Hi I'm getting the following error when I run flutter run:

Launching lib/main.dart on Chrome in debug mode...
../../../flutter/.pub-cache/hosted/pub.dartlang.org/cloud_firestore_web-2.6.9/lib/src/internals.dart:11:20: Error: Method not found:
'guardWebExceptions'.
  return internals.guardWebExceptions(
                   ^^^^^^^^^^^^^^^^^^
Waiting for connection from debug service on Chrome...             58.4s
Failed to compile application.

I ran flutter upgrade to update everything:

Flutter 2.10.2 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 097d3313d8 (7 days ago) • 2022-02-18 19:33:08 -0600
Engine • revision a83ed0e5e3
Tools • Dart 2.16.1 • DevTools 2.9.2

and I resolved the issue by adding the following to pubspec.yaml:

dependency_overrides:
  cloud_firestore_web: 2.6.5

I am having the same error message but after upgrading and adding the dependency override it is still not fixed.

Any update on this issue? I have the same problem.

I have the same or similar issue with Cloud Firestore.

I have recently upgraded Flutter (Channel stable, 2.10.2) and Dart (SDK version: 2.16.1 (stable)). I also added a dependency override to my pubspec.yaml for "cloud_firestore_platform_interface: 5.4.13". I am getting the following error:

"../../../.pub-cache/hosted/pub.dartlang.org/cloud_firestore_web-2.6.9/lib/src/internals.dart:11:20: Error: Method not found: 'guardWebExceptions'.
return internals.guardWebExceptions(
