pubspec.yaml find not found

[saksham-gt]

I'm unable to find pubspec.yaml file of this project. And, also (idk why I did this) I tried to copy pubspec.yaml file from other my other projects but it showed
"Target file "lib/main.dart" not found."

Please help how do I overcome this pubspec.yaml problem?

pubspec.yaml file will automatically create when you initiate your flutter project. If just wanna copy-paste the code then, go-to the "lib" folder and paste all the code file.

Don't forget to use flutter pub get
