LeakCanary Setup

Ensure that you already have an explicit dependency in your application's build.gradle including the plugin dependency, e.g.

dependencies {
  debugImplementation 'com.facebook.flipper:flipper-leakcanary2-plugin:0.76.0'
  debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.6'
}

Update your the onCreate method in you Application to add the LeakCanary2 plugin to Flipper and the Flipper listener to LeakCanary

import com.facebook.flipper.plugins.leakcanary2.FlipperLeakListener
import com.facebook.flipper.plugins.leakcanary2.LeakCanary2FlipperPlugin

...

  override fun onCreate() {
    super.onCreate()
    setupFlipper()

    /*
    set the flipper listener in leak canary config
    */
    LeakCanary.config = LeakCanary.config.copy(
        onHeapAnalyzedListener = FlipperLeakListener()
    )

    SoLoader.init(this, false)

    if (BuildConfig.DEBUG && FlipperUtils.shouldEnableFlipper(this)) {
      val client = AndroidFlipperClient.getInstance(this)
      /*
      add leak canary plugin to flipper
      */
      client.addPlugin(LeakCanary2FlipperPlugin())
      client.start()
    }
  }

That's it!
