I'm unable to set the viewBinding in Android Studio

Question

I'm stucked like 5 days in this problem! I'm unable to bind the view using viewBinding clause in Android Studio, I believe the problem is in "build.gradle" file.

Initially, I tried to build the project in the way that I knew:

buildFeatures { viewBinding true }

But it didn't work... I went to the Android Official page to see, and apparently they changed the syntax to:

viewBinding { enabled = true }

Even so, it shows an error: the word "enabled" is subbed and do not let the gradle build the program.

I have also tried:

viewBinding { enable = true }
viewBinding { enable }
viewBinding { enable true }
 
buildFeatures { viewBinding { enabled = true } }
buildFeatures { viewBinding.isEnabled } 
 
// Among numerous other possibilities...

I also tried to define the viewBinding globally, in gradle.properties:

android.viewBinding.enabled=true

Did not work.

I looked at the imports as well:

import com.example.mvvmstudy.databinding.ActivityMainBinding
// The mistake does not seems to be here

As well, I tried to verify the gradle version, but it seems to be up to date, I'm using version 8.3 with the 8.1.1 plugin.

What may be the problem?? I have already rebuild the project many many times, I did 2 other new projects and the issue still there hahahahaha

The project is just an exemplo about how MVVM works, I defined a button just to set a Toast and see the binding works, but I'm not been able to do it...

I did already seen: 1 - When I add viewBinding in gradle in Android Studio, it comes an error

2 - What's the difference between viewBinding enabled true and buildfeatures viewBinding true

3 - cannot access viewBinding

And some others, but neither worked...

In Gradle Kotlin DSL (KTS), the syntax is different from Groovy. Here is the correct way to enable View Binding in an Android project using Gradle Kotlin DSL:

buildFeatures {
        viewBinding = true
}

Instead of

buildFeatures {
        viewBinding true
}

In Gradle Kotlin DSL, assignments are done using the = operator.
