I had to reinstall my windows and so I had to freshly install Android studio, flutter sdk and everything. After completing all my installations I am unable to run my project. Before upgrading the system my project was working all fine with 0 errors.

Flutter doctor:

C:\Users\Admin>flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.17.5, on Microsoft Windows [Version 10.0.18362.959], locale en-GB)

[√] Android toolchain - develop for Android devices (Android SDK version 30.0.1)
[√] Android Studio (version 4.0)

This is the first time I am moving my project from my original system to this new one.

I don't have enough reputation to comment so I will write it as an answer. Since it is the first time running the app, make sure you have an internet connection so it can download the required files.

Solution: As of now what I have done is the following:

  1. agora_rtc_engine that was showing up as error I have removed it. (I will be re-adding this package as this is required for my app)
  2. java jdk download i have added I was getting error on keytool to generate SHA1 Key Fingerprint.
  3. I updated my SHA1 Key Fingerprint in Firebase. I have to do this as I was getting error when login in using Google sign-in.

Now my App is working fine with no errors.

This might not be the correct solution for the issue, so feel free to give your suggestion on the above error that I had faced.
