Flutter error: cannot find symbol import com.google.firebase.firestore.LoadBundleTaskProgress;

I have a firebase user app that let the users sign up and show their data and edit it. This error happens when I try to run the app on the emulator. I wrote most of this app on sdk 2.11.0 then changed to 2.12.0 to suit null safety yet, I don't know if this is the reason.

The error:

I think it is related to the SDK update, the issue might be caused because some of your components don’t suit null safety and is solved by updating them to a version where they accept it. Here you can find related information about that issue and its possible solutions. These are the possible solutions:

Solution 1

As I updated my SDK version to null safety all we need to do is just update your firebase_messaging in pusbpec.yaml to version a that supports null-safety (for example: firebase_messaging: ^10.0.0), and call flutter pub get from terminal

  • Open pubspec.yaml file.
  • Get the latest version of firebase_messaging from here.
  • Updated to latest version.
  • Then flutter pub get.

That’s all.

Solution 2

First, get the latest versions of your firebase dependencies from pub.dev

Run the commands:

flutter pub upgrade
flutter pub get
flutter clean

Invalidate caches, restart and then try running the app.

In the solution 1 the firebase_messaging dependency is updated, I was looking for the exact dependency, which seems to be LoadBundleTaskProgress, but all I could find is that it was in the cloud_firestore plugin, and to install it you would need to do as follows:

Run this command:

With Flutter:

$ flutter pub add cloud_firestore

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:   
    cloud_firestore: ^2.5.3

If you already tried this and the message is still showing you might need to check your imports as well.
