Kotlin + Dagger2 appears Dagger does not support injection into private fields solution

Using KT + Dagger2 in the project, when injecting, the code is as follows:

class MainActivity : AppCompatActivity() {
    
    

    @Inject
    var presenter : Presenter? = null
	

When the code is compiled, an error is reported directly:

In fact, it has been said very clearly that Dagger does not support the injection of private attributes, so this is more embarrassing, because the decompiled code Ktin is as follows:presenter

public final class MainActivity extends androidx.appcompat.app.AppCompatActivity {
    
    
    @org.jetbrains.annotations.Nullable()
    @javax.inject.Inject()
    private com.xing.jetpacklearn.Presenter presenter;
    
    public MainActivity() {
    
    
        super();
    }
    

The attribute at this time presenteris private, which does not meet the requirements of Dagger. How should we deal with it? Two methods:

Method 1:
The code is as follows:

---

class MainActivity : AppCompatActivity() {
    
    

     var presenter : Presenter? = null
        @Inject set
	
}

Just add it to the set method of the attribute @Inject.

---

Method 2: Use `@JvmField` keyword modification:

class MainActivity : AppCompatActivity() {
    
    

    @Inject
    @JvmField
   var presenter : Presenter? = null
   
}

can be resolved.
