+- chore: update languageVersion and apiVersion from 1.8 to 2.0 on Android to be compatible with Kotlin 2.3 ([#245](https://github.com/PostHog/posthog-flutter/pull/245))
+
 # 5.10.0
 
 - feat: Add `onFeatureFlags` callback to `PostHogConfig` to get notified when feature flags are loaded. Use `Posthog().getFeatureFlag()` or `Posthog().isFeatureEnabled()` within the callback to access fresh flag values. ([#224](https://github.com/PostHog/posthog-flutter/pull/224))
