[Version: 2.0.0][Build] Unresolved reference: PerformanceTracker in Kotlin

[bgenidy]

Describe what happened
Was attempting to migrate over to datadog_flutter_plugin 2.0.0

Steps to reproduce the issue:

1. Upgrade to datadog_flutter_plugin 2.0.0
2. Have the following configuration

final loggerConfiguration = DatadogConfiguration(
  clientToken: '', // set as empty in dev
  env: 'dev',
  site: DatadogSite.us1,
  nativeCrashReportEnabled: true,
  loggingConfiguration: DatadogLoggingConfiguration(),
  rumConfiguration: null,
)..enableHttpTracking();

await DatadogSdk.instance
      .initialize(loggerConfiguration, TrackingConsent.granted);

3. build a bundle for android, get the below exception

This was fixed by me running /gradlew assembleDebug --stacktrace which created a clean build. I had datadog version 1.2.1 before. So normal upgrade might not have cleaned up all the necessary metadata files causing this issue.
