You should update the package 'flutter_svg' from 0.18.1 to 0.19.3 and it should solve your issue,
it happens because of the 'nullOk' parameter that was removed in Flutter 2. You can read about it here:
https://flutter.dev/docs/release/breaking-changes/eliminating-nullok-parameters
I found this solution and it worked for me

After updating my flutter project when I was going to run the application in the android studio, I got the following error.

How can I fix this issue?

This was happened due to a pub cache conflict. The problem was fixed after executing the following command in the terminal.
dart pub cache repair
dart pub get
dart pub upgrade

I tried your solution but it does not work for me. My solution is update compileSdkVersion to 30 in my app/build.gradle.

Update the flutter toast version to latest fluttertoast version in dependencies in pubspec.yaml . It worked for me.

I got the same error. Tried updating compileSdkVersion. Didn't work for me. This solved my problem.
pubspec.yaml -->> pub upgrade
Change fluttertoast version to latest
Pub get
Run...

I really can't figure out why, does anybody know what could be the reason for this?

It seems the problem was related to the moor_ffi library, though I couldn't figure out why exactly, however switching to moor_flutter fixed it.

I already uninstall Android Studio IDE and reinstall and I try reinstalling Java JDK but don't chance anything don't know what can I do to fix this issue.

Problem:
Either flutter and dart plugins are not download properly or not configured properly with Android Studio.
Solution:
There is a way to fix this. You can just install/reinstall the Flutter & Dart plugin in android studio by steps below.
1) Open the Android Studio.
2) Open plugin preferences (File > Settings > Plugins on "Windows" & "Linux" or Preferences > Plugins on "macOS").
3) Select Browse repositories, select the Flutter plug-in and click install.
4) Click Yes when prompted to install the Dart plugin.
5) Click Restart when prompted.
6) Run command: sudo chown -R YOUR_USERNAME YOUR_FLUTTER_DIRECTORY
Example: sudo chown -R sanketvekariya /opt/flutter

Flutter plugin not installed error;. When running flutter doctor
FYI:
I have faced same issue earlier and solved by above steps. Hope you solve this soon.:)

I delete the \android\app\build folder, the issue was resolved.

In my case, the problem was that I cloned the project from repo and project was developed by my colleague months ago. So I solved the issue by updating gradle version in gradle-wrapper.properties file and also updating tools.build:gradle in android/build.gradle file.
