In certain scenarios, your code may fail to compile, but the compiler might not show you any errors.

In this article, we'll discuss some of the common reasons that might cause this problem. Our team is continuously improving error detection, but in the meantime, you can check for these problems in your project:

​You might be using some packages with a different version compared to the already existing packages in your project found in Pubspec.yaml file.
​

In order to resolve this problem, remove the existing pubspec dependencies.

The custom code defined in the project is different compared to the code, which might have different parameter names, null safety, return types, etc.
​

You'll need to confirm that the code matches the defined custom code. You can also compare your code structure with the boilerplate code.
​

It happens to everyone eventually: you forgot to press save. After modifying the code, if you didn't hit save, this might result in the same error.
​
To resolve this, please click the save button before compiling the code.
