get in packages/flutter_tools directory (it triggers the flutter rebuild)

This issue caused VS Code to show no local variables when debugging my Flutter project using the web-javascript renderer. I was not able to view the error message until switching the debug option to "Debug my code + packages".

Downgrading Google Chrome to version 99.0.4844.74 also works around the issue.
