转到androidx后，应怎么改，下面的代码 HasSupportFragmentInjector 报红出错

import dagger.android.DispatchingAndroidInjector
import dagger.android.support.HasSupportFragmentInjector
import javax.inject.Inject

/**
 * A login screen that offers login via email/password.
 */
class ActMain constructor() : BaseAct<ActMainBinding?>(R.layout.act_main, R.id.frm_Main),
    HasSupportFragmentInjector, SetChangeListener, UserChangeListener {
    @Inject
    var dispatchingAndroidInjector: DispatchingAndroidInjector<Fragment?>? = null
    private var isEnWin: Boolean = false
    private var isFirstSet: Boolean = true
    protected var receiver: BroadcastReceiver? = object : BroadcastReceiver() {
        public override fun onReceive(context: Context?, intent: Intent?) {
            if (isEnWin) finish()
        }
    }

dagger.android.support.HasSupportFragmentInjector如何转到androidx
