- Remove PostHogConfig.apiKey and the API_KEY manifest/Info.plist fallback. - Remove getFeatureFlagPayload() across Dart, web and native handlers. - Remove the debouncerDelay setter and PostHogDataMode.cellular. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
posthog-android has required minSdk 23 since 3.39.0, and the plugin's dependency range [3.71.0, 4.0.0) only resolves to versions that need it. Apps below 23 already fail the manifest merge, so this only corrects the declared value. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Removes the names deprecated in 5.x in favor of optIn/optOut and sendFeatureFlagEvent. Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…#647) Matches PostHogConfig.sendFeatureFlagEvent and the iOS/Android getFeatureFlagResult parameter. The method-channel key stays 'sendEvent'. Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* chore!: rename platform enable/disable to optIn/optOut PosthogFlutterPlatformInterface.enable()/disable() become optIn()/optOut() to match the public Posthog API renamed in #636/#638. The method-channel names sent to native stay 'enable'/'disable'. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * docs(changeset): cover direct platform callers in the opt-in/out rename Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
toMap() on the config classes and PostHogFeatureFlagResult.fromMap() are the platform-channel wire format, not a user-facing data shape. Move them to extensions and a top-level function in an unexported src/utils/channel_serialization.dart so they drop out of the public API. Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Raises the deployment targets to the posthog-ios 4.0 minimums ahead of the SDK bump, so the bump itself only changes the dependency range. Drops the availability checks that are now always true and moves the CodeQL Swift job to Xcode 26. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

💡 Motivation and Context
This is the base PR for posthog_flutter 6.0.0. It raises the iOS and macOS minimums to match posthog-ios 4.0 and removes the APIs we had already marked for removal in the next major.
It still depends on posthog-ios 3.x (
>= 3.84.0, < 4.0.0), so CI can pass before 4.0 is published. Adopting posthog-ios 4.0 (PostHog/posthog-ios#873), with its 4.x range, Xcode 26 requirement and iOS behavior changes, is in the stacked #649.Merge order: merge #649 into this branch once posthog-ios 4.0 is published, then merge this PR into
main. Merging this PR first would line up a 6.0.0 release that still uses posthog-ios 3.x, becausepublish.ymlruns on every changeset push tomain.iOS and macOS minimums

minSdkVersiongoes from 21 to 23. The plugin depends onposthog-android[3.71.0, 4.0.0), andposthog-androidhas required minSdk 23 since 3.39.0 (chore: upgrade to Kotlin 2.1.10, AGP 8.9.1, compileSdk 36, minSdk 23 posthog-android#460). An app on minSdk 21 or 22 already fails Gradle's manifest merge on that dependency, so the old 21 was stale. This doesn't change who can build, so it isn't listed as breaking. It only makes the plugin declare the floor it already has. 23 also matches Datadog's and Firebase's Flutter plugins.Merged into this branch
